Complicated Acute Pyelonephritis With Extrarenal Manifestations Diagnosis With Sonography

The sonographic features of extrarenal manifestations of complicated acute pyelonephritis (APN) have rarely been reported. A case of severe APN in a young woman is presented with the imaging workup done exclusively by conventional sonography using color and power Doppler. Discussion places a focus on the imaging spectrum and clinical significance of the extrarenal manifestations. The hepatobiliary findings of APN appear to signify accompanying sepsis and gravity of the condition, and gallbladder wall thickening must not be misdiagnosed as acute cholecystitis.
