PURPOSE Posterior fossa epidural hematomas are much less common than supratentorial epidural hematomas. The incidence of posterior fossa epidural hematomas among intracranial epidural hematomas has been reported to be 4% to 7%. Seven cases of posttraumatic posterior fossa epidural hematomas diagnosed by computed tomography (CT) are reported with radiological and clinical findings. MATERIALS A...

Objective and importance: Cerebral supra or infratentorial tumors associated with chronic intracranial hypertension and hydrocephalus may rarely generate spontaneous, non-traumatic rhinorrhea. We report one case of this rare condition with a giant atypical left posterior fossa meningioma and right nostril rhinorrhea. Clinical presentation: A 55-years-old woman was admitted for a 16-year history...

OBJECTIVE To determine the incidence and risk factors for leptomeningeal metastasis after surgery for brain metastasis of solid tumors. METHODS Review of the records of all patients operated on for brain metastasis between January 1990 and August 1995. RESULTS In this period 28 patients underwent surgery for brain metastasis, of whom 27 were available for evaluation in this study. Median su...

PURPOSE To characterize the MR findings of glioblastoma multiforme in the posterior fossa. METHODS MR studies of nine patients with surgically proved posterior fossa glioblastoma multiforme were retrospectively evaluated. MR characteristics studied included tumor location, signal intensity, enhancement pattern, and presence of intratumoral hemorrhage, as well as presence of secondary hydrocep...
