Plain-English summary

A 10-year-old domestic shorthair cat was brought in for a noticeable swelling in the neck. The vet found that the cat had a cystic thyroid mass, which can sometimes cause breathing issues if it presses on the trachea. After performing an ultrasound and some tests, the vet successfully removed the mass through surgery. The cat recovered well, and follow-up showed a great long-term outlook for its health.

Abstract

Reports of cystic thyroid and parathyroid masses in cats are uncommon. Herein, the authors describe a series of four cats with cystic ventral cervical lesions, among them thyroid cyst (n=1), thyroid cystadenoma (n=2), and parathyroid adenocarcinoma (n=1). Presentations ranged from completely asymptomatic cervical swellings to signs related to local compression of adjacent structures (e.g., trachea). Ultrasonographic evaluation was helpful in localization of the mass in two cases. Hormone analysis and concentration of cystic fluid were performed in one cat. Surgical excision was performed successfully in three cases. Histopathological examination was performed in all four cases. Long-term prognosis was excellent for those cases in which follow-up was available.
