Abstract:
PURPOSE: We analyzed 10 cases of intraosseous lipoma to elucidate the clinical, radiographic and pathological features, and studied the correlation between of the radiographic and pathological findings. MATERIALS AND METHODS: Ten cases of 9 patients were the subjects of this study. One patient had intraosseous lipoma in bilateral calcaneus.For the analysis of clinical features, medical records were reviewed. The simple x-ray, MRI and CT images were reviewed. The MRI examinations included T1-weighted, T2-weighted and fat-suppressed (STIR) images in all cases. Histological findings were reviewed and classified with Milgram's stage classification, and the radiographic findings also in 3 stages, and correlation of radiographic and histological stage was studied. RESULTS: The mean age of the patients was 39 years (range, 34-60 years). Seven patients were men and three were women. The meansize of the lesion was 3.4 cm (range, 2.0-5.0 cm). The most common anatomical location was calcaneus as 7 cases. Only four patients complained pain as symptom and six patients were asymptomatic. We had curettage and bone graft for the treatment. There were nolocal recurrence or malignant change during the follow up. With Milgram's classification, two cases were stage I, four were stage II and the other four were stage III. In radiographic stage, two cases were stage I, three were stage II and five were stage III. The radiographicstages were very well correlated to the histological stage. CONCLUSION: Intraosseous lipomas had characteristic radiographic and histological features according to the presenting stages, and their radiographic findings were very well correlated to the histological findings.
