目的：旨在描述炎性假瘤的ＣＴ表现，提高对本病诊断和鉴别诊断水平。方法：分析４０例经手术病理或临床证实的炎性假瘤ＣＴ资料。结果：４０ 例炎性假瘤有５９个区域被累及按主要受累部位分四型：眼肌型、泪腺型、球后型、混合型。炎性假瘤ＣＴ特征性表现为：（１）眼肌肥大为眼肌全程肥大（包括眼肌前部肌腱处）；（２）眼球后脂肪、眶内标志完全消失。结论：具典型ＣＴ表现，炎性假瘤诊断不难；缺乏典型ＣＴ表现，需结合临床、有时需做病理活组织检查才能诊断，并且需与其它病变相鉴别。
Objective: To describe CT manifestations of inflammatory pseudotumors, to improve the diagnosis and differential diagnosis of this disease. Methods: CT data of 40 cases of inflammatory pseudotumor confirmed by surgery or pathology were analyzed. RESULTS: Of the 40 cases of inflammatory pseudotumor, 59 were involved. The main affected areas were divided into four types: ophthalmic, lacrimal, retrobulbar, and mixed. CT features of inflammatory pseudotumor are as follows: (1) Ocular muscle hypertrophy is the whole hypertrophy of the eye muscle (including the tendon of the anterior ocular muscle); (2) The posterior fat of the eyeball and the sign of the orbit disappear completely. Conclusion: With typical CT findings, inflammatory pseudotumor diagnosis is not difficult; lack of typical CT findings, combined with clinical, and sometimes need to do pathological biopsy to diagnose, and need to be differentiated from other lesions.
