Background: Gastric volvulus is a rare surgical emergency that causes an upper digestive obstruction due to a rotation of the stomach greater than 180°. Observation: We report the case of a 2-year-old patient referred from a health care facility for incoercible vomiting. On admission, the clinical examination revealed that the condition started about 1 month back with poor general and nutritional condition. Pyloric stenosis was suspected but this hypothesis was rejected based on abdominal ultrasound. Further investigations were done with an abdominal X-ray and an upper gastrointestinal barium study which led to the conclusion of an organo-axial gastric volvulus. The patient died in the course of treatment. Conclusion: Gastric volvulus is an often-misunderstood condition. Upper gastrointestinal barium study remains the gold standard of diagnosis. Its management is surgical.
