Congenital fibrosarcoma of the bowel: Sonographic description of a rare case of neonatal intestinal obstruction

摘要

A case of localization in the bowel of congenital fibrosarcoma (a rare soft-tissue tumor usually occurring in the extremities) causing intestinal obstruction in a newborn girl is described. A focal thickening of the ileal wall with features mimicking intussusception was identified at sonography; the final diagnosis was achieved by means of molecular analysis after surgical removal of the mass.
