| ［摘要］ 目的 探讨多层螺旋CT（MSCT）检查对脾脏肿瘤术前诊断的价值。方法 回顾性分析26例经手术病理或穿刺活检证实的脾脏肿瘤的术前MSCT平扫及增强影像资料，探讨脾脏肿瘤MSCT影像特征。结果 26例患者中经手术病理诊断19例，经穿刺活检诊断7例。术前MSCT正确诊断21例（80.77%），误诊4例（15.38%），漏诊1例（3.85%），MSCT诊断脾脏肿瘤的灵敏度为81.0%。脾脏良性肿瘤15例，其中海绵状血管瘤4例，窦岸细胞血管瘤3例，毛细血管瘤1例，增强扫描渐进性强化的强化方式较有特点；淋巴管瘤3例，增强扫描其内分隔及周缘片絮状轻度强化，有一定特征性；错构瘤1例，为红髓型，增强扫描各期明显不均匀强化；脾脏囊肿3例，其中单纯性囊肿2例，增强扫描通常无明显强化。恶性肿瘤11例，淋巴瘤7例，增强扫描呈轻度不均匀强化；转移瘤4例，增强扫描轻中度不均匀强化。结论 MSCT检查对脾脏肿瘤的术前诊断具有较高价值。 |

| ［Abstract］ Objective To evaluate the preoperative diagnostic value of multi-slice spiral computed tomography(MSCT) in splenic tumors. Methods The MSCT plain scan and enhanced imaging data of 26 cases of splenic tumors proved by operation and pathology or puncture biopsy were retrospectively analyzed. The image features of MSCT in splenic tumors were investigated. Results Of the 26 patients, 19 cases were diagnosed by operation and pathology; 7 cases were diagnosed by puncture biopsy. 21 cases(80.77%) were correctly diagnosed by MSCT; 4 cases(15.38%) were misdiagnosed, and 1 case(3.85%) was missed. The sensitivity of MSCT was 81.0% in the diagnosis of splenic tumors. There were 15 cases of benign tumors, including 4 cases of cavernous hemangioma, 3 cases of littoral cell hemangioma, 1 case of capillary hemangioma. Hemangioma often showed progressive enhancement on contrast enhanced scan. For 3 cases of lymphangioma, capsule walls and internal septum of lymphangioma showed mild enhancement on contrast enhanced scan which was the characteristic feature of lymphangioma. 1 case of red pulp type hamartoma showed obvious inhomogeneous enhancement on contrast enhanced scans. 3 cases of splenic cyst(including 2 cases of simple cyst) showed no obvious enhancement in contrast-enhanced scan. 11 cases of malignant tumors and 7 cases of lymphoma showed mild inhomogeneous enhancement on contrast enhanced scans. 4 cases of metastatic tumors showed mild to moderate enhancement on contrast enhanced scan. Conclusion MSCT findings are of great value in the preoperative diagnosis of splenic tumors. |
