Isolated Intestinal Neuronal Dysplasia- Type B of Ileum: a Rare Occurrence
Abstract Background: Intestinal neuronal dysplasia type B in the gastrointestinal tract is a rare occurrence and may occur alone or in combination with Hirschsprung disease. Distal colon seems to be frequent site for isolated IND-B cases, however small bowel involvement is scarcely reported. Case presentation: We report a case of 9 years old boy presenting with features of intestinal pseudo-obstruction for 5 years. Exploratory laparotomy revealed narrowed distal ileum with huge proximal dilatation. Histopathology of the resected terminal ileum revealed giant submucosal ganglion, hyperplastic submucosal nerves and ectopic ganglion cells in the lamina propria suggestive of IND-B.Conclusions: Although IND-B involving ileum is a rare occurrence, suspicion should be kept in cases of intestinal obstruction with minimal response to conventional treatment.
