An unusual case of type a posterior cloaca associated with 46xx disorder of sexual differentiation with y duplication of urethra

Abstract

We report an infant reared as a girl who presented with ambiguous genitalia and urine coming per rectum. On examination, she had minimal clitoromegaly with labial fusion and Y urethral duplication. On investigations, genetic, metabolic, and endocrine causes for disorder of sexual differentiation were ruled out. This girl was operated via a posterior sagittal approach. This case was unique in that the urogenital sinus was deviated posteriorly and opened in the anterior rectal wall and the accessory urethra opened in clitoris, along with ambiguity of external genitalia, thus making it a rare variant of the posterior cloaca. The diagnosis requires a high index of suspicion in clinician and a meticulous examination of the external genitalia. Very little literature is available for this rare anomaly. Few reports have classified them as female pseudohermaphroditism with cloacal and urogenital sinus defects. Hence, we hereby discuss and review the literature for previously reported cases.
