Aggressive intraosseous lipoma of the scapula: A case report

Abstract

The details of the pathogenesis of intraosseous lipomas are not fully elucidated, although most cases do not require surgical treatment. The present report describes the case of a 79-year-old female patient diagnosed with intracapsular lipoma who also exhibited an extraosseous extension. Chest computed tomography revealed an abnormal shadow or a mass in the right scapula and destruction of the glenoid bone. Magnetic resonance imaging revealed a high-intensity mass on T1-weighted and T2-weighted images in the same area. Marginal resection of the mass was performed. The histopathology confirmed that the mass was a lipoma. No postoperative recurrence was observed. Oncologists must be aware that lipoma arising within the scapula may extend outside the bone.

“…It manifests as regular or irregular morphology, single fat density, or mixed density areas dominated by fat on CT scan, characterized by calcification within the lesion and osteosclerosis at the edge of the lesion. Its histologic examination can show different stages of lipocyte involution but generally does not show any hematopoietic cells [ 23 ]. Fibrous dysplasia of the bone exhibits a spectrum of imaging manifestations, ranging from cystic to sclerotic and mixed patterns, typically displaying a “ground-glass” appearance.…”
