Three treated groups totaling 60 patients with solitary bone cysts were evaluated. Curettage and bone graft, methylprednisolone acetate (MPA) injection, and curettagehydroxyapatite (HA) filling were performed in 20, 32, and 12 patients, respectively. Four patients were treated with two different interventions. The healing rates (complete healing plus incomplete healing evaluated by Campanacci's criteria) in the three groups was 85%, 83%, and 100%, respectively. Although the healing rate of HA filling appeared to be best in this series, the average duration of follow-up was less than two years. Therefore, MPA injection should be the preferred method for its greater simplicity and the absence of complications.

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.
