They are the result of slow bleeding over several years. The main etiology is related to the complications of the ventriculo-peritoneal shunt (VP). The purpose of this study was to recall the peculiarities and physiopathology of its pseudotumoral hematomas through 2 observations. Observation: Case 1: 8-year-old patient with a history of ventriculoperitoneal shunt at 3 months of age for congenital hydrocephalus, was admitted for functional impotence of the left-side of the body of insidious onset spreading over 9 months in a chronic headache, blurred vision and generalized seizure. CT scan showed a heterogeneous subdural hematoma of the right frontoparietal with calcifications. The patient underwent an excision by morcellation of a yellowish, friable partly calcific mass. The postoperative history was marked by a total recovery of the neurological deficit. There was no recurrence at 6 months postoperatively. Case 2: 11-year-old adolescent, treated with VP shunt at 6 months of age for post-meningitic hydrocephalus, was admitted for helmet headache, dizziness, lightheadedness and apathy progressing for 3 years. CT scan showed hypodensity of right peri-hemisphere with calcified linings, exerting a mass effect on the medial structures. The patient was given a block excision of a calcific mass with blood content. The evolution was marked by the complete resolution of seizures and hemiparesis. There was no recurrence at 6 months postoperatively. Conclusion: Calcified subdural hematomas are rare and consecutive to the complications of VPS. The clinical signs are those of a benign brain tumor. Treatment is dominated by the difficulties of cerebral reexpression.展开更多

Vourc’h in 1963. It manifests encouraging prospects in control of refractory intracranial hypertension, prevention of complications secondary to aneurysmal subarachnoid hemorrhage, prediction of shunt respondency in normal pressure hydrocephalus, management of cerebrospinal fluid (CSF) leakage, and application in bacterial meningitis and ventriculitis. But many questions on the efficacy and safety of ELD are remained to be answered by future studies. CSF overdrainage and ELD-related meningitis are the two most common and fatal complications due to inappropriate usage of ELD. Randomized control ed trials are badly in need to more safely and rational y guide the clinical application of ELD.展开更多
