Arachnoid cyst rupture with subdural hygroma: report of three cases and literature review

Abstract Introduction. Arachnoid cysts are believed to account for about 1% of all intracranial expansive lesions, some remain inactive throughout life, others lie dormant for many years before clinical manifestation. In a few cases, arachnoid cysts have ruptured after cranial trauma or more rarely, spontaneously, with resultant subdural haemorrhage or CSF collection. Case report. We report three cases with traumatic rupture of arachnoid cyst into the subdural space in children, which is an extremely unusual complication. Discussion. A review of the literature revealed only 18 previously reported cases.

Hydrocephalus and intraspinal tumor in childhood

Hydrocephalus with spinal tumor is rare, and its cause is obscure. We report one patient with a thoracic astrocytoma who developed ventricular dilatation and intracranial hypertension. The pathophysiology is reviewed.

Acute bilateral extradural haematoma of the posterior cranial fossa

Traumatic haematomas located in the posterior fossa are less frequent than those above the tentorium. Extradural haematomas are the most common type of haematomas in the posterior fossa and are usually unilateral. We present the case of a patient with a bilateral extradural haematomas of the posterior fossa and review eight cases previously reported in the literature.

Simultaneous bilateral extradural haematoma

We report a case of acute simultaneous bilateral extradural haematoma diagnosed with computed tomography and operated on successfully.
