We report the diagnostic utility of diffusion-weighted MR images in primary soft tissue tumors. Diffusion-weighted echo-planar imaging was performed in seventy-seven patients with primary soft tissue tumors (benign: 37 cases, malignant: 40 cases). The apparent diffusion coefficient (ADC) was determined from each image. The average ADC of benign cases was 1.53±0.26, and that of malignant soft tissue tumors was 1.31±0.63. In addition, except for three giant cell tumors of soft parts and 11 myxoid type sarcoma cases, ADC of benign soft tissue tumors was 1.58±0.19, and that of malignant soft tissue tumors was 0.94±0.19. This malignant soft tissue tumor ADC valve was significantly lower than that of the benign tumor group (p<0.0001). This indicates that diffusion-weighted imaging is useful in the differential diagnosis of primary soft tissue tumors.

We review the clinical results of 19 cases with intramuscular hemangioma. Subjects included 6 males and 13 females ranging in age from 5 to 58 years (median, 23 years). The tumor was located in the upper extremities in 3 patients, the trunk in 3, and the lower extremities in 13. Pain on motion was found in 17 patients (89.5%) and limitation in motion range was reported in 60%. Surgical planning was done using MRI and a wide surgical margin was used in regard to the affected muscle and a marginal margin for surrounding tissues. The excision was performed in all patients and no recurrence was found in the duration of follow-up ranging from 7 to 101 months (median, 57 months). Furthermore, the limitation of motion was completely improved and the postoperative disability such as gait disturbance was not noted. Thus, the wide surgical excision of intramuscular hemangioma achieved satisfactory results.
