BACKGROUND Cyclic vomiting syndrome (CVS) is a chronic functional gastrointestinal disorder involving the gut–brain interaction that is characterized by recurring episodes of nausea, vomiting, abdominal pain, and interspersed complete normal periods. Superior mesenteric artery (SMA) syndrome (SMAS) is a vascular condition in which the horizontal portion of the duodenum is compressed due to a reduced angle between the aorta and the SMA. This condition presents with symptoms similar to CVS, posing challenges in distinguishing between the two and often resulting in misdiagnosis or inappropriate treatment. CASE SUMMARY A 20-year-old female patient presented with recurrent episodes of vomiting and experienced a persistent fear of vomiting for the past 2 years. She adopted conscious dietary restrictions, which led to severe malnutrition. Initially, she was diagnosed with SMAS, as revealed by computed tomography angiography. Despite efforts to increase the angle between the aorta and the SMA through weight gain, her vomiting did not improve. Finally, she was diagnosed with comorbidities including CVS, SMAS and anxiety disorder. She underwent comprehensive interventions, including enteral and parenteral nutritional supplementation, administration of antiemetic and anti-anxiety agents, and participation in mindfulness-based cognitive therapy. The patient eventually experienced a notable improvement in both body weight and clinical symptoms. CONCLUSION We present a rare case of CVS in an adult complicated with SMAS and propose additional treatment with nutritional support, pharmacological intervention, and psychotherapy.
