Objective This study aimed to report the computed tomography (CT) and magnetic resonance imaging (MRI) findings of renal cell carcinoma associated with Xp11.2 translocation in adults.

Methods We retrospectively identified 9 adults with renal cell carcinoma associated with Xp11.2 translocation who underwent baseline cross-sectional imaging with CT (n = 9) or MRI (n = 3). All available clinical, imaging, and histopathological records were reviewed.

Results Mean patient age was 24 years (range, 18–45 years). Eight of 9 cancers demonstrated imaging findings of hemorrhage or necrosis (n = 3), advanced stage disease (n = 2), or both (n = 3) at CT or MRI.

Conclusions The possibility of renal cell carcinoma associated with Xp11.2 translocation should be considered for a renal mass seen in a patient 45 years or younger, which demonstrates hemorrhage or necrosis or advanced stage disease at CT or MRI.
