Echinococcosis of the detrusor: report of the first pediatric case

Abstract

Background: The parasitic disease known as the cystic echinococcosis (CE) is brought on by cysts made up of the larval forms (metacestodes) of Echinococcus tapeworms. In North Africa, it is greater in rural regions. This is unusual for a primary supravesical position. Case presentation: We report a case of a 6-year-old boy who had a palpable abdominal mass with hypogastric abdominal pain. A pelvic ultrasound examination demonstrated a voluminous intra-abdominal supravesical cystic formation with clear limits and regular contours of heterogeneous anechogenic echostructure and the presence of multiple hyperechoic septa separating the cubicles (daughter vesicles) in a honeycomb pattern. Computed tomography confirmed a cystic echinococcosis stage III of the pelvis. After a laparotomy surgery with total cystectomy, the patient was discharged with prescribed albendazole 10 mg/kg/day. Cystic echinococcosis was established by histological analysis. The aim is to demonstrate that from a literature search, we think this is the first case of cystic echinococcosis of the detrusor in children. Conclusion: Primary pelvic cystic echinococcosis is uncommon and even less common among children. Cystic echinococcosis must be taken into account in the differential diagnosis when there is an abdominal mass, particularly in locations where it is prevalent.
