This report describes the case of an asymptomatic, solitary splenotic nodule in the right ovary, revealed incidentally at histopathological examination. In gynaecological patients, splenosis most often presents as multiple pelvic nodules mimicking endometriosis. Two cases of ovarian splenosis accompanying pelvic and serosal splenotic nodules have been reported previously. However, this is the first documented case of solitary intraovarian splenosis.
