From: Complications of renal interventions: a pictorial review of CT findings
Post-contrast arterial phase axial CT images of a patient following two 14-gauge non-targeted core biopsies of the left kidney, demonstrating (a) left perinephric haematoma (white arrow). There is also a haematoma of the left psoas muscle, which is expanded (yellow arrow). b Active extravasation of contrast from a left inferior segmental renal artery (red arrow) was demonstrated inferiorly within the perinephric haematoma (white arrow). The active haemorrhage was successfully treated with embolisation coils of the left inferior segmental renal artery. The core biopsies confirmed IgA nephropathy
