Plain-English summary

An 18-month-old male Bloodhound was brought to the vet because he had been having trouble breathing, making strange noises when he tried to bark, and was less active for the past six weeks. A CT scan showed a lump near his larynx (the voice box) that was pressing on it, causing his breathing issues. A procedure to look inside his throat confirmed he had laryngeal paralysis, and a biopsy of the lump suggested it was a benign muscle growth. The dog underwent surgery to fix the paralysis and remove the lump, and after the surgery, all his symptoms went away. At a follow-up appointment 13 months later, he was still doing well and showed no signs of any problems.

Abstract

An 18-month-old male entire Bloodhound dog was presented with a six-week history of progressive inspiratory dyspnoea, stridor, dysphonia and exercise intolerance. CT scan performed elsewhere had revealed the presence of an unencapsulated nodular mass (3x1x5 cm) dorsal to the larynx and first tracheal rings. Laryngoscopy demonstrated the presence of bilateral laryngeal paralysis and distorted laryngeal architecture suggestive of extraluminal compression. Histopathology results of incisional biopsies from the mass were suggestive of a benign non-neoplastic muscular lesion. Surgery was performed to manage laryngeal paralysis and attempt mass excision. A second histopathology examination confirmed an inflammatory and dysplastic lesion suggestive of a pseudotumour. All clinical signs resolved after surgery and at the 13 months follow-up the dog remains asymptomatic. To the authors’ knowledge, this is the first report of a case of laryngeal paralysis caused by a muscle pseudotumour in a young dog.
