What does this research mean for the field?

An organized hematoma with an arteriovenous fistula can mimic a splenic artery pseudoaneurysm in necrotizing pancreatitis, but can be differentiated by atypical imaging features such as predominant portal venous phase filling and the absence of clear arterial communication. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To describe a rare diagnostic pitfall in which an organized hematoma accompanied by an arteriovenous fistula mimicked a splenic artery pseudoaneurysm in severe necrotizing pancreatitis.

Implication

Case report demonstrates an organized hematoma with arteriovenous fistula mimicking splenic pseudoaneurysm, highlighting diagnostic pitfalls in necrotizing pancreatitis.

Key Points

To describe a rare diagnostic pitfall in which an organized hematoma accompanied by an arteriovenous fistula mimicked a splenic artery pseudoaneurysm in severe necrotizing pancreatitis.
Assessed a patient with severe necrotizing pancreatitis using serial multiphasic contrast-enhanced computed tomography (CT) and selective angiography.
Administered prophylactic proximal splenic artery coil embolization followed by splenectomy after post-procedure imaging showed persistent abnormal arterial flow.
Serial CT demonstrated a hyperdense splenic hilar lesion growing from 22 mm to 54 mm over a short interval with arterial and delayed venous phase enhancement.
Histopathologic examination following splenectomy confirmed an organized hematoma with an arteriovenous fistula rather than a true pseudoaneurysm.
Retrospective image analysis revealed atypical features, including predominant portal venous phase filling and absent discrete arterial communication on angiography.
