摘要
目的探讨MRI对软组织肿瘤的诊断价值。方法回顾性分析2002--2006年经手术病理或穿刺证实的软组织肿瘤160例的MRI资料，男98例，女62例；年龄3～75岁，平均32岁；临床均以软组织肿胀、肿块伴或不伴疼痛为主要征象。采用Phlips Gyroscan Intera 15Tmaster MR机，表面线圈、E线圈、C1线圈，采用快速自旋回波序引，脂肪抑制序列，矢状位、冠状位及横断位扫描及增强扫描，160例软组织肿瘤中，良性120例，其中脂肪瘤30例，肌肉血管瘤25例。腱鞘巨细胞瘤30例，神经源性肿瘤20例。硬纤维瘤15例；软组织恶性肿瘤40例，其中脂肪肉瘤16例，恶性纤维组织细胞瘤11例，平滑肌肉瘤6例，纤维肉瘤3例，淋巴瘤2例，黑色素瘤2例。结果良性肿瘤直径为1-16cm，边缘光滑、规则，信号均匀，增强均匀强化或不强化；恶性肿瘤直径5～12cm，形态不规则，多呈分叶状，信号不均匀，累及周围结构，强化明显且不均匀。结论MRI对软组织肿瘤检查敏感性高，肿瘤的发病部位及某些特征有助于诊断及鉴别诊断，对脂肪瘤及黑色素瘤的诊断有特异性。
Objective To investigate the diagnostic value of magnetic resonance imaging （MRI） in the tumor of soft tissue. Methods A total of 160 patients [98 males and 62 females; mean age 32 years （age range 3 -75） ] with soft tissue tumor confirmed by pathological findings were admitted to the hospital from the year of 2002 to 2007. The main clinical manifestations were soft tis- sue swelling and mass with or without pain. All the patient were examed with MRI （ Philips Gyroscan Intera 15Tmaster） , Surface Coil, E Coil and CI Coil. MRI examination was performed by Fast spin echo （FSE） sequences, fat inhibition sequences, and coronal, sagittal and axial planes. Of the 160 cases, there were 30 with lipoma, 25 with muscle vascular tumor, 30 with giant cell tumor of tendon sheath, 20 with neural tumor, 15 with fibrous tumor and 40 with malignant tumor including 16 with liposarcoma, 11 with malignant fibrous histiocytoma, 6 with leiomyosarcoma, 3 with fibrosarc0mas, 2 with lymphoma and 2 with melanoma. Results The benign tumors was 1 - 16 em in diameter, and smooth and regular in shape, with a homogeneous density with uniform enhancement or without cnhancement. The malignant tumors was 5 - 12 cm in diameter, and irregular and lobular in shape, with heterogeneous density, peritumor infiltration and obvious and heterogeneous enhancement. Conclusion MRI is highly sensitive to soft tissue tumors. The location and some characteristic signs are helpful for diagnosis and differentiation, especially for the diagnosis of lipoma and melanoma.
