@onthewardsco: How do you recognize acute pyelonephritis on CT? Here’s a quick radiology review of the major CT findings of pyelonephritis, including wedge-shaped or patchy hypoenhancement, striated nephrogram, delayed or diminished nephrogram, renal enlargement, perinephric fat stranding, thickening of Gerota’s fascia, and loss of corticomedullary differentiation. I also cover important complications of pyelonephritis on CT, including renal abscess, perinephric abscess, pyonephrosis, urinary obstruction, hydronephrosis, and emphysematous pyelonephritis, plus how to distinguish pyelonephritis from an important mimic: renal infarction. A helpful framework for medical students, residents, interns, and anyone learning abdominal CT interpretation, renal imaging, emergency radiology, internal medicine, or diagnostic radiology. Save this for the next time you see flank pain, fever, UTI symptoms, or suspected complicated pyelonephritis and need to know what to look for on CT. #MedTok #medicine #medstudent #nursetok #np
