Background and Clinical Significance: Cystic Echinococcosis (CE), also known as hydatid disease is a zoonosis in whose life cycle human can be an accidental intermediate host. The liver is the most commonly affected organ, with complications like cyst rupture, hematogenous spread and infection. Imaging techniques such as ultrasound, CT and MRI play a vital role in diagnosing and classifying the disease, facilitating the appropriate therapeutic approach. Treatment options include albendazole for early-stage cysts with more invasive procedures like PAIR, MoCAT and surgery for advanced cases. This article highlights the importance of imaging modalities in diagnosing and therapeutic management of CE. Case Presentation: We report the case of a 23-year-old female patient presented with nausea, fatigue and loss of appetite to the emergency department, who was diagnosed with a giant Echinococcosis lesion. Conclusions: This case highlights the importance of imaging modalities in diagnosing and therapeutic management of CE.
