A subcapsular perirenal haematoma is a form of perirenal haematoma where blood accumulates beneath the renal capsular margin.
It can arise from a number of causes
CT
Typically seen as crescentic haematoma peripherally encapsulating a portion of the kidney. The attenuation value depends on the age of the haemorrhage.
History and etymology
A spontaneous renal haematoma is thought to be initially reported by Bonet et.al in 1679 3.

-
perirenal abscess: different clinical context unless rarely when superinfection of a perirenal haematoma leads to an abscess
