Unexpected Cause of Abdominal Mass in an Adult: Isolated Enteric Duplication Cyst

Abstract

Enteric duplication cysts are uncommon congenital anomalies, encountered majorly in pediatric population, with an approximate prevalence of approximately 1 in 4500 births. They usually remain asymptomatic in adults. IDEC is rarest subtype of all EDCs furthermore foregut duplication cyst present in paracaeal region adds on to its rarity. We herein present a case of A female in her late 20s presented with complaints of pain in the right lower abdomen for the last one year, with a palpable lump on examination. She underwent exploratory laparotomy and the cyst was excised with all its walls intact with no bowel resection. On HPE it was suggestive of enteric (foregut) duplication cyst presented in paracaecal region. The post-op period and follow-up were uneventful. The treatment involves surgical management with en-bloc resection without the resection of the adjacent bowel owing to an isolated or independent blood supply of the cyst.
