软组织血管瘤的CT诊断

CT diagnosis of soft tissue hemangioma

目的:评价CT对软组织血管瘤的诊断价值。方法:分析33例经手术病理证实或临床确诊软组织血管瘤的CT表现。结果:海绵状血管瘤18例,蔓状血管瘤8例,毛细血管瘤2例,混合型血管瘤2例,血管瘤病3例。平扫肿瘤呈结节状、分叶状、管状或团块状低密度病变,静脉石或钙化12例,增强扫描后血管成分显著强化,可呈扭曲血管状,而非血管成分不强化或轻度强化。结论:依据血管瘤的特征性CT表现,可对软组织内血管瘤作出定性诊断。

Objective: To evaluate the role of CT in the diagnosis of soft tissue hemangioma. Methods: The CT findings of 33 cases of soft tissue hemangioma proved surgical-pathologically or clinically were analyzed. Results: These tumors included cavernous(n=18), capillary(n=2), tufted(n=8), mixed (n=2) hemangiomas, and angiomatosis(n=3). All tumors in CT plain scan were tubercular, lobular, tubular or mass low-density lesions, and pleboliths or calcifications were seen in 12 cases. The vascular component within the tumor showed marked enhancement and sometimes serpentine vessels, while the non-vascular tissues showed no or light enhancement after intravenous contrast injection. Conclusion: CT can make qualitative diagnosis based on the characteristic findings of soft-tissue hemangimas.
