[CT of the pelvic kidney]

Six cases of unilateral pelvic kidney are presented. CT features are summarized as follows: (1) an absence of a kidney in the renal fossa with normal sized opposite kidney: (2) a pelvic kidney whose hilus faces in various directions; and (3) homogeneous parenchymal enhancement and visualization of the pyelocalyceal system on post-contrast CT. In the study of suspected pelvic kidney, CT is a useful diagnostic tool.
