Abstract

Renal myxomas are very rare benign tumors. To date, a few cases have been reported in English literature, mostly in pathology and urology journals. Thus, there are few reports on the radiological findings associated with renal myxomas. We report on the imaging findings in a case of renal myxoma in a 62-year-old male. MRI demonstrated a well-defined mass in the left renal sinus, with intermediate high signal intensity on T2-weighted images and low signal intensity on T1-weighted images. The tumor showed gradual enhancement on contrast-enhanced T1-weighted images.

신장 점액종은 신장에서 발생하는 드문 양성 종양이다. 최근까지 영미권에서 적은 수의 증례 보고가 되어 있으나 대부분의 경우 비뇨의학적 혹은 병리학적으로 접근하여 점액종의 영상의학적 소견은 잘 분석되지 않았다. 우리는 62세 남자 환자에서 발생한 신장 점액종의 영상 소견을 보고하고자 한다. 해당 종양은 좌측 신장동에 위치하고 있었으며, 자기공명영상의 T2 강조영상에서는 중등도의 고신호강도로 T1 강조영상에서는 저신호강도로 보였다. 또한 종양은 역동적 조영증강 영상에서는 점진적인 조영증강을 보였다.
