Abstract

Acute upper gastrointestinal bleeding (UGIB) is a medical emergency with most common cause being peptic ulcer disease (PUD) or variceal bleeding. However, cancers that cause UGIB by invading the small intestine are uncommon, and the invasion of renal cell carcinoma (RCC) into the duodenum is an even rarer occurrence. A 55-year-old male presented with melena and right flank pain. Esophagogastroduodenoscopy (EGD) revealed an active bleeding source in the duodenum, later identified on contrast-enhanced computed tomography (CECT) as a duodenorenal fistula (DRF) caused by direct extension of the RCC. The imaging confirmed the presence of a malignant renal mass infiltrating adjacent organs. This atypical presentation of RCC with DRF manifesting as UGIB underscores the importance of comprehensive evaluations in cases of gastrointestinal bleeding to identify rare underlying causes.

伪装成急性上消化道出血的肾细胞癌
急性上消化道出血(UGIB)是一种医疗急症,最常见的病因是消化性溃疡病(PUD)或静脉曲张出血。然而,通过侵犯小肠引起 UGIB 的癌症并不常见,而肾细胞癌(RCC)侵犯十二指肠的情况更是罕见。一名 55 岁的男性患者出现血便和右侧腹痛。食管胃十二指肠镜检查(EGD)发现十二指肠内有活动性出血源,后经造影剂增强计算机断层扫描(CECT)确定为 RCC 直接延伸引起的十二指肠瘘(DRF)。影像学检查证实存在浸润邻近器官的恶性肾肿块。这种RCC伴有DRF并表现为UGIB的非典型表现强调了对消化道出血病例进行全面评估以确定罕见潜在病因的重要性。
