CALVARIAL INTRAOSSEOUS LIPOMAS :To Surgery Or Not To Surgery ?

Intraosseous lipomas (IOLs) are rare benign bone tumors,accounts for 0.1% of all bone tumors. The disease is usually asymptomatic. Hips, vertebrae, ribs may be involved. However, the IOL of the skull is less common.There is no consensus about the indications of treatment. Most of the time lesions are operated for cosmetic reasons. In the presence of neurological deficits, dura infiltration, and massive bone destruction, surgical treatment is recommended to confirm the diagnosis. It has been proposed that the excision of an asymptomatic lipoma is not necessary when the diagnosis is definite. The risk of malignant transformation in IOL is very low. We present a case with radiologic evidence highly suggestive of skull lipoma. The patient refused surgery.The patient was followed at 3-month intervals. There was no change in imaging and the patient was neurologically intact at the end of one year.
