Myenteric ganglionitis is a disorder that causes intestinal motor dysfunction. It may be caused due to neoplastic, central nervous system, or systemic infectious disorders. However, some cases are considered to be idiopathic in origin. A 33-year-old man was admitted to the hospital with sudden severe abdominal pain accompanied by watery diarrhea. Computed tomography imaging revealed edema of the entire small intestinal wall without ischemic changes. Detailed examination could not be performed for identifying the cause of abdominal pain because of the patient’s worsened general condition, and he died 7 days after onset. The autopsy results confirmed the cause of the patient’s severe abdominal pain as an idiopathic myenteric ganglionitis. Some patients with idiopathic myenteric ganglionitis might die without a definitive diagnosis during their lifetime because of the rarity of this disease. When encountering severe intestinal motility abnormalities of unknown cause, physicians should consider idiopathic myenteric ganglionitis when choosing therapy.
