Abstract

Gastric metastasis from renal cell carcinoma (RCC) is extremely rare, occurring in 0.2% of all RCC cases. Owing to its low prevalence, metachronous gastric metastasis from RCC may be underdiagnosed, and the imaging findings have not been well-established. Herein we present a case of metastatic RCC manifesting as a gastric polyp in a 70-year-old female along with a literature review on the imaging findings of gastric metastases from RCC. In patients presenting with gastric hyper-enhancing polypoid masses, metastasis from RCC should be considered as a differential diagnosis.

신세포암(renal cell carcinoma; 이하 RCC)으로 인한 위전이는 매우 드물며, 모든 신세포암 사례의 0.2%에서 발생한다. 낮은 유병률로 인해 영상 소견은 아직 정확히 정립되지 않은 상태로 RCC로 인한 위전이는 영상 진단이 어려울 수 있다. 이에 저자들은 70세 여성에서 발생한 RCC의 위전이 사례와 영상 소견을 보고하고, 현재까지 보고된 문헌을 검토하여 영상 소견을 정리하였다. 위에 고조영 증강 용종이나 종괴가 새로 보이는 경우, 신세포암에 의한 전이암의 감별이 필요하다.
