Core Tip

Core tip: Renal hydatid is generally secondary to disseminated hydatidoses or associated with hepatic involvement. Isolated renal involvement is far less common and reported in less than 5% of all hydatid cases. Without appropriate history a subset of renal hydatid, especially type 4 cyst may simulate cystic renal/urothelial neoplasm or other complex cystic lesions such as abscess. Radiologists must harbour a high index of suspicion and look for subtle imaging signs such as calcification and non enhancing “solid” component to include this diagnosis in the differential of complex renal lesion. Absence of relevant history or hepatic involvement should not prevent diagnosticians from entertaining this rare diagnosis.
