title: [A case of hemorrhage into a brain abscess].
abstract: A rare case of hemorrhage into a brain abscess in a 23-year-old man is reported. The patient complained of headache and low-grade fever on February 26, 1986. Two days later, he developed right hemiparesis and right hemisensory disturbance with mild consciousness disturbance and was admitted to a local hospital. Seven days after the onset, he suddenly became semicomatose, developed anisocoria and was consequently transferred to the University Hospital. On admission, his temperature was 37.5 degrees C and neurological examination revealed semicoma, anisocoria and right hemiparesis without nuchal rigidity. Enhanced CT scan showed a high density area within an irregular ring enhancement at the left basal ganglia. At that time, malignant glioma was diagnosed and an emergency operation was performed by left frontotemporal craniectomy. During the operation blood clot was found in the posterior part of the basal ganglia. After operation, a histological examination was made and a brain abscess was diagnosed. Gram staining revealed gram-positive bacillus. By aspiration of the abscess and chemotherapy, recovery was gradually made. He was discharged with motor dysphasia and mild right hemiparesis three months later. Differentiation between abscess and malignant glioma and the cause of the hemorrhage are discussed.
