Case ReportsPure amnesia caused by bilateral temporal lobe astrocytoma--case report.
A 32-year-old male presented with progressive pure amnesia caused by astrocytoma invading the bilateral medial temporal lobes. Methionine positron emission tomography demonstrated the extent of tumor invasion well. His memory impairment was partially improved by treatment for the astrocytoma. Lesion of the bilateral hippocampus causes memory impairment, but pure memory loss without other associated neurological sign or deterioration of consciousness is rare in a case of cerebral neoplasm.

Acute subdural hematoma without subarachnoid hemorrhage due to ruptured intracranial aneurysm--case report.
A 54-year-old female presented with acute subdural hematoma secondary to rupture of an intracranial aneurysm. She was admitted with acute onset of severe headache, nausea, and vomiting. There was no past history of head trauma. ⋯ Angiography revealed an aneurysm of the internal carotid-posterior communicating artery which was oriented posterolaterally. Uneventful clipping was performed and the patient was discharged from hospital without neurological deficits. The possibility of aneurysmal subdural hematoma should be considered in the absence of trauma.
