title: Computed tomography of pseudocysts in retroperitoneal fibrosis.
abstract: Two cases of pseudocysts associated with retroperitoneal fibrosis and ureteral obstruction are described. Chemical analysis in the first case identified the retroperitoneal cyst as chylous in origin. In the second case the cystic area within the retroperitoneal fibrosis disappeared following treatment with steroids.
