title: Intraosseous Angiolipoma of the Cranium: Case report and review of the literature.
abstract: BACKGROUND
  Angiolipomas are benign tumors that usually occur in patients during their late teens or early twenties. Most are found as multiple lesions and often located on the arm or trunk. Although predominantly subcutaneous lesions, intraosseous angiolipomas are primarily found in the mandible and ribs, with one case involving the calvarium reported in the literature.
  
  
  METHODS
  We report the case of a 55-year-old male who presented with headache, nausea, vomiting, and double vision and was found to a right frontal intraosseous lesion. He was also found to have invasive ductal breast carcinoma. The patient subsequently underwent a resection and the lesion was found to be an angiolipoma.
  
  
  CONCLUSIONS
  We report a rare case of a calvarialangiolipoma in the setting of a male with invasive ductal breast carcinoma and a review of the literature.
