Transverse colonic volvulus in a 16-year-old female with congenital myotonic dystrophy: A case report

•GI manifestations of MD are common.•Chronic constipation in an MD patient may indicate pseudoobstruction.•MD patients warrant a higher level of suspicion for surgical abdominal entities.

Transverse colonic accounts for 2–4% of all forms of colonic volvulus and has its highest mortality rate (33) [1], [2] and [3]. Only forty cases of pediatric transverse colonic volvulus have been reported in the literature to date [4]. We report on a 16-year-old female with congenital myotonic dystrophy who underwent operative repair for transverse colonic volvulus, the first reported case of these two entities in combination.
