Angiolipoma is a type of lipoma, a benign soft tissue tumor. It is distinguished by the excessive degree of vascular proliferation and the presence of mature adipocytes. It occurs commonly on the trunk and extremities. Angiolipomas larger than 4 cm are classified as "giant," and due to their size, histological evaluation is necessary to exclude malignancy. We report a case of a male patient who suffered from a giant noninfiltrating intramuscular angiolipoma which formed after venipuncture in the antecubital fossa. Clinical examination showed a palpable painless soft mass. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a giant angiolipoma on the right forearm. Surgical removal of the mass was performed, and the biopsy was negative for malignancy. To the best of our knowledge, this is the first report in the literature of posttraumatic intramuscular angiolipoma. Physicians and orthopedic/general surgeons should be aware of the possibility of soft tissue masses in a posttrauma situation.
血管脂肪瘤是脂肪瘤的一种，脂肪瘤是一种良性软组织肿瘤。它的特征是血管增生过度且存在成熟的脂肪细胞。它常见于躯干和四肢。直径大于4厘米的血管脂肪瘤被归类为“巨大型”，由于其大小，需要进行组织学评估以排除恶性肿瘤。我们报告一例男性患者，他患有巨大的非浸润性肌内血管脂肪瘤，该肿瘤在肘前窝静脉穿刺后形成。临床检查显示可触及无痛性软肿块。计算机断层扫描（CT）和磁共振成像（MRI）显示右前臂有一个巨大的血管脂肪瘤。对肿块进行了手术切除，活检结果为恶性阴性。据我们所知，这是文献中关于创伤后肌内血管脂肪瘤的首例报告。医生以及骨科/普通外科医生应意识到创伤后出现软组织肿块的可能性。
