Tuberculous esophagitis with erosion into aortic aneurysm.

Area of Science:

• Medicine
• Pathology
• Infectious Diseases

Background:

• Atherosclerotic thoracic aneurysms pose significant risks, including rupture and hemorrhage.
• Tuberculous esophagitis is an uncommon esophageal infection, often presenting with vague symptoms.
• Esophageal fistulas to adjacent vascular structures are exceedingly rare but carry a high mortality rate.

Observation:

• An 87-year-old female with a known atherosclerotic thoracic aneurysm experienced sudden death due to massive esophageal hemorrhage.
• Prior to death, a biopsy confirmed tuberculous esophagitis.
• Autopsy revealed a fistulous tract connecting the esophagus to the aortic aneurysm, identified as the source of the fatal bleeding.

Findings:

• Histopathological examination of the fistulous tract showed a granulomatous inflammatory reaction.
• Acid-fast bacilli, indicative of tuberculosis, were identified within the inflammatory infiltrate.
• This represents the first documented case of tuberculous esophagitis directly involving an aortic aneurysm, leading to fatal hemorrhage.

Implications:

• This case highlights the potential for tuberculous esophagitis to cause devastating complications, including vascular erosion.
• It underscores the importance of considering tuberculosis in the differential diagnosis of esophageal pathology, especially in at-risk populations.
• The findings emphasize the critical need for prompt diagnosis and treatment of both aortic aneurysms and esophageal infections to prevent catastrophic outcomes.
