An abnormally large prostatic utricle cyst associated with unilateral renal agenesis
An 8-year-old male child was admitted for painful micturition along with high-grade fever with gradually progressive increasing abdominal girth since 3 weeks. There was no history of hematuria, jaundice or tuberculosis. On examination, a diffuse, tender, tense swelling was seen over the lower abdomen. Per rectal examination showed a cystic pelvic mass. He was further investigated with a probable diagnosis of cystic teratoma and duplication cyst. On contrast-enhanced computed tomography (CT), a large cystic lesion was seen posterior to the bladder at the prostatic utricle []. CT abdomen revealed a large, well-defined, thick-walled, fluid density lesion measuring 14 cm × 11 cm × 9 cm arising from the pelvis in the posterior vesical, prerectal space extending superiorly above the umbilicus []; the urinary bladder and bowel loops are displaced. Left kidney and ureter were not visualised []. Right ureter was stretched over the lesion and compressed in its lower 1/3rd. Mild hydronephrosis and hydroureter was noted. He underwent laparotomy with excision of the infected cyst. We received an already cut-opened, large, thick-walled cyst measuring 12 cm × 10 cm × 9 cm. The inner surface was trabeculated. Histopathological examination showed a fibromuscular, fibrocollagenous cyst wall lined extensively by exuberant granulation tissue [] partly lined by flattened cuboidal epithelium []. In view of the clinical findings, a diagnosis of prostatic utricle cyst was rendered.
