Proximal Ulna: A Rare Location for Solitary Intraosseous Hemangioma

Abstract: Intraosseous hemangiomas are rare, benign bone tumors usually affecting the bones of the axial skeleton. Its incidence in the long bones is extremely rare. We report a 19-year-old boy with solitary intraosseous hemangioma of the proximal ulna. Radiographs and computed tomography images showed a well-defined osteolytic lesion involving the right proximal ulna. Magnetic resonance imaging showed intermediate signal intensity on T1-weighted images and increased signal intensity on T2-weighted images with internal … Show more

“…Hemangioma is a rare bone lesion with a preponderance in females, with most patients being young adults and female patients younger than their male counterparts [ 2 ]. Contrary to vertebral or skull hemangiomas which are mostly asymptomatic, extremity hamgiomas are symptomatic in most patients, with local swelling or a soft tissue mass in 77% [ 2 , 4 , 12 ]. Pathological fractures are uncommon and may be the initial clinical presentation in less than 10% of patients.…”

“…Radiological presentations of hemangiomas in the long bones are highly variable and non-specific and are difficult for a correct diagnosis [ 4 ] because diverse matrix found in the bone hemangioma like vessels, fat, fibrous tissue, smooth muscles, and clotted blood may all account for the variable radiological presentations [ 13 , 14 ]. The medullary type mainly occurred at the diaphysis or metaphysis with few involvement of the epiphysis.…”

“…When found in these bones, the diagnosis is not difficult due to its typical appearance. However, it is challenging to make a firm diagnosis on imaging when IH presents in unusual locations such as a long bone [ 1 , 2 ].…”
