Imaging features of intraosseous hemangiomas: beyond the mobile spine and calvarium

Hemangioma of the Ilium Simulating Bone Metastasis on 18F-PSMA-1007 PET/CT

“…The lesion (arrowheads) measuring 1.4 cm in maximum diameter showed hyperintensity on axial fat-suppressed T2-weighted image (A), hypointensity on coronal T1-weighted image (B), and marked enhancement on postcontrast axial (C) and coronal (D) fat-suppressed T1-weighted images. The imaging appearances and stability in size of the left iliac bone lesion were consistent with hemangioma 1,2. Osseous hemangiomas are benign vascular tumors, which are usually asymptomatic and discovered incidentally on imaging 3,4.…”

“…Osseous hemangiomas are most commonly seen in the spine and skull, and less frequently affect the appendicular skeleton. Hemangioma of the ilium is rare 1,2,5,6 . There are a few case reports of 68 Ga-PSMA uptake in vertebral 7–9 and skull 10 hemangiomas, which may be due to PSMA expression in endothelial cells.…”

“…Hemangioma of the ilium is rare. 1,2,5,6 There are a few case reports of 68 Ga-PSMA uptake in vertebral [7][8][9] and skull 10 hemangiomas, which may be due to PSMA expression in endothelial cells. Lowto-moderate PSMA uptake has been shown in many other benign bone lesions, including osteophyte, 11 Schmorl node, 12 fracture, 13 osteoid osteoma, 14 Paget disease, 15 fibrous dysplasia, 16 and infection.…”
