Intraosseous lipoma has a 1% incidence among the primary tumors of the bone, and it frequently occurs in the calcaneous. As it is rare, it may be mistaken for nonossifying fibroma, aneurysmal bone cyst, simple bone cyst, bone infarct and chondroid tumors Intraosseous lipomas are usually followed up conservatively due to their spontaneous involution. However, surgery is required in the presence of fracture risk, malignant transformation potential and/or extensive pain. Herein we report a case with intraosseous lipoma involving the proximal left humerus, causing cortical expansion.This presentation is unusual for this type of tumor both in terms of localization and radiology.Conventional radiography was not successful in the initial diagnosis of the condition. Advanced modalities including CT and MRI proved to have a pivotal role in diagnosis of the patient.
