“…In ultrasound examination, the whirlpool sign, as a widely documented finding, can be observed in various intestinal torsions, including small bowel torsion, cecal torsion, sigmoid colon torsion, closed-loop intestinal obstruction, and others [ 18 , 19 ]. Its significance as a diagnostic indicator is particularly prominent, especially in pediatric patients presenting with acute abdominal pain, where early diagnosis and intervention are crucial.…”

Background Acute complete gastric volvulus is a rare and life-threatening disease, which is prone to gastric wall ischemia, perforation, and necrosis. If it is not treated by surgery in time, the mortality rate can range from 30 to 50%. Clinical presentations of acute gastric volvulus are atypical and often mimic other abdominal conditions such as gastritis, gastroesophageal reflux, gastric dilation, and pancreatitis. Imaging studies are crucial for diagnosis, with barium meal fluoroscopy being the primary modality for diagnosing gastric volvulus. Cases of acute gastric volvulus diagnosed by ultrasound are rarely reported. Case presentation We reported a rare case of acute gastric volvulus in a 4-year-old Chinese girl who presented with vomiting and abdominal pain. Ultrasound examination revealed the “whirlpool sign” in the cardia region, raising suspicion of gastric volvulus. Diagnosis was confirmed by X-ray barium meal fluoroscopy, which indicated left-sided diaphragmatic hernia and obstruction at the cardia region. Surgical intervention confirmed our suspicion of acute complete gastric volvulus combined with diaphragmatic hernia. Conclusion In this case, we reported an instance of acute complete gastric volvulus. Ultrasound revealed a “whirlpool sign” in the cardia, which is likely to be a key sign for the diagnosis of complete gastric volvulus.
