H. Yamada et al., IDIOPATHIC RETROPERITONEAL FIBROSIS WITH DUODENAL OBSTRUCTION SUCCESSFULLY TREATED WITH CORTICOSTEROIDS, Internal medicine, 37(7), 1998, pp. 592-598
We report a case of idiopathic retroperitoneal fibrosis presenting wit
h duodenal obstruction. A 55-year-old man suddenly developed severe ep
igastric pain and was admitted to our hospital. On abdominal computed
tomography (CT), a large retroperitoneal mass was found. Hypotonic duo
denography showed obstruction of the third portion of the duodenum. He
was diagnosed as idiopathic retroperitoneal fibrosis and was treated
with prednisolone, The patient improved dramatically. He has been well
for twelve months without any further treatment.
