A Tale of a Life-Threatening Twist: A Rare Case of Transverse Colonic Volvulus in an Infant.

Transverse colon volvulus (TCV) secondary to intestinal malrotation is exceptionally rare in pediatric patients, frequently causing delay in diagnosis and severe complications. Prompt recognition guided by diagnostic imaging is critical for improving outcomes in affected children. A previously healthy nine-month-old male presented acutely with significant abdominal distension, metabolic acidosis, and septic shock. Initial plain radiography indicated colonic obstruction, and subsequent ultrasound was equivocal in elucidating the cause of obstruction. Eventually, a contrast-enhanced barium enema confirmed the cause of obstruction as colonic volvulus, demonstrating a characteristic "beaked" appearance within the transverse colon. Subsequent emergent laparotomy revealed extensive bowel necrosis due to volvulus-induced ischemia caused by intestinal malrotation. Timely surgical management included ileocolectomy, temporary open abdomen management, and successful staged reconstruction, resulting in complete patient recovery. This case highlights the importance of considering uncommon, acutely life-threatening etiologies of disease processes in the pediatric population such as colonic volvulus. It also signifies the indispensable role of dynamic contrast-enhanced imaging studies that not only facilitate the diagnosis of colonic volvulus in the pediatric population but also allow for timely surgical management, and thus significantly reduce morbidity and mortality.
