Polyarteritis nodosa (PAN) is an inflammatory vasculitis that creates regions of stenosis and aneurysm formation. The authors describe a 66-year-old female with hepatic artery rupture as the first presentation of undiagnosed PAN, presenting with abdominal pain followed by hemorrhagic shock. This aneurysm was suture ligated with a successful outcome. A mesenteric arteriogram demonstrated lesions consistent with PAN including aneurysms of the left gastric branches, right and left hepatic arteries, and beaded appearance of the iliac artery. However, she developed massive pulmonary embolism from which she did not recover after discharge. Postmortem examination confirmed left hepatic artery aneurysm rupture and changes consistent with PAN on gross anatomical examination and histology. This report provides a unique overview of the disease process through imaging, gross anatomic specimen and pathology. Life-threatening hepatic artery aneurysm rupture is an uncommon presentation of PAN which may benefit readers in creating a more robust differential diagnosis.
