Giant inflammatory fibroid polyp of ileum causing intussusception: a case report.

Inflammatory fibroid polyps are rare, localized, non-neoplastic lesions originating in the submucosa of the gastrointestinal tract. Intussusception due to inflammatory fibroid polyps is uncommon; moreover, ileo-ileal intussusception has only rarely been reported. Here, we report an 11 x 7 cm giant inflammatory fibroid polyp of the small bowel that presented as intussusception in a 73-year-old woman. Ultrasonography demonstrated a solid, homogeneous, echogenic mass surrounded by the typical mural layers of an invaginated ileum. The immunohistopathological diagnosis after segmental ileal resection was an ileal inflammatory fibroid polyp. Although encountered rarely in adults, physicians should be aware of invagination and consider it in each case of acute abdomen because of the wide spectrum of clinical settings.
