Two Cases of Primary Reshaped Hydatid Cysts Mimicking Digestive Solid Cystic Masses

Abstract

Hydatidosis is a zoonotic parasitic infection that usually affects the lungs and liver but can occur in any organ. Peritoneal hydatidosis occurs in 5-16% of patients and can present with diverse clinical symptoms, often leading to misleading paraclinical exam results. Surgical intervention remains the primary treatment option, and prevention measures are implemented to protect susceptible populations. We present two cases of primary reshaped hydatid cysts mimicking digestive solid cystic masses, which were resected and found to be remodeled hydatid cysts on anatomopathological examination. The primary form of peritoneal hydatidosis is rare and can be confused with other cystic or pseudo-cystic masses of the peritoneum. Hydratic serology, while useful, is losing interest due to its delay in diagnosis, and surgery is the preferred therapeutic option. Recurrence is possible, making it necessary to implement preventive actions to interrupt the parasite's life cycle. Distant follow-up is necessary to monitor the patient's condition for up to 5 years.
