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

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 [1,2].With non-specific radiological findings, a perinephric abscess can pose a diagnostic dilemma.[2, 3] Teaching points: 1) Radiological characterization and pattern of spread of perinephric abscess.[1]2) Imaging differentiation of perinephric abscess and cystic renal tumor.[3]
