Case Discussion

Pyelonephritis is most oftenly caused by bacterial invasion of the renal parenchyme. Clinical and laboratory findings are usually diagnostic. CT is used to evaluate for abscess formation. Striated nephrogram appears as areas of linear or wedge shaped hypoperfusion.

Other causes of a striated nephrogram include renal vein thrombosis and urinary obstruction.
