A 76-year-old previously asymptomatic man presented to the emergency room with a 4-hour history of severe epigastric pain. This was accompanied by vomiting of food contents followed by repeated dry heaves. Examination was remarkable for tenderness in the epigastrium with no abdominal rigidity and normal bowel sounds. A nasogastric tube could not be inserted despite repeated attempts. The medical history was significant for a motor vehicle accident 2 years prior to admission that resulted in fracture of the left humerus, three left-sided rib fractures, and a splenic laceration that did not require surgery. An upright X-ray of the abdomen (figure 1) followed by computed tomography (CT) scan (figure 2) of the abdomen were performed.

What is the unusual finding in figure 1?
What are the CT scan findings in figure 2?
What test would confirm the diagnosis?



There is a single air fluid level in the midline but the gastric bubble normally seen in the left hypochondrium is absent.


The CT scan shows an abnormal axis of the stomach with the antrum (open arrow) anterior and lateral to the gastro-oesophageal junction (closed arrow) and at the same level as the gastric fundus. These findings are suggestive of a gastric volvulus.


A barium study would confirm the diagnosis. This study showed the greater curvature of the stomach (open arrow) located superior to the lesser curvature with the cardia and pylorus at the same transverse level confirming the presence of an organo-axial gastric volvulus (figure 3).


A gastric volvulus can be classified based on the axis of rotation (organo-axial, mesentero-axial or combined), severity (acute or chronic), extent (total or partial), direction (anterior or posterior) or aetiology (secondary or idiopathic).1

The characteristic triad of an acute gastric volvulus (box) was described in 1904 and validated in subsequent studies.2Chronic gastric volvulus usually manifests with vague abdominal symptoms such as dyspepsia, heart burn, eructation, nausea and vomiting long before the diagnosis is made.3

Characteristic triad of an acute gastric volvulus

  • sudden onset of constant and severe upper abdominal pain

  • recurrent retching with production of little vomitus

  • inability to pass a nasogastric tube

Our patient had an acute organo-axial gastric volvulus which was diagnosed by an abdominal CT scan and confirmed by a barium study. An unusual discovery was the absence of an associated hiatal hernia which is usually present in patients with an organo-axial gastric volvulus. An extensive search of the literature located only two reports of a CT-scan mediated diagnosis of gastric volvulus and both reports were of patients with a hiatal hernia or an intra-thoracic stomach.4 5

The finding of a single midline air fluid level in the upright abdominal radiograph was initially thought to be due to an associated hiatal hernia. However, although a very high dome of the diaphragm was noted during surgery in our patient, no defects or hernias were detected. Acute gastric volvulus is a rare condition but one which needs to be diagnosed quickly to avoid life-threatening complications like ischaemic necrosis, haemorrhage and gangrene. While a CT scan is not necessary to diagnose gastric volvulus, we suggest that a CT scan finding of the stomach in an unusually high position or an abnormal axis of the stomach with the antrum and gastro-oesophageal junction at the same transverse level in a patient with acute abdominal pain and vomiting should elicit the suspicion of a gastric volvulus.

Final diagnosis

Acute organo-axial stomach volvulus.
