The pictographs schematically visualize the CT morphologic appearance of the respective SDC. Leakage of these fragile new blood vessels is held responsible for additional influx of blood, proteins, and fluid and, thereby, for the increase in size of the cSDH.39,52⇓⇓⇓–56 Formation of septa is considered a consequence of repeated rebleeding events and may lead to chamber-like structures with multiple fluid-fluid levels appearing differently with regard to density or signal intensity (Fig 1I).57 A pathologically expanding SDHy or SDHHy is considered the precursor of the cSDH (blue box in Fig 2).20,22,27,34,49 The direct conversion of an acute SDH into a cSDH is infrequently observed in adult cases only and could not be simulated in animal experiments.20,58,59, Given the inherent heterogeneity of traumatization and the resulting diversity of SDC appearance and SDC combinations, precise dating of SDCs based on neuroimaging alone is unrealistic. 4.

METHODS: Patients with arachnoid cysts and intracystic hemorrhage, adjacent subdural hygroma, or adjacent subdural hematoma treated at a single institution from 2005 to 2010 were retrospectively identified. Subdural hygroma is an uncommon complication after lumbar puncture. However, such statements may be helpful if a “minimum age concept” is applied. Unable to process the form. In many cases of an SDC diagnosed as SDHy, it may be assumed that the SDC is actually the homogeneous variant of the SDHHy (Fig 1D) because the blood component may sometimes be relatively small and/or very “young” (hyperacute); furthermore, an intense mixture of blood and CSF may be present.27⇓–29 Hence, in our experience, SDHy and SDHHy are used interchangeably or synonymously in radiology reports. Neurosurgery. Subdural hematoma (SDH) forms when there is hemorrhage into the potential space between the dura and the arachnoid membranes. In light of serious physical, psychological, and legal consequences, physical child abuse attracts increasing attention in terms of health policy and health economy.1⇓–3 Head injuries represent the most frequent cause of lethal outcome and mainly relate to children within their first and second years of life.4⇓–6 Currently, the term “abusive head trauma” (AHT) is used for any nonaccidental or inflicted head injuries in pediatrics.7⇓–9, AHT has a worldwide incidence of 14–30/100,000 live births among children younger than 1 year of age.5,10⇓⇓–13 Additionally, a high amount of underreporting has to be assumed because many cases are not identified due to subclinical courses, nonspecific symptoms, or missing medical consultation.14 Meta-analyses on the outcome revealed an average mortality rate of around 20% among children younger than 2 years of age.15 Survivors showed severe disability (eg, tetraplegia, epilepsy, or blindness) in ∼34%, and moderate disability (eg, hemiplegia, memory and attention difficulties) in ∼25% of the cases.15.

Supernatant (and thus an integral part of blood) changed by gravity (serum separation/blood sedimentation/hematocrit effect), in the sense of an SDH. In contrast to the situation in adults, genuine cSDHs are relatively rare in infants.22,36⇓–38. 1. Two intact BVs can be found next to the superior sagittal sinus (arrow shows 1 BV). Diagnosing AHT always requires the joint assessment of numerous investigation results from pediatrics, ophthalmology, neurosurgery, laboratory medicine, forensic medicine, and radiology.7,16 Pediatric neuroimaging by CT and MR imaging plays a key role in this strategy.7,16,17 Traumatic brain injuries and extra-axial indicators of AHT can be depicted and evaluated across time.

B, SDHy (nonenhanced CT): a 2-month-old boy with wide, homogeneously hypodense (or CSF-isodense) SDCs over both frontoparietal regions; no neomembranes or septa. The latter does not communicate freely with the SAS and is encapsulated by a neomembrane bearing capillaries. Normally, SDEs and SDEms are nontraumatic, but in rare cases, SDEms may originate following penetrating head trauma or craniotomy, which, of course, is usually known in the clinical setting. Of those cases, 5 pediatric patients with a delayed postoperative complication involving hydrocephalus and subdural hygromas were identified. Deltour P, Lemmerling M, Bauters W et-al. ... raised ICP or subdural hygroma. J Trauma. The neuroradiologic analysis and assessment of subdural collections may decisively contribute to answering differential diagnostic and forensic questions. Other imaging findings might have the potential to support the age estimation of AHT cases in the future—that is, parenchymal shear injuries, bridging vein thromboses/venous injuries, brain edema, subdural neomembranes (see also below: “Hypodense Subdurals: Acute or Chronic?”), the size of the SDC, or other signs of brain damage.22,63,71 However, as long as large systematic studies on these topics are missing, being cautious with time-related statements on SDCs is recommended. Simplified schematic drawing of the development of cSDHs via SDHys/SDHHys according to Hymel et al,20 Hedlund,22 Wittschieber et al,27 Zouros et al,29Lee et al,34 and Lee.49 The findings within the yellow box demonstrate the possible SDC entities following AHT that can often be found during initial cross-sectional neuroimaging.

