作者报告2例罕见的鞍内鞍隔下脑膜瘤.例1、64岁妇女,表现为短暂性脑缺血发作。神经学检查、眼科检查和内分泌试验均正常。颅骨平片和蝶鞍断层显示鞍底轻度变薄,伴鞍内钙化。CT增强扫描显示一均匀的鞍内和鞍上占位。双侧颈内动脉造影提示鞍内肿瘤染色伴小的鞍上侵犯。放射性核素脑扫描证实鞍内和鞍上的病变。经右额下入路手术,发现鞍内肿瘤,推移鞍隔。视神经较长,视交叉后置可能是无视野缺损的原因。活检诊断为脑膜瘤。为保护垂体腺,手术仅作部分切除。术后无特殊,18个月后仍无临床变化。例2、男性,56岁,因视野缺损和垂体功能衰 The authors report two rare cases of intracranial submandibular meningiomas. Case 1, 64-year-old woman presented with transient ischemic attack. Neurological tests, ophthalmic tests, and endocrine tests were all normal. Skull flats and sella showed a slight thinning of the saddle base with calcification within the saddle. The CT-enhanced scan showed a uniform saddle and suprasellar position. Bilateral internal carotid artery angiography suggested intracranial tumor staining with small suprasellar invasion. Radionuclide brain scans confirmed intra-and intra-saddle lesions. After the right subfrontal approach surgery, intrasellar tumors were found and saddle septae were removed. Long optic nerves, posterior optic chiasm may be the cause of no visual field defect. Biopsy was diagnosed as meningioma. In order to protect the pituitary gland, surgery is only partially removed. No special postoperative period, no clinical changes after 18 months. Case 2, male, 56 years old, due to visual field defect and pituitary dysfunction
