目的:探讨泪腺多形性腺瘤的CT诊断价值。方法:回顾分析16例(良性12例,恶性4例)经病理证实的泪腺多形性腺瘤的临床资料和CT表现。结果:泪腺多形性腺瘤CT表现为眶外上方泪腺区肿块,良性多形性腺瘤呈圆形或类圆形高密度块影,边界清,光滑;密度均匀;泪腺窝骨壁可有压迫性改变;偶有局部眶壁骨质缺损。恶性多形性腺瘤边界不清或形态不规则;密度不均;局部骨质破坏;可有周围浸润。结论:CT扫描对泪腺多形性腺瘤具有较大的诊断价值,应作为首选检查。
Objective: To explore the value of CT diagnosis of lacrimal gland pleomorphic adenoma. Methods: The clinical data and CT findings of 16 cases (benign 12 cases, malignant 4 cases) pathologically confirmed lacrimal gland adenoma were retrospectively analyzed. Results: The lacrimal gland pleomorphic adenoma CT showed lacrimal gland mass above the orbit, the benign pleomorphic adenoma was round or round high-density block, the boundary was clear and smooth; the density was uniform; Change; occasionally partial orbital bone defects. Malignant pleomorphic adenoma border is unclear or irregular in shape; uneven density; local bone destruction; may have infiltration around. Conclusion: CT scan has great diagnostic value for lacrimal gland pleomorphic adenoma and should be the first choice of examination.
