An 83-year-old man with left lower back pain was found to have a 5 cm mass in contact with the right adrenal gland and a 12 mm left ureteral stone by abdominal plain computed tomography. An abdominal plain magnetic resonance imaging T2-weighted image revealed a heterogeneous high signal mass in the right adrenal gland. Pheochromocytoma, adrenal carcinoma, and retroperitoneal neurogenic tumor were suspected. Tumor markers and endocrine examinations were within standard values. Laparoscopic right adrenalectomy was performed. A 4×3.6 cm, 62 g solid tumor was found in contact with right adrenal gland. Histopathologically, hobnail-like vascular endothelial cells were found in the tumor, but no malignant findings such as multi-layered vascular endothelial cells and nuclear atypia were observed. This tumorwas diagnosed to be an anastomosing hemangioma.
一名83岁男性因左下腹疼痛就诊，腹部平扫计算机断层扫描发现其右肾上腺有一个5厘米大小的肿块，左输尿管有一颗12毫米的结石。腹部平扫磁共振成像T2加权图像显示右肾上腺有一个信号不均匀的高信号肿块。怀疑为嗜铬细胞瘤、肾上腺癌和腹膜后神经源性肿瘤。肿瘤标志物和内分泌检查均在标准值范围内。遂行腹腔镜右肾上腺切除术。术中发现一个与右肾上腺相连的4×3.6厘米、62克的实性肿瘤。组织病理学检查发现肿瘤内有鞋钉样血管内皮细胞，但未观察到多层血管内皮细胞和核异型性等恶性表现。该肿瘤被诊断为吻合性血管瘤。
