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.
虽然大多数骨内脂肪瘤病例不需要手术治疗，但其发病机制的细节尚未完全阐明。本报告描述了一例79岁女性患者，诊断为囊内脂肪瘤，同时伴有骨外扩展。胸部计算机断层扫描显示右肩胛骨有异常阴影或肿块，肩胛盂骨破坏。磁共振成像显示同一区域在T1加权和T2加权图像上有高强度肿块。对肿块进行了边缘切除。组织病理学证实该肿块为脂肪瘤。未观察到术后复发。肿瘤学家必须意识到，起源于肩胛骨内的脂肪瘤可能会延伸至骨外。
