I guess hydatid acn occur any where but i have not seen a renal hydatid.
Click on renal hydatid...
This is caused by Echinococcus which is a tape worm. Human beings become intermediate host during the life cycle of this parasite. Read more on echinococcus...
Imaging findings in hydatid disease depend on the stage of cyst growth (ie, whether the cyst is unilocular, contains daughter cysts, or is partially or completely calcified [dead]) . A difference in attenuation and signal intensity between the fluid in the central portion of the cyst and that in the peripheral cysts is a typical finding in echinococcosis due to a difference in content .Daughter vesicles (brood capsules) are small spheres that are formed from rests of the germinal layer and appear as cysts within a cyst. They contain the scolices and hooklets, along with sodium chloride, proteins, glucose, ions, lipids, and polysaccharides . When daughter cysts are separated by the hydatid matrix, they demonstrate a "wheel spoke" pattern . (Syndicated from Sumer's Radiology site)
