EC Clinical and Medical Case Reports

Background: Hydatid disease is a parasitic zoonosis caused by Echinococcus granulosus, endemic in developing countries. The liver and lungs are the most frequently affected organs, while splenic involvement is rare, representing less than 5% of all cases.

Case Presentation: We report a 7-year-old child presenting with both splenic and pulmonary hydatid cysts. Contrast-enhanced CT demonstrated a well-defined cystic lesion in the spleen with internal floating membranes and an additional cystic lesion in the left lower lung lobe.

Conclusion: This case underlines the role of cross-sectional imaging in detecting multiple hydatid localizations and guiding multidisciplinary management in pediatric patients.
