Redundant: A case of complicated dolichocolon in a neonate

Abstract

Dolichocolon has been described as a developmental variant and is characterized by redundancy of the colon. Diagnosis is based off clinical symptoms and barium enema or CT-colonography. This redundancy is often seen in the adult and elderly population, with pediatric prevalence limited to case reports. Information regarding radiologic evaluation is limited, as most cases are documented outside of the radiology literature. This case report demonstrates a complex course of transient symptoms of constipation, obstruction, and suspected volvulus in a 1-month-old with dolichocolon. A retrospective review of the images offers insight into gaining suspicion of this variant in radiographs and fluoroscopic exams. Keywords: Pediatric dolichocolon, Fluoroscopy, Barium enema
