Tracheal intussusception, a rare condition where a tracheal segment invaginates, can mimic an annular mass on imaging. This case highlights the importance of considering tracheal intussusception in diagnosing tracheal abnormalities.
Area of Science:
- Veterinary Medicine
- Comparative Pathology
- Diagnostic Imaging
Background:
- Chronic cough in dogs can stem from various tracheal abnormalities.
- Differentiating intraluminal masses from other tracheal lesions requires advanced imaging.
- Tracheal intussusception is an uncommon condition not frequently considered in differential diagnoses.
Purpose of the Study:
- To describe a case of tracheal intussusception in a dog.
- To illustrate the diagnostic process using radiography, endoscopy, and computed tomography (CT).
- To emphasize tracheal intussusception as a differential diagnosis for annular tracheal masses.
Main Methods:
- Radiographic examination of the trachea.
- Endoscopic evaluation of the tracheal lumen.
- Thoracic computed tomography (CT) for detailed anatomical assessment.
Main Results:
- Radiography revealed an opacification suggestive of a foreign body in the trachea.
- Endoscopy identified a circumferential, flap-like lesion within the trachea.
- CT confirmed cranial displacement and invagination of a tracheal segment, consistent with tracheal intussusception.
Conclusions:
- Tracheal intussusception can present as an annular mass on diagnostic imaging.
- A combination of radiography, endoscopy, and CT is valuable for diagnosing tracheal intussusception.
- Veterinary clinicians should consider tracheal intussusception in the differential diagnosis for dogs with chronic cough and apparent tracheal masses.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
