胼胝体病变的临床与CT、MRI表现

Clinical CT and MRI of the Corpus Callosum Disorders

目的：分析胼胝体病变临床表现及CT、MRI影像学特征。材料与方法：搜集经CT、MRI检查后发现胼胝体病变37例（其中15例经手术及定向穿刺后病理证实）。结果与结论：37例胼胝体病变包括所胼胝体发育不全6例、脂肪瘤5例，外伤及脑血管意外致血肿11例、肿瘤13例（胶质母细胞瘤3例、Ⅰ～Ⅱ级星形细胞瘤5例、淋巴瘤3例、转移后2例）、血管畸形及多发性硬化各1例。除8例脑外伤以外，其他病人临床上均有长期头晕、头痛、突发意识障碍、癫痫等表现、但非特征性改变。CT、MRI对胼胝体病变（无论是原发或是继发）的发现、诊断及鉴别诊断均有重要的价值，MRI在定位上较CT更为精确．从而为术前手术方式的选择，术后放疗的定位准确提供更多有用信息。

To analysis the clinical appearance, CT and MRI of the corpus callosum disorders. Material and Methods:37 patients with corpus callosum disords found by CT and MRI(among those, 15 cases confirmed by operation and stereotatic biopsy). Results and conclusions:37 patients with corpus callosum disorders, including dysplasia(6), lipomas(5), Hematomas(11), glioblastomas (30, astrocytpmas(1～2 grade, 5), lymphomas(3), and metastases(2), arterovenous malformation(1) multiple sclerosis(1). Most patients manifested the clinical behavior of chronic dizziness, headache, sudden unconsciousness,epilepsia, except for 8patients with head injury. but there were no specificires. It was the most important to find, diaglnosis and differential diagnosis on corpus callosum disorders(whether Peimary or secondary) by CT and MRI. And more accurate location on MRI.
