A managed case of rare intraosseous lipoma of femoral neck.

43 year-old female presented with anterior hip pain not responding to conservative treatments. Plain radiograph showed radio-lucent area with sclerotic margin in the femoral neck region. On MRI scan the diagnosis of intraosseous lipoma was confirmed. Due to persistent pain and risk of fracture, decision of operative treatment was made. She underwent curettage of the lesion under image-intensifier and reinforcement of femoral neck with non-vascularised fibular grafting. Post-operative x-rays showed incorporation of the fibular graft with good clinical and functional outcome. Intraosseous lipoma in the femoral neck is a rare presentation and in cases with persistent symptoms or risk of impending fracture, operative treatment gives a good functional outcome.