Several distinguishing criteria have been proposed (Table 3) to address this question.22,27⇓–29,33,66,74 The most important criterion is the presence of subdural neomembranes, septa, or chamber-like formations characterizing cSDHs. A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Concern for AHT in a 4-month-old boy. A common variant of the abusive head trauma is the shaken baby syndrome. Kabir SM, Jennings SJ, Makris D. Posterior fossa subdural hygroma with supratentorial chronic subdural haematoma. The pathophysiologic background is explained. However, the large body of literature allows the differentiation of at least the following 6 entities. Mixed-density and hypodense SDCs—2 typical problem constellations during the initial CT investigationa, Currently, from the pathophysiologic point of view, chronic subdural hematoma (cSDH) is considered a separate SDC entity.23 cSDH denotes a serosanguinous, petroleum-, or crankcase-like fluid collection surrounded and sometimes loculated (divided into compartments) by neomembranes (Fig 1G, -I).26,33⇓–35 Neomembranes contain numerous new blood vessels leading to accumulation of contrast agent in neuroimaging studies.22,27 The presence of neomembranes represents an important criterion for distinguishing cSDH and SDHy. © 2021 by the American Society of Neuroradiology | Print ISSN: 0195-6108 Online ISSN: 1936-959X. Other potential pathogenic mechanisms for posttraumatic low attenuation subdural fluid include a hygroma due to a tear in the arachnoid membrane, 6 an effusion from traumatized meninges, 7,8 and a hyperacute hematoma with fresh unclotted blood or areas of unretracted semiliquid clot. Key Words subdural hematoma, subdural hygroma, intracranial hemorrhage Introduction The accurate age determination of a subdural hemorrhage is one of the most common and basic assessments in the setting of head trauma. CSDH is defined as a fluid collection within the layers of the dura mater. 11 Persistent tears in the lining might lead to cyst resolution in rare cases. SDC entities in AHT cases. Two unruptured/nonhemorrhagic controls were matched to each case based on patient age, sex, anatomical cyst location, and side. However, these differential diagnoses usually cannot explain the symptomatology of AHT as a whole. Although this explanation has the benefit of simplicity, it does not necessarily represent a true description of the underlying mechanisms. In this case, the study also revealed severe brain edema with a midline shift to the right side as well as hyperdense blood components within the anterior and posterior interhemispheric fissures. Coronal T2-weighted MR image shows bilateral subdural hygromas with a normal-appearing bridging vein (arrow) traversing the subdural hygroma on the right.

