BACKGROUND
Schwannomas in the renal hilum are rare among retroperitoneal tumors. However, the possibility of malignant findings cannot be ruled out, and surgery is often indicated. This case was expected to be difficult to remove laparoscopically because the tumor was sandwiched between the arteriovenous veins of the renal portal. Sometimes, the tumor should be resected with a conservative approach to the kidney to preserve the renal function.
CASE PRESENTATION
Our patient was a 51-year-old Asian-Japanese man who was referred to our department for a retroperitoneal tumor in the renal hilum. Since malignancy could not be ruled out due to its size (45 × 48 × 55 mm) on imaging, the tumor was excised laparoscopically. Histopathology revealed schwannoma.
CONCLUSIONS
We herein report a case in which a renal hilar tumor between renal arteriovenous vessels was successfully resected laparoscopically.
背景
肾门部的神经鞘瘤在腹膜后肿瘤中较为罕见。然而，不能排除恶性发现的可能性，因此常需要手术治疗。由于肿瘤夹在肾门的动静脉之间，本例预计难以通过腹腔镜切除。有时，为了保留肾功能，肿瘤应采用保守的方法切除。
病例介绍
我们的患者是一位 51 岁的亚洲裔日本人，因腹膜后肾门部肿瘤被转诊至我科。由于肿瘤大小（45×48×55mm）影像学提示可能为恶性，故行腹腔镜肿瘤切除术。组织病理学显示为神经鞘瘤。
结论
我们在此报告一例成功通过腹腔镜切除肾门部位于肾动静脉之间的肿瘤。
