Fig. 2

a CT scan showing multiple cysts in the right kidney with peripheral hypoattenuation (orange arrow) characteristic of a hydatid cyst. b CT scan showing the typical “cyst within a cyst” appearance (orange arrow). c Anti—scolicidal agent (10% povidone–iodine) soaked mops (white arrow) isolating the hydatid kidney to prevent the spillage. d Numerous daughter cysts isolated from the excised kidney. e Pus mixed caseous material collected during aspiration (~ 2 Litres). f Scanner view showing the thick fibrotic pericyst (thick black arrow) compressing the native renal parenchyma at the periphery (thin black arrow). The intra-cystic material lies outside and shows the eosinophilic membrane (thin white arrow) corresponding to the ectocyst (hematoxylin and eosin, 20x). g Higher magnification of the thick fibrotic pericyst (black star) and the compressed native renal parenchyma. A compressed glomerulus is highlighted in the renal parenchyma (black arrow) (hematoxylin and eosin, 40x)
