• Visceral artery pseudoaneurysms(VAPA) are a frequent cause of sudden onset intra-abdominal hemorrhage. • A spectrum of various etiologies like iatrogenic, pancreatitis, trauma, tumors, vasculitis etc. can lead to VAPAs. • MDCT Angiography is the modality of choice for the diagnosis of affected artery, assessing underlying etiology and planning further intervention. • Varying etiologies can often lead to varying imaging parameters in VAPAs.

Firstly, we briefly discuss the epidemiology of visceral artery pseudoaneurysms(VAPA). Then, we discuss MDCT abdominal angiography protocol and imaging reconstruction manipulations. Further, a case based review of VAPA secondary to various etiologies are discussed, including LGA PA secondary to pancreatitis RHA PA at the margin of a hepatic abscess Splenic artery PA due to large pancreatic mass Post Whipples’ surgery GDA stump blow-out PA Post laparoscopic cholecystectomy cystic artery blow-out PA RHA PA secondary to acute cholecystitis Renal artery PA post PCNL Middle colic artery PA post pancreatitis Renal artery PA due to angiomyolipoma Post trauma RHA PA Post trauma splenic stump blow out PA RHA PA due to hepatoblastoma Ruptured GDA PA post pancreatitis We close with few take home messages.
