The horses presented with bimodal age distribution, with 5 cases in mature horses (age 8\u201321 years) and 3 in foals (age 1, 6 and 10 months). Mature cases presented for dysphagia or intermittent oesophageal obstruction (2\/5), and retropharyngeal swelling (3\/5), whereas respiratory stridor and visible mass were presenting complaints in the foals. Presence of a right\u2010sided (5\/8) or dorsally located (2\/8) palpable retropharyngeal mass of 3\u201335 cm diameter was noted clinically; one left\u2010sided mass was identified as an incidental finding at necropsy. Ultrasonography typically revealed a thick\u2010walled cyst containing hypoechoic fluid with dependent hyperechoic masses consistent with blood clots. Radiographs and upper airway endoscopy were also consistent with a retropharyngeal mass. Fluid cytology revealed chronic haemorrhage in 6\/8 cases, and squamous epithelial cells in one case. Histopathology in all cases demonstrated an epithelium\u2010lined cyst with no smooth muscle or thyroid tissue. Two cases was subjected to euthanasia; one due to concurrent laryngeal anomalies and one due to financial constraints. The remaining 5 cases were treated via surgical excision. Post operatively, right laryngeal hemiplegia was observed in 4\/5 cases. All previous reports of BRC in the horse have described juvenile individuals. Brachial remnant cyst should be considered a differential diagnosis for mature horses with masses of the throatlatch area and can be definitively diagnosed by the presence of squamous epithelium in aspirated fluid or by histopathology of the excised mass. Right recurrent laryngeal nerve damage is a common complication of surgery.<\/jats:p>","DOI":"10.2746\/042516409x452161","type":"journal-article","created":{"date-parts":[[2009,12,1]],"date-time":"2009-12-01T02:18:17Z","timestamp":1259633897000},"page":"918-923","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Branchial remnant cysts of mature and juvenile horses"],"prefix":"10.1111","volume":"41","author":[{"given":"R.
