Purpose : To analyse the MR imaging characteristics of the soft tissue hemagiomas of the extremity. Materialsand Methods : We retrospectively reviewed histopathologically proven 18 cases of hemangiomas of the extremityincluding 15 cavernous hemangiomas, 2 venous hemangiomas and 1 capillary hemangioma. The lesions were frequent infemale and low extremity. We analyzed the site, extent, margin, signal intensity , enhancement pattern, thehomogeniety of internal architecture , and abnormal vessels near the lesion. Results : The extensive lesionsinvolving multiple muscle and tissue layers were more frequent than localized lesions (12/18). Twelve cases hadill defined margins. In most cases, the lesion was heterogeneous mass composed of nodular and septal comonents.The nodular component showed intermediate signal intensity in T1WI and hign signal intensity in T2WI. The setalcomponent showed mixed inconstant signal intensity. One case of capillary hemangioma showed relatively homogeneoussignal intensity than cavernous hemangioma and the main portion of 2 venous hemangiomas had mutilple tubularsignal voids. At least some portion of the lesion was enhanced in all enhanced cases. Conclusion : The soft tissuehemangiomas of the extremity showed characteristic MR findings and MRI would be an useful method in the diagnosisof the soft tissue hemangiomas of the extremity.
