[Isolated mesenteric fibromatosis].

Isolated mesenteric fibromatosis is a rare form from the group of intraabdominal fibromatoses which often accompany Gardner's syndrome. It consists in a benign proliferation of fibroblasts with infiltration of muscles and fat tissue. It is diagnosed by ultrasound and CT-scans. The treatment of choice is the total surgical extirpation of the tumor. We report about a 19 year old patient with an isolated mesenteric fibromatosis following a normal pregnancy without previous surgical interventions.
