We present our experiences with computed tomography-guided stereotactic biopsy in 23 patients. The lesions were located in the cerebral hemisphere (17 cases), pons (2 cases), cerebellum (3 cases), pineal body (1 case). The histological diagnosis was made in 20 cases of 23 cases (87%), as follows ; astrocytoma in 10 cases, metastatic tumor in 7 cases, abscess in 1 case, malignant lymphoma in 1 case, radiation necros is in 1 case. There was no mortality and morbidity. Computed tomography-guided stereotactic biopsy is superior to free hand biopsy and exploratory craniotomy in the deep seated lesions and high risk patients. But, the histological diagnosis by stereotactic biopsy was different from it by open surgery in 1 case of 5 cases. To obtain a accurate histological diagnosis, we need to take biopsies from multiple target points and from new target points by reference to the histological diagnosis of frozen specimens.}, pages = {60--64}, title = {CT-guided stereotactic biopsy : 23例の経験から}, volume = {2}, year = {1989} }
