A 16-year-old adolescent with a history of minor abdominal trauma diagnosed with a giant isolated primary splenic hydatid cyst: a case report.

Introduction: Hydatosis is a zoonotic parasitic disease caused by echinococcosis larval infection. South America, Africa, the Middle East, South Europe, India, and Australia are endemic to this disease. Splenic involvement is a rare and complicated hydatid disease presentation. A splenic hydatid cyst is an infrequent clinical occurrence, even in regions where the disease is endemic. Case presentation: A 16-year-old male, having a background of mild abdominal trauma and non-resolving dull abdominal pain attended a paediatric surgical outpatient office and following a thorough examination, was diagnosed with a giant solitary isolated splenic hydatid cyst. Subsequently, the patient received albendazole and underwent total splenectomy, necessitated by the considerable size of the cyst, classified as a giant. Clinical discussion: Splenic involvement of hydatid disease is a rare presentation (0.5-8%.). With the initial clinical finding often involving the accidental discovery of a palpable mass, the most frequently reported symptoms and signs include the presence of a palpable mass, fever, dull pain, or splenomegaly. Ultrasound and computed tomography are the most helpful tools for evaluating focal splenic diseases. The preferred treatment involves the use of antihelminthic drugs such as albendazole or mebendazole in conjunction with splenectomy. Total splenectomy is the preferred approach and is associated with decreased hospital stay, reduced healthcare costs, and a lower likelihood of recurrence. Conclusion: in endemic areas, in patients with splenic cysts, hydatidosis should be contemplated.
