鞍区病变的磁共振诊断

Role of Magnetic Resonance Imaging in the Diagnosis of Lesions in the Sellar Region

目的探讨鞍区病变的磁共振诊断和鉴别诊断。方法回顾性分析142例经手术病理和临床实验室检查证实的鞍区病变磁共振图像资料,依据疾病中垂体形态的改变,将鞍区病变分为垂体瘤和非垂体类疾病,再依据疾病的组织学特点将非垂体类疾病分为囊性病变、实性病变、嚢实混合性病变。结果垂体瘤30例,非垂体类囊性病变24例、实性病变66例、嚢实混合性病变22例。结论将鞍区病变进行详细的分类,对其鉴别诊断有重要意义。

Objective To evaluate the role of magnetic resonance imaging （MRI） in the diagnosis of lesions in the sellar region. Methods The MRI data of 142 patients with surgically and pathologically proved lesions in the sellar region were retrospectively analyzed. Based on the MRI findings, the lesions were divided into pituitary adenoma and sellar region diseases except pituitary adenoma. According to the pathologic fea- tures, the sellar region diseases except pituitary adenoma were further divided into cystic lesions, parenchyma- tous lesions, and cystic and parenchymatous lesions. Results Of these 142 patients, pituitary adenoma was found in 30 cases, cystic lesions of sella region diseases except pituitary ademoma in 24. Further classification resulted in 66 cases of parenchymatous lesions and 22 cases of cystic and parenchymatous lesions. Conclusion MRI-based classification of lesions in the sellar region is useful for the diagnosis and differential diagnosis.
