Abstract
Anorectal malformations (ARMs) encompass a complex spectrum of congenital anomalies
and H/N type anorectal malformations are extremely rare. In the presence of colostomy,
an augmented pressure colostogram with or without retrograde or micturating cystourethrogram
is the investigation of choice. Transperineal ultrasound is an imaging technique that
allows a fairly accurate morphological assessment of ARMs along with dynamic evaluation
of the anorectal structures and pelvic floor anatomy. Here we describe the role of
transperineal ultrasound as an adjunctive modality in diagnosis of one such complex
anomaly.
