Infectious aortitis with mycotic pseudoaneurysm

Discussion:

Laboratory values:

  • WBC 23.8 
  • Lactate 13.2
  • Blood cultures positive for MRSA 

Infectious aortitis with small pseudoaneurysm. The periaortic stranding, adenopathy, and history of fever with leukocytosis should lead to very high suspicion for this diagnosis. The pseudoaneurysm is likely mycotic in origin.

A detailed operative note is provided for review. Attempt at cadaveric repair was unsuccessful due to irreversible coagulopathy, eventually resulting in the patient's demise.
