Renal hydatid cysts are a rare manifestation of cystic echinococcosis in children and may present with nonspecific symptoms such as fever or flank pain. We report a 7-year-old child with prolonged contact with dogs who underwent abdominal imaging for febrile symptoms. Ultrasound revealed a well-defined cystic lesion in the upper and mid-pole of the right kidney with a thickened echogenic wall, internal septations, mobile echoes, and debris, suggestive of a complicated hydatid cyst. Contrast-enhanced CT confirmed a large cortical and parapelvic cyst with a hyperdense non-enhancing wall, fluid-density content, perirenal fat stranding, and an adjacent encysted fluid collection along the ipsilateral psoas muscle. This case highlights the complementary roles of ultrasound and CT in diagnosing renal hydatid disease, particularly superinfected cysts in pediatric patients from endemic regions.
