Retrorectal Bronchogenic Cyst With a Sacrococcygeal Surgical Approach

Abstract

We present a case of a bronchogenic cyst in the retrorectal space that was successfully treated with a unique sacrococcygeal surgical approach, thus avoiding abdominal access. This report aims to enhance the literature with our technique and to help the scientific community in treating future retrorectal bronchogenic cyst cases. A 19-year-old man presented to the hospital with testicular pain refractory to overthe-counter analgesics. A cyst lesion in the presacral region was found during pelvic magnetic resonance imaging. We identified the cyst's epithelium as the respiratory type, containing ciliated pseudostratified columnar epithelium with foci of squamous metaplasia. The bronchogenic cyst is abnormal from the primitive foregut, and its location on the retrorectal site is rare. Patients with this type of lesion are usually asymptomatic, and discovery is commonly incidental during imaging exams. Excision is advised, and the prognosis is good after retroperitoneal bronchogenic cyst removal. Our description of the topic is essential to assist future similar cases.
