title: [Pain in the side].
abstract: In a 54-year-old patient who entered the hospital because of flank pain of the left side, a prevesicular urethral calculus was found. On further investigation hypercalcaemia and hypophosphataemia were detected, possibly indicating hyperparathyroidism. When an ultrasound of the abdomen was made to exclude hydronephrosis, a tumor in the pancreas was found. The result of the fine needle biopsy of this tumor showed a neuroendocrine tumor. The examination of neuroendocrine parameters was without any reference to an active secreting process. On suspicion of a multiple endocrine neoplasia, a MRI of the hypophysis was made which showed no adenomatous alterations. The examination of the neuroendocrine parameters were without any reference to an active secreting process of the hypophysis, too.
