Urinary collecting system rupture is an uncommon condition that usually occurs with symptoms of acute abdomen, secondary to peritoneal irritation by urine leaking. We report a case of a 49-year-old man admitted to our emergency department because of a worsening deep lower abdominal pain started 3 days before.The abdominal computed tomography revealed urine extravasation suggesting for urinoma. Because of patient pathological history of lymphoma, despite its apparent state of remission, he underwent a positron emission tomography - computed tomography with 18[F]-FDG and magnetic resonance in order to rule out a recurrence.Imaging supported the diagnostic hypothesis of a lymphatic recurrence that had compressed “ab-extrinseco” the urinary tract so much to break it. Based on our experience we can suggest that nontraumatic calyceal-pelvic rupture is an extremely rare manifestation of an onset of lymphoma.
