“…The CT scan demonstration of intraosseous lipomas consists of a lytic lesion with distinct borders and a negative Hounsfield unit parallel to the adipose tissue. While irregularity of the bone cortex and marginal sclerosis surrounding the lesion are commonly observed [10]. Intraosseous lipoma presents on MRI as a lesion with a high signal intensity lesion on both T1 and T2weighted images identical to that of adipose tissue that allows differentiation from other bone lesions [10].…”

Introduction: Intraosseous lipoma is an extremely rare lesion that represents no more than 0.1% of all bone tumors. It is often misdiagnosed, unlike other benign bone lesions. With the combination of radiography, computed tomography (CT) and magnetic resonance imaging (MRI), the diagnosis can be done without histological confirmation.Case Report: A 42-year-old man presented with a history of progressive left femoral pain radiating to his buttock and benefited from plain radiographs of the left hip showed a lytic lesion containing a central calcification and surrounded by sclerotic margins in the intertrochanteric region of the proximal femur. The patient underwent further evaluation with CT and MRI. Based on the results to the MRI and CT scan, intraosseous lipoma was confirmed and the need for further diagnostic tests has been eliminated. Conclusion:We reported a rare case of symptomatic intraosseous lipoma of the femoral bone, which was difficult to diagnose on only plain radiographs. This showed the interest of MRI in the elimination of differential diagnosis and the confirmation of intraosseous lipoma.

Introduction:Intraosseous lipoma is a rare benign bone disease. Long and cancellous bones are the most locationsthat can be affected. Almost all lesions were discovered incidentally on imaging modalities that were done during an unrelated investigation. As it is rare, it may be mistaken for nonossifying fibroma, aneurismal bone cyst, simple bone cyst, bone infarct or chondroid tumors. Recently with the high quality imaging modalities such as CT scan and/or MR imaging, the diagnosis of intramedullary lipoma and some other bone lesions can be done without the need for bone biopsy and surgery.Case Report:We’re reporting a rare case of intraosseous lipoma of the distal femur. Plain film radiography showed barely visible medullary expansion and lucency in the distal left femoral diaphysis. The patient underwent further evaluation with computed tomographic (CT) and magnetic resonance Imaging (MRI). According to the MRI and CT scan findings, intraosseous lipoma was confirmed and the need for more diagnostic tests were eliminated.Conclusion:Although Intraosseous lipoma doesn’t have any manifestations clinically but it should be considered in the differential diagnosis of bone pains. MRI has an important role in characterization of soft tissue and bone marrow lesions therefore non-surgical approach for most of the patients with intraosseous lipoma would be beneficial.
