Successful percutaneous drainage of a refractory caudal mediastinal paraesophageal abscess in a dog.

Abstract

OBJECTIVE: To describe a novel technique for paraesophageal abscess drainage in a dog. CASE SUMMARY: A 6-year-old dog presented for pyrexia of unknown origin, subsequently confirmed to be due to a paraesophageal abscess. This was managed by the ultrasound-guided placement of a thoracostomy tube into the abscess, allowing drainage to be performed. This led to clinical resolution and, at an 8-month follow-up, the dog continued to do well. NEW OR UNIQUE INFORMATION PROVIDED: Paraesophageal abscessation is typically managed with surgical intervention, which carries inherent risks and complications. This report describes a novel technique that did not require general anesthesia or invasive surgical intervention, achieving clinical remission without any adverse effects. It also summarizes the current literature available on this condition.
