Approximately 100 cases of polyorchidism have been reported in the literature. Management remains controversial especially if there is no associated abnormality identified. We report a case of triorchidism confirmed by magnetic resonance imaging (MRI). The patient has been managed conservatively and remains under regular radiological follow-up with MRI.

IntroductionPeutz-Jeghers syndrome (PJS) is a rare familial disorder characterised by mucocutaneous pigmentation, gastrointestinal and extragastrointestinal hamartomatous polyps and an increased risk of malignancy. Peutz-Jeghers polyps in the bowel may result in intussusception. This complication usually manifests with abdominal pain and signs of intestinal obstruction.Case PresentationWe report the case of a 24-year-old Caucasian male who presented with melaena. Pigmentation of the buccal mucosa was noted but he was pain-free and examination of the abdomen was unremarkable. Upper gastrointestinal endoscopy revealed multiple polyps. An urgent abdominal computed tomography (CT) scan revealed multiple small bowel intussusceptions. Laparotomy was undertaken on our patient, reducing the intussusceptions and removing the polyps by enterotomies. Bowel resection was not needed.ConclusionMelaena in PJS needs to be urgently investigated through a CT scan even in the absence of abdominal pain and when clinical examination of the abdomen shows normal findings. Although rare, the underlying cause could be intussusception, which if missed could result in grave consequences.

This case report describes a patient in whom echocardiography showed borderline left ventricular hypertrophy and a mass adjacent to the right atrial wall. This naturally caused some concern as the differential diagnoses included that of a right atrial myxoma and further investigations were organised. A subsequent cardiac MRI revealed this thickening to be a prominent crista terminalis. The crista terminalis is a variant of normal anatomical structures within the right atrium, which mimics an atrial mass.
