Discontinuous splenogonadal fusion in a patient with left testicular mass

Abstract

Purpose. Splenogonadal fusion (SGF) is a benign congenital anomaly that occurs predominantly in males and presents clinically as a testicular lump which is com-prised of normal splenic tissue. There are two types of SGF: Continuous and discon-tinuous. In continuous SGF, a fibrous band of splenic tissue is found between the spleen and testis and can be easily recognized on imaging studies. Conversely, diagnosis of discon-tinuous SGF is far from straightforward: If misdiagnosed, it leads to unnecessary orchiecto-my in about a third of reported cases. We report a case of discontinuous SGF which was diagnosed postoperatively in a pa-tient with left testicular mass. We also provide a comprehensive review of imaging features and differential diagnosis of discontinuous SGF.
