[Intraosseous lipoma: retrospective analysis of 19 patients].

OBJECTIVE: To investigate the diagnostic and therapeutic procedures of intraosseous lipoma.

METHODS: From June 1986 to January 2016, 19 patients with intraosseous lipoma were treated including 12 males and 7 females, aged from 24 to 76 years, a predilection aged was from 40 to 50 years in 13 cases. Symptoms presented with pain or swelling in 15 patients, the lesions were found incidentally in 3 patients, another case was bone defect lipoma replacement after curettage of bone cyst for 4 years. On plain X-ray flims of all bones showed a well-circumscribed radiolucent area. Diagnosis was established with CT or MRI. Among them, 16 cases were treated by surgical operation, 3 cases were treated by concervative treatment. All patients' clinical data, histologic findings and X-ray, CT and MRI were analysed.

RESULTS: Total 19 patients were followed up from 9 to 42 months with an average of 15 months. There was no local tumor recurrence in 16 patients after excising the tumors, the remaining 3 patients showed no enlargement of the lesion.

CONCLUSIONS: Surgical intervention is considered as an unnecessary in the patients diagnosied intraosseous lipoma by MRI or CT. Patients with symptomatic should adopt surgical treatment with curettage and bone grafting.
