Acute intestinal obstruction in a women, aged 56, was caused by a highly malignant adenocarcinoma arising in a Meckel's diverticulum. Despite radical surgery, the tumour recurred after four months, and the patient died nine months after her first operation. This confirms the general bad prognosis associated with carcimomas of Meckel's diverticulum.
