Meckel's Diverticulum Enterolith: A Rare Cause of Perforation and Small Bowel Obstruction Presenting as Acute Abdomen.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. MD enteroliths are an uncommon entity that could rarely present with complications. We, herein, present a case of a 56-year-old man who presented with severe abdominal pain. Preoperative CT showed an inflamed structure with central calcification connected to distal ileum lumen with an air pouch associated with small bowel obstruction. Upon laparotomy, a perforated MD was found with phlegmon formation. He underwent resection of the loops containing MD with end-to-end anastomosis.  This highlights the importance of radiological imaging in preoperative diagnosis of these conditions which should be kept in mind if we find a calcified lesion in an inflamed diverticulum around the midline region.
