Clinical Trial
[Epidermoid cyst of the cerebellopontine angle. A surgical series of 10 cases and review of the literature].
Epidermoid cyst or cholesteastoma is a congenital slow growing lesion. It usually arises in the paramedian cisterns of the posterior fossa. Its incidence varies between 0.2 and 1% of all intracranial tumors. ⋯ A persisting neurologic deficit was observed in two cases (hearing loss, dysphonia); 4 patients were lost to follow-up. Epidermoid cyst is a benign tumor. Total resection is the ideal treatment, but we have to be aware, taking into consideration the adherence of the tumor to neurovascular structures, of the risks at attempting total resection.

Case Reports
[Image-guided epidural blood patch as effective treatment of intracranial hypotension. A case report].
We report the case of a patient with postural headache. A CT scan revealed bilateral subdural hygroma. Brain MRI showed diffuse pachymeningeal enhancement. ⋯ Conservative medical treatment was ineffective. Two thoracic epidural blood patches with radiographic control were made. We think the blood patch is the most important element for success.
