Meckel’s diverticulum is a rare gastrointestinal congenital anomaly that is difficult to diagnose and presents with anemia, abdominal pain, or intussusception was described originally by Guilhelmus Fabricius Hildanus in 1598. [1,2] A Meckel’s diverticulum is usually an asymptomatic condition, and many cases are incidentally discovered during a radiographic evaluation or during surgery performed for other reasons.  The diagnosis is usually made in childhood. Here, we report the case of a 44-year-old female with a volvulated Meckel’s diverticulum, causing a small bowel obstruction. The patient initiated with profuse diarrhea and vomiting bilious content; then started with abdominal distention and severe abdominal pain, becoming an intestinal obstruction. Later, the patient was surgically intervened; finding a Meckel’s diverticulum volvulated in the intraoperative that was causing the obstruction.
Meckel's diverticulum is rarely diagnosed in adults. It is usually asymptomatic and becomes evident when complicated.  Of the few reported cases; intestinal obstruction is the most common presentation in adult and is the second most common in children.
