A case is described in which ureteral vascular impressions called "notching" or "scalloping sign" are caused by an ureteral artery supplying a pheochromocytoma. Vascular impressions on the ureter are recognized in different conditions. Most of them are due to collateral circulation following renal artery obstruction. The differential diagnosis is discussed.
本文描述了一例输尿管血管压迹（称为“切迹”或“扇贝征”）由供应嗜铬细胞瘤的输尿管动脉引起的病例。输尿管上的血管压迹在不同情况下均可被识别。其中大多数是由于肾动脉阻塞后的侧支循环所致。文中对鉴别诊断进行了讨论。
