Pathogenesis

• unknown but could have to do with congenital abnormality with mucosal flap

Clinical signs

• soft, non painful swelling in throat latch region
• if swelling is large enough, can cause respiratory stertor, respiratory difficulty, occasional dysphagia and aspiration pneumonia

Pathogenesis

• secondary to upper resp infection with strep equi or strep zooepi
• rupture of retropharyngeal lymph node into the pouch

Diagnosis

• history of upper resp, physical exam and clinical signs
• confirmation via endoscopy or radiography (fluid line in GP)

Treatment

• medical treatment = lavage of the GP and administration of local and systemic antibiotics (may need to be repeated for several days until most of the exudate is removed)
• if medical therapy fails, may need to do surgical lavage and drainage if chondroids are present

Pathogenesis

• unknown but aspergillus is the common pathogen
• causes plaques typically on the dorsal aspect of the guttural pouch
• plaques can erode arteries and nerves

Clinical signs

• depends on structures involved (hemorrhage if artery is affected)
• dysphagia
• Horner's syndrome or facial nerve paralysis

Treatment

• surgical occlusion of affected arteries
• give antifungal meds (but not as effective as surgical intervention)
