Paraesophageal abscess
As a veterinarian, I am frequently confronted with complex chest diseases where a thorough diagnosis and prompt treatment determine the prognosis. A typical example is a paraesophageal abscess – a collection of pus in the tissue adjacent to the esophagus. A paraesophageal abscess usually develops as a result of a small perforation of the esophagus, often caused by swallowed foreign bodies (e.g., bones, sticks, fishhooks) or by secondary infections in the mediastinum. Even wood splinters that migrate easily from the throat or tongue can travel caudally along tissue fascia and cause a paraesophageal abscess near the esophagus. We see the interplay of a foreign body, local inflammation, bacterial colonization, and an encapsulated pus-filled cavity relatively frequently in dogs, whereas it is less common in cats.
