自从CT应用于临床后,颅内结核瘤的诊断已不困难。但鞍区结核瘤仍不易与鞍区其他占位性病变在术前作出鉴别诊断。我科在1988年曾收治3例鞍区结核瘤病人。 一、临床资料 例1,男,20岁。2月来双眼视力下降(左眼0.1,右眼0.4),双颞侧偏盲,双侧视神经乳头水肿。CT提示鞍区占位病变,垂体腺瘤可能性大,CT值 Since CT has been used clinically, the diagnosis of intracranial tuberculoma has not been difficult. However, saddle area tuberculoma is still not easy to make differential diagnosis with other saddle area lesions before surgery. In 1988, our department had treated 3 patients with tuberculoma in sellar area. First, clinical data Example 1, male, 20 years old. The visual acuity decreased in both eyes (0.1 in the left eye, 0.4 in the right eye), hemianopia in the bilateral temporal sacrum, and bilateral edema of the optic nerve head in February. CT suggests saddle area lesions, pituitary adenomas, CT value
