Successful treatment of solitary intraosseous haemangioma of the femoral neck: a case report

Abstract

Intraosseous haemangiomas (IOHs) are benign vascular bone tumours that account for 1% of all primary bone tumours. They are most frequently seen in the vertebrae and skull, and are rarely found in long bones. Herein, we present an uncommon case of a 25-year-old woman with a solitary IOH that occupied the left femoral neck. We describe the clinical, radiological and histological details of the case, as well as the three-year outcome of the surgical treatment, which successfully preserved the femoral head. We also conducted a review of the literature on this uncommon entity.

Multifocal intraosseous hemangioma

“…The term “aggressive” refers to the presence of radiological features such as extension beyond the vertebral body, destruction of the cortex, and invasion of the epidural and paravertebral spaces. [6,8,14] Based on the radiological features, a vertebral hemangioma can be classified as typical, atypical, or aggressive. [14] In cases of compressive vertebral hemangiomas, the clinical and radiological classifications typically match because of the associations between compressive symptoms and aggressive behavior.…”

“…No recurrence was observed at 39 months of follow-up. [6] Lucia et al reported a cavernous hemangioma of the proximal femur in a young male who received en bloc resection of a tumor due to the large range of involvement and high risk of pathologic fracture. [29]…”

“…[2] These tumors are most commonly observed in the spine (30%–50%) and skull (80%), with the involvement of long and flat bones being very rare. [2–6] Intraosseous hemangiomas are rarely multifocal, being generally unifocal within a single bone or region. [7–9] Few reports have described multifocal intraosseous hemangiomas involving different parts of the human body (Table 1), [7,10,11] which vary in clinical manifestation and treatment options.…”

Displaced humeral pathological fracture secondary to intraosseous hemangioma

“…Intraosseous hemangiomas are slow progressing tumors that account for less than 1% of all bone tumors [ 1 , 2 ]. These benign vascular lesions are located in the spine and skull in 80% of cases and rarely cause any symptoms [ [1] , [2] , [3] , [4] , [5] – 6 ].…”

“…Intraosseous hemangiomas are slow progressing tumors that account for less than 1% of all bone tumors [ 1 , 2 ]. These benign vascular lesions are located in the spine and skull in 80% of cases and rarely cause any symptoms [ [1] , [2] , [3] , [4] , [5] – 6 ]. Histologically they are characterized as blood-containing, thin-walled vessels or sinuses that are lined by endothelium [7] .…”
