A CASE OF CALCULUS IN A MECKEL'S DIVERTICULUM

Abstract

We present the case of calculus in a Meckel's deverticulum. A 67-year-old woman with a history of repeated attacks of lower back pain and vomiting several times a year was seen at the hospital because of lower back pain and vomiting. The patient was diagnosed with having intestinal obstruction by abdominal X-ray examination, and was admitted on the same day. After admission symptoms ameliorated following conservative treatment. Radiological enteroclysis and CT performed after symptomatic remission showed an abnormal shadow accompanied by polygonal calcification 2.5cm in diameter in the bowel, which was likely to be the ileum. Abdominal section performed to diagnose the intestinal abnormality revealed a projected diverticulum in a sac at a site 40cm towards the mouth from the terminal ileum. A foreign body was palpable within the lumen. There were no other abnormal findings such as stenosis or tumor of the small intestine. A section of the ileum about 5cm in range including the diverticulum was excised. The foreign body within the diverticulum was polygonal blackish brown stone with the size of 2.5×2.0cm and the thickness of 0.5cm, considered to be an intestinal stone. Histologically, the membrane of the diverticulum was ileal mucosa membrane. No findings of ectopic gastric mucosa nor malignancy was seen. Meckel's diverticulum containing an intestinal stone was diagnosed. We rarely encounter reports of Meckel's divertidulum containing an intestinal stone. This paper reports such a rare case together with some bibliographical comments.
