Segmental absence of intestinal muscle with ileal web in an extremely low birth weight infant: case report.

Spontaneous intestinal perforations are localized perforations without the typical clinical, radiological, and histopathological features of necrotizing enterocolitis. Spontaneous intestinal perforation is a recently defined clinical entity. The best-known risk factor is prematurity. It is seen 2-3% in very low birthweight infants and 5 % of extremely low birthweight infants. Herein we report an extremely low birthweight infant with spontaneous intestinal perforation, segmental absence of intestinal muscle and an ileal web as an underlying cause. We aimed to draw attention to the segmental absence of intestinal muscle which is rare but increasingly reported cause of spontaneous intestinal perforation and the importance of histopathologic examination of surgical specimens.
