BACKGROUND Subdural posttraumatic collections are called usually Traumatic Subdural Hygroma (TSH). TSH is an accumulation of cerebrospinal fluid (CSF) in the subdural space after head injury. These collections have also been called Traumatic Subdural Effusion (TSE) or External Hydrocephalous (EHP) according to liquid composition, or image features. There is no agreement about the pathogenesis o...

OBJECTIVE Traumatic brain injury (TBI) in children under age 24 months has characteristic features because the brain at this age is rapidly growing and sutures are opened. Moreover, children this age are completely dependent on their parents. We analyzed the demographic data and risk factors for outcomes in TBI patients in this age group to elucidate their clinical characteristics. METHODS We...

Acute subdural hematoma (ASDH), chronic subdural hematoma (CSDH) and subdural hygroma (SDG) occur in the subdural space, usually after trauma. We tried to find a certain relationship among these three traumatic subdural lesions in 436 consecutive patients. We included all subdural lesions regardless of whether they were main or not. We evaluated the distribution, age incidence and interval from...

Fifty-one cases with subdural hygroma experienced in the past 20 years were retrospectively reviewed. Eight patients showed definite ventricular dilation differing from simple restoration of the ventricles following disappearance of the cavity. The mean age was 72.4 years. Six patients presented with mental change as the initial symptom. On the initial computed tomography (CT), 75% of the cases...

Bulging of a hemicranium and thinning of the temporal bone are encountered in some space-occupying processes, of neoplastic, or parasitic origin, in subdural hygromas, in infantile encephalopathies, etc., and always require supplementary investigations for their discovery and adequate surgical solution. In hygromas, there is a scarcity of neurological signs, and a slightly delayed psychical dev...

THE formation of cranial subdural hematomas after lumbar puncture is a well-known complication of spinal anesthesia, although rare in young patients. Pathogenesis of this condition has been related to rupture of bridging veins joining the cerebral surface and the dura mater. The precipitating event in these cases is the continuous leakage of cerebrospinal fluid through the dural hole. More unus...

Intracranial arachnoid cysts are congenital collections of fluid that develop within the arachnoid membrane because of splitting or duplication of this structure. It corresponds to 1% of all non-traumatic intracranial mass lesions. Arachnoid cysts...
