Sclerosing mesenteritis progressing to ureteral obstruction.

Sclerosing mesenteritis is part of a spectrum of benign, inflammatory diseases of the abdominal mesentery. It has been called retractile mesenteritis, and other forms include mesenteric panniculitis and mesenteric lipodystrophy. The disease rarely involves the retroperitoneum. We present a case of sclerosing mesenteritis that progressed to ureteral involvement.
