A Case of Perinephric Abscess - Radiological Characterization from Cystic Renal Tumour

Dr. Sharmada Vakwadi Holla, Dr. Pooja K, Dr. Ashwini M

Abstract: Perinephric space is a space on each side which is distinctly defined by the cone of renal fascia. A variety of pathologies can occur in this space which are categorised based on their clinical and radiological presentation. An abscess within the perinephric space is a potentially fatal disease which occurs secondary to a site of renal infection that perforates through the capsule to contaminate the perirenal fatty compartment. With non-specific radiological findings, a perinephric abscess can pose a diagnostic dilemma. Teaching points: 1) Radiological characterization and pattern of spread of perinephric abscess. 2) Imaging differentiation of perinephric abscess and cystic renal tumor.
