Angiolipomas are slow-growing, soft tissue tumors consisting of mature adipocytes and thin-walled blood vessels. While most angiolipomas are subcutaneous lesions in the trunk and upper extremities, intraosseous angiolipomas are rare at cranial site. We present the case of a 61-year-old female with an enlarging lesion in the left frontoparietal skull following minor head trauma. Radiography confirmed an expansile, enhancing, spiculated bony lesion in the left frontoparietal calvarium with extension outside the cortex into the soft tissues. She underwent a craniectomy for complete resection of the calvarial mass, which was histologically composed of mature adipocytes and disorganized blood vessels highlighted by an immunophenotype positive for S100 and CD34, respectively, consistent with a cranial intraosseous angiolipoma. The review of the literature that reported five cases of cranial intraosseous angiolipoma with our case representing the sixth case is discussed.
