Abstract: Objective To analyze the CT and clinical features of acute pancreatitis(AP) patients with perirenal space(PRS) invasion.Methods CT images and renal function tests(serum urea,creatine) changes of 64 AP patients were retrospectively studied. PRS invasion by inflammation on CT scan and the relation between PRS invasion and renal function changes were analyzed. Results 81% patients had PRS invasion in which 52% were grade B, 25% were grade C. CT features of the PRS invasion varied from mild inflammatory changes to fluid collection or phlegmonous.The PRS invasion was detected in 35 of 52 patients with mild pancreatitis and all severe pancreatitis. Renal function abnormity was 47%, only 3% patients had abnormal renal function in patients without PRS invasion compared to 44% patients with PRS invasion. PRS invasion in patients with abnormal renal function attenuated on CT scan after the pancreatitis was controlled. Conclusions The CT clearly reveals the features of PRS in acute pancreatitis patients. The attenuation of PRS invasion in acute pancreatitis patients on CT parallels renal function recover.
