目的:分析垂体脓肿的MRI表现,以提高垂体脓肿诊断的准确性。材料与方法:对经过手术及临床治疗确诊的6例垂体脓肿的MRI资料并结合文献,进行回顾性分析。结果:6例垂体均增大,垂体高度0.9cm-3.3cm不等,6例中,病灶内部T1WI呈等信号2例,稍低信号1例,等、稍低混杂密度2例,1例呈高信号。T2WI呈高信号1例,稍高信号2例,等信号1例,2例信号表现不均匀,以高信号为主。6例均呈周边环形强化,强化环厚约0.2cm-0.4cm,2例呈多房表现。结论:MRI增强检查对垂体脓肿的诊断及鉴别具有重要意义。
Objective: To analyze the MRI findings of pituitary abscess to improve the diagnostic accuracy of pituitary abscess. Materials and Methods: The MRI data of 6 cases of pituitary abscess confirmed by operation and clinical treatment were retrospectively analyzed. Results: 6 cases of pituitary gland increased, pituitary height of 0.9cm-3.3cm range, 6 cases, T1WI lesions were iso-signal in 2 cases, slightly lower signal in 1 case, and so on, slightly lower hybrid density in 2 cases, 1 case High signal. T2WI showed high signal in 1 case, slightly higher signal in 2 cases, equal signal in 1 case, 2 cases of non-uniform signal, with high signal-based. 6 cases showed circumferential ring enhancement, enhanced ring thickness of about 0.2cm-0.4cm, 2 cases showed multi-room performance. Conclusion: MRI enhanced examination of pituitary abscess diagnosis and identification of great significance.
