[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.
