Abstract :The case of an 11-year-old boy with astrocytoma diagnosed by stereotaxic biopsy is presented. He visited our outpatient clinic because of right hemiparesis. CT scan showed a calcified mass (8×11×lOmm) at the left globus pallidus without mass effect. Arlgiogram reveaIed no abnormal findings, Two years later, CT scan revealed enlargement of the calcified mass (11×11×15mm) and enhancement effect around the basal ganglia. In MRI, a conglomerate of low intensity by T_1-weighted imaging and of high intensity by T_2-weighted imaging was shown. Under suspicion of deep-seated brain tumor, stereotaxic biopsy was performed. Five pieces of specimen(1×2mm) were taken out of the caudate nucleus and putamen by a fine spiral needle and evaluated histologically. Diagnosis was made as astrocytoma gradeII. For such a deep tumor in the cerebral hemispheric or basal ganglion, a biopsy can be safely taken with a needle using a CT-guided stereotaxic technique.
