Eosinophilic enteritis with enteroliths: A diagnostic dilemma

Eosinophilic gastroenteritis (EG) is a rare disease, characterized by eosinophilic infiltration of different layers of intestinal wall. Thus having a wide spectrum of presentation leading to diagnostic dilemma.

We report a case of 55 years old female who presented with pain in abdomen, constipation, vomiting off and on with passage of stools on alternate days since 6 months. Plain radiographs showed radio-opaque densities in abdomen. Contrast enhanced computed tomography (CECT) of abdomen showed Ileal stricture with dilated proximal bowel loops with enteroliths. Exploratory laparotomy confirmed ileal stricture with thickening of the mesentery and an ileal diverticulum. Resection of ileal stricture was performed. The resected segment contained seven hard, black enteroliths. Histopathology of the resected specimen confirmed EG. Stone analysis showed dense faecal matter with bile salts.

EG leads to symptoms ranging from vomiting, abdominal pain, diarrhoea, blood loss in stools, anaemia to malabsorption resulting in diagnostic dilemma. It may cause gastrointestinal obstructive symptoms secondary to stricture, depending upon the predominant layer involved.

The differential diagnosis of EG should always be considered when dealing with gastroenteritis presenting with radio-opaque densities in abdomen.
