Twenty patients with intracranial medulloblastoma were analyzed by CT. All patients presented with symptoms of headache, and in eight clinical findings consistent with intracranial hypertension were the only neurological abnormalities. In 16 cases, the medulloblastoma appeared as midline posterior fossa mass and in four cases it was located laterally in the cerebellar hemisphere. The fourth ventricle appeared abnormal and there was evidence of obstructive hydrocephalus in all cases. The lesion was hyperdense in 14 cases but in only one was there evidence of calcification; the neoplasm appeared isodense in six. Post-contrast enhancement was visualized in all cases; this was homogeneous in 18 and had a ring-pattern of variable thickness in two others.
对20例颅内髓母细胞瘤患者进行了CT分析。所有患者均有头痛症状，其中8例仅有符合颅内高压的临床表现，为唯一的神经功能异常。16例中，髓母细胞瘤表现为后颅窝中线肿块，4例位于小脑半球外侧。第四脑室均出现异常，所有病例均有梗阻性脑积水的证据。14例病变呈高密度，但仅1例有钙化证据；6例肿瘤呈等密度。所有病例均可见对比剂增强后强化；18例强化均匀，另2例呈厚度不一的环形强化。
