Intramuscular Hemangioma

Intramuscular hemangioma (IMH) is a relatively are tumor. Preoperative misdiagnosis is common. From 1984 to 1993, 13 patients with IMHs were treated sur-gically, 7 males and 6 females. The mean age at surgery was 21.3 years. 4 cases had trauma histories. Main signs and symptoms were mass, pain, tenderness, functional impairment and anatomic deformity. Preoperative diagnostic studies included plain radiographies, CAT scannings, angiographies, xerographies, whole body bone scannings and MR imaging, 2 intralesional excisions, 4 marginal excisions and 7 wide excisions with or without vascular pedicle ligations (VPL) were performed. Complica-tions were 1 skin edge necrosis with hematoma formation and 3 recurrences. 2 recur-rent cases received reoperations. The preoperative accurate diagnosis rate was 54%. CAT scan, MR image and angiogram had great help for accurate diagnosis, surgical planning and vascular pedicle identification. Big and strong muscles were commonly invaded, especially quadriceps femoris. Phleboliths or calcifications were more fre-quently to be found in cavernous and venous type lesion. Most common pathological pattern was cavernous type. Mixed type lesion had a higher recurrent tendency, and so as intralesional excision procedure. Functional evaluation rating system was used, mean rating percentage was 91.3%, ranged from 37 to 100%. 11 cases had more than 90 functional percentage. Mean follow-up period was 47 months.
