“…Intraosseous lipomas are considered benign tumors, although there are rare case reports of their malignant transformation (2,3,5,6,8). At gross analysis, pale to bright yellow fat, cystic areas of fat necrosis, and variable amounts of sclerotic bone and calcified fat are commonly seen in intraosseous lipomas (6,7).…”

A 32-year-old woman with a previous diagnosis of human immunodeficiency virus infection presented to her primary care provider in 2010 with a progressively enlarging mass in her proximal right forearm. The patient reported a limited range of motion with decreased extension and, to a lesser extent, decreased flexion because of physical obstruction created by the mass. She denied experiencing pain associated with the mass. The patient reported that the area had been injured when she was assaulted with a board several years before. There was no other pertinent medical history. Imaging FindingsRadiography demonstrated a large, lytic lesion causing prominent expansile remodeling of the proximal ulna from the level of the metadiaphysis to the articular surface of the olecranon. The cortex was thin but well formed and intact (Fig 1). The lesion demonstrated trabecular thickening, coarse septa, and several well-circumscribed lucent ovoid foci with scattered peripheral internal regions of calcification but no calcified matrix suggestive of an osteoid or chondroid tumor. There was no adjacent soft-tissue mass.

“…The most common site for the development of IOL is within the long bones of the lower extremities and the calcaneus. [2][3][4][5] However, IOLs have been reported to develop at other sites, including the upper extremities (proximal radius 6 and humerus 7 ), vertebra, 8 pelvis, 9 ribs, 10,11 mandible, 12 maxilla, 13 and rarely within the bones of the skull base. Our literature search revealed 11 other case reports of IOL occurring within the skull bones, each of these being a single case report.…”
