Intraosseous haemangioma Case 1Case 2Case 3 A 40-year-old patient presented with an enlarged forehead lump. Imaging showed a partially calcified avidly enhancing intraosseous lesion in the left frontal bone. An incidental lesion in the intradiploic space of the parietal bone contained fat and did not enhance (allowing for prominent nearby veins). The bone appearance was not typical, but a radiological diagnosis of a fatty haemangioma was given. A lipomatous lesion is also possible. A 70-year-old patient presented with a lump near the left zygoma. MRI showed an avidly enhancing lesion replacing part of the frontal bone without significiant avidity on FDG PET. Histopathology following resection (due to slow enlargement) confirmed a haemangioma.
