Radiologic and pathologic characteristics of the WDHA syndrome.

Abstract

A case of a non-beta islet cell tumor of the pancreas that produced the WDHA (watery diarrhea, hypokalemia, and achlorhydria) syndrome is presented. An enlarged body-tail region of the pancreas is demonstrated on transaxial views; multiple fluid-filled loops of small and large bowel are also noted. The angiography of the tumor is similar to other non-beta islet cell lesions consisting of a large hypervascular mass with hypertrophied feeding vessels and a persistent, dense capillary stain. The demonstration of elevated levels of vasoactive intestinal polypeptide in both tumor and plasma and the ultrastructural description of endocrine granules may help to explain the pathophysiology in this case.
