Primary peritoneal cystic echinococcosis: a rare surgical entity

2026Open accessMohammed V University

In plain language

Hydatidosis is a parasitic disease caused by Echinococcus granulosus larvae and presents a major public health concern in endemic areas, including Morocco. Secondary peritoneal hydatidosis occurs when larvae disseminate into the peritoneal cavity, creating a rare and varied clinical condition. A single case illustrates this presentation in an individual referred for recurrent hepatic hydatid cysts. While physical examination showed no obvious abnormalities, serological tests were strongly positive. Abdominal computed tomography proved vital by revealing both the recurrent hepatic cysts and multiple peritoneal cystic lesions. Treatment involved surgical excision and drainage of the cysts, followed by adjuvant medical therapy with albendazole. The individual recovered without complications. The findings emphasise that imaging is critical for diagnosing peritoneal hydatidosis and confirm that combining surgical intervention with antiparasitic medication provides an effective management approach for this challenging condition.

Key takeaways

  • Peritoneal hydatidosis is a rare, diagnostically challenging condition resulting from the intraperitoneal spread of Echinococcus granulosus larvae.
  • Abdominal computed tomography was essential for detecting multiple peritoneal lesions alongside recurrent hepatic cysts when physical examination was unremarkable.
  • A combined treatment strategy using surgical excision, drainage, and postoperative albendazole therapy led to an uneventful recovery.

Why it matters

Hydatidosis remains a significant public health issue in endemic regions. Because peritoneal hydatidosis can present without distinct physical symptoms, understanding how to accurately diagnose and treat it is vital. Documenting effective diagnostic workflows and combined surgical and medical treatments helps clinicians better identify and manage rare parasitic complications, ultimately improving patient recovery outcomes.

Commercialisation angle

The abstract does not indicate an application pathway, as it describes a standard clinical case managed with existing surgical techniques and established antiparasitic medication.

Abstract

Hydatidosis is a cosmopolitan parasitic disease that represents a major public health concern in endemic regions such as Morocco. Secondary peritoneal hydatidosis results from intraperitoneal dissemination of Echinococcus granulosus larvae. This rare condition is polymorphic in presentation, and its diagnosis relies on a combination of epidemiological, clinical, biological, and radiological findings. We report a rare case of peritoneal hydatidosis in a patient referred for management of recurrent hepatic hydatid cysts. Physical examination was unremarkable, while serological testing for hydatidosis was strongly positive. Abdominal computed tomography was essential in demonstrating hepatic recurrence associated with multiple peritoneal cystic lesions. The patient underwent surgical management consisting of cyst excision and drainage. Postoperative recovery was uneventful, and adjuvant albendazole therapy was initiated. Peritoneal hydatidosis remains a rare and diagnostically challenging entity. This case highlights the pivotal role of imaging in establishing the diagnosis and supports combined surgical and antiparasitic management as the cornerstone of treatment.
