【摘要】：目的探讨脾脏单发肿瘤或肿瘤样病变的CT表现。方法回顾性分析18例经手术病理证实的脾脏单发肿瘤或肿瘤样病变的临床表现及CT特点。结果 18例单发脾脏肿瘤或肿瘤样病变中,血管瘤2例,其中1例明显强化,1例边缘结节状强化;3例淋巴管瘤边缘及分隔轻度强化;3例较大窦岸细胞血管瘤动脉期明显强化,门静脉期逐渐均匀强化,延迟期强化与周围组织相仿,另2例边缘轻度强化;3例较大硬化性血管瘤结节样转化病灶内见"辐轮状钙化"及"辐轮状强化",另1例病灶内见液化坏死;1例上皮样血管内皮瘤平扫及增强无特征性改变;1例巨块型淋巴瘤动脉期可见"血管漂浮"征;2例淋巴瘤呈轻度均匀强化。结论 CT可较清晰地显示脾脏病灶的大小、形状、密度、边界及强化程度,对脾脏单发肿瘤或肿瘤性病变有较高的诊断价值。
[Abstract]:Objective to investigate the CT features of splenic single tumor or tumor-like lesions. Methods the clinical manifestations and CT features of 18 cases of splenic single tumor or tumor-like lesions confirmed by surgery and pathology were retrospectively analyzed. In tumors or tumor-like lesions, In 2 cases of hemangioma, 1 case was obviously enhanced with marginal nodular enhancement of lymphangioma, 3 cases with lymphangioma and 3 cases with large sinus cell hemangioma during arterial phase, portal vein phase was gradually enhanced evenly. The delayed phase enhancement was similar to that of surrounding tissues. In the other 2 cases, slight enhancement of the margin was seen in 3 cases of nodular transformation lesions of larger sclerosing hemangioma with "radiocalcification" and "radionuclide enhancement". In the other case, liquefaction necrosis was found in 1 case of epithelioid angioendothelioma without plain scan and enhancement. In 1 case of giant mass lymphoma, "vessel floating" sign was observed in arterial phase. Conclusion CT can clearly show the size of splenic lesions. Shape, density, boundary and enhancement are valuable for the diagnosis of single tumor or tumorous lesion of spleen.