J Pediatric Neuroscience 7(1): 33-55. In addition, small and medium-sized blood vessels within the cranial cavity, particularly the bridging veins (BVs) that mainly run through the subarachnoid space, may rupture in part or completely. Its formation commences at the innermost cell layer of the dura mater cleaved by the SDC. At least 5 possibilities of interpretation, besides SDHy and SDHHy, compose nearly all time-related SDH stages from hyperacute to chronic (Table 2, lower part).22 Hence, a reliable diagnosis and age estimation of the SDC are frequently not possible without additional MR imaging and serial neuroimaging, respectively. However, some symptoms uncommonly reported include 5: The pathogenesis of subdural hygromas is not entirely understood. These would also require a harmonization of methodology and terminology as a precondition. The present review article sheds light on subdural collections in children with abusive head trauma and aims at providing a recent knowledge base for various medical disciplines involved in diagnostic procedures and legal proceedings. 2004;18 (3): 297-300. Differential diagnostics of the various SDC entities is a challenging topic for the radiologist. Lee KS. During the initial image-assessment process, the more careful labeling as SDC may be more reasonable than the possibly hasty determination of a special SDC entity.18,19 Terminology and definition criteria of the SDC entities are inconsistent, even among experts. 31 : 445-450, 1992. Missing or inadequate anamnesis—that is, no trauma reported or report of just a minor trauma despite the presence of severe brain injury. She was managed by subdural tap, bilateral craniotomy, broad-spectrum antibiotics, and subduroperitoneal shunt insertion. With respect to other variants of AHT, further features of head injury may occur, in particular, signs of blunt force (impact) trauma against the child's head such as skin lesions or skull fractures. 1999;82 (4): 155-6. History of Chronic Subdural Hematoma. The 5 patients were managed nonoperatively with acetazolamide and high-dose dexamethasone; dosages of both drugs were adjusted to the age and weight of each patient. F, SDHHy, heterogeneous variant (MR imaging, FLAIR, nonenhanced): a 4-month-old girl with wide SDCs over both frontoparietooccipital regions. A case of a nine-year-old boy, without any preceding history of trauma, is presented here who came to the emergency department of a tertiary care hospital with complaints of headache, nausea, and vomiting for the last two weeks but more for the last two days. In many cases, it is considered an epiphenomenon of head injury when it is called a traumatic subdural hygroma.Â. AJNR Am J Neuroradiol. The heterogeneous variant of the SDHHy (Fig 1E, -F) indicates 2 SDC components that coexist within the same subdural compartment (eg, above a brain convexity); these components may be clearly distinguished from one another (fluid-fluid levels possible) and may appear hyper- and hypodense during CT investigations (mixed-density pattern).22,28,30⇓–32 The hypodense component is interpretable as the following: Acute CSF collection (eg, due to an arachnoid tear, see below: “Pathophysiology”). For example, it is possible to exclude that wide hypodense SDCs with neomembranes formed 2 days ago as suggested by a witness. The SDC is composed of a thin, brain-sided, hyperdense component and a thin, dura-sided, hypodense component that runs parallel to the former component (mixed-density pattern). It is usually asymptomatic but may alter consciousness. The principle is as follows: If a stage X (eg, “chronic”) is found, according to available study data, a minimum time Y (eg, 2 weeks) has elapsed since the trauma has occurred. 1998;12 (7): 595-603. The exact etiopathogenesis is poorly understood, however, the most acknowledged mechanism suggests traumatic arachnoid tear with efflux and entrapment of CSF in the subdural space (flap valve mechanism). In the context of AHT, subdural hematoma (SDH) is described as the most common intracranial pathology in infants and toddlers.20⇓–22 SDHs, like all SDCs, may occur unilaterally or bilaterally.23 The convexities of the cerebral hemispheres (Fig 1A), the falx cerebri, the tentorium cerebelli, and the middle and posterior cranial fossae are considered typical locations.22 In many cases, SDHs have a key role as a diagnostic marker only—that is, though they may represent an important symptom of child abuse, their volumes are often small, resulting in just a minor space-occupying effect.8,21,23⇓–25 Hence, frequently, SDHs do not have a prognostic relevance for the extent of brain damage.24 Depending on the developmental stage in which subdural blood is visualized by neuroimaging, SDHs have a wide variety of appearances (Table 1). The diversity of differential diagnoses shown in Table 2 illustrates that the diagnosis of a chronic process (cSDH) may be hasty. 6. This can result from an acute tear in both the arachnoid and the dural border cell layer, resulting in communication of these two spaces. As long as no harmonization of terminology, methodology, and age diagnostic criteria of SDCs exists and as long as the scientific data situation has not improved, only rough time-related statements on SDCs will be possible. Spinal trauma such as ligamentous injuries at the craniocervical junction, or spinal sub- or epidural hematomas. Br J Neurosurg. There is no consensus for management of this complication. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. The demographics will depend on the underlying cause which includes: The vast majority of patients are asymptomatic. Arachnoid cyst of the brain is common in children but its association with spontaneous subdural hygroma is rare. Note … Management is still a matter of controversy (conservative Vssurgical) especially when consciousness is a concern. Brain Inj. In those cases, the presence of neomembranes is described after ∼2–4 weeks.22, Possible distinguishing criteria between SDHy and cSDH in neuroimaginga.

The term subdural hygroma (SDHy) is classically reserved for proteinaceous, clear, pink-tinged, or xanthochromatic collections within the subdural space containing pure CSF or at least CSF-like fluid; blood, blood products, or neomembranes are nonexistent by definition (Fig 1B, -C).22,26,27 However, the smallest amounts of blood within the SDHy cannot always be excluded and may become noticeable on CT by a slightly higher density compared with CSF (see below: “Subdural Hematohygroma,” “homogeneous variant”). A subdural hygroma is the accumulation of clear or xanthochromic CSF within the subdural space. Subdural hygromas are encountered in all age-groups but are overall most common in the elderly 7. Subdural hygromas are encountered in all age-groups but are overall most common in the elderly 7.

Thus, more reliable age-diagnostic assessments of SDCs necessitate more reference studies and special training programs, imparting specific diagnostic experiences. Of those cases, 5 pediatric patients with a delayed postoperative complication involving hydrocephalus and subdural hygromas were identified. An acute subdural hygroma results from the acute accumulation of CSF within the dural border cell layer. This can lead to leakage of CSF into the s… Note the different signal intensities and multiple fluid-fluid levels within subdural chamber formations, especially in the right occipital region. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma. Subdural hygromas refer to the accumulation of fluid in the subdural space. Today, this view has changed. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Due to shearing forces, the arachnoid membrane may also tear (eg, in the vicinity of strained BVs or at Pacchionian granulations).29,48 If this is the case, transfer of CSF from the subarachnoid space to the subdural space is possible.
