Right ventricular blood cyst in an adult autosomal dominant polycystic kidney disease patient: an unusual association

Blood cysts of the heart are unusual primary cardiac tumor-like masses, which are usually located on the cardiac valves. These are very rare in adults, especially in a non-valvular location. Autosomal-dominant polycystic kidney disease (ADPKD) typically presents with multiple bilateral renal cysts, resulting in chronic kidney disease. Whilst many of the extra-renal manifestations of ADPKD are well-documented, associated cardiac masses are extremely rare: and cardiac blood cyst has not been reported in a patient with APKD to date. We present a 57-year man with a history of ADPKD and end-stage renal disease with a 2-cm-diameter right ventricular blood cyst, which was detected on multimodality imaging. (author)
