Surgical treatment of intracranial aneurysms: six-year experience in Belo Horizonte, MG, Brazil.

Spontaneous subarachnoid hemorrhage accounts for 5 to 10 % of all strokes, with a worldwide incidence of 10.5 / 100000 person/year, varying in individual reports from 1.1 to 96 /100000 person/year.

Chronic subdural hematoma of the posterior fossa associated with cerebellar hemorrhage: report of rare disease with MRI findings.

Chronic subdural hematoma of the posterior fossa is an uncommon entity, and spontaneous lesions are very rarely described, occurring mostly during anticoagulation therapy. The association of the posterior fossa chronic subdural hematoma with spontaneous parenchymal hemorrhage without anticoagulation therapy was never related in the literature, to our knowledge. We describe a case of a 64 year-old woman who suffered a spontaneous cerebellar hemorrhage, treated conservatively, and presented 1 month later with a chronic subdural posterior fossa hematoma.

Traumatic bilateral intraorbital (subperiosteal) hematoma associated with epidural hematoma: case report.

Extradural hematoma (EDH) is a frequent lesion, with an incidence varying from 0.2 to 6% in patients admitted to hospital due to traumatic head injury. The higher incidence is found in patients with more severe injuries.

Cauda equina hemangioblastoma: case report.

Hemangioblastomas of the spinal cord are rare lesions, and those located at the cauda equina are even rarer. Most commonly these tumors are present in patients with von Hippel-Lindau (VHL) syndrome. We describe here the case of a 48 years old woman with a pure radicular hemangioblastoma, not associated with VHL, presenting with radicular pain, diagnosed with magnetic ressonance imaging (MRI) and submitted to total resection with a very good outcome.
