Cabergoline Administration after Ovariohysterectomy in a Queen with Fibroepithelial Hyperplasia

Abstract

In this case report, the diagnosis and treatment process of fibroepithelial hyperplasia developing in the mammary glands of an 11-month-old Tabby female cat is presented. Medical history revealed that the cat had been in heat once before, her udders were gradually swollen in the last 15 days, her appetite and general condition were normal, and there was no previous progesterone application. On physical examination, all breast lobes were excessively tight bilaterally, swollen breasts were gel-like and painless on palpation, hyperemia and milk secretion around the nipples were noted. Laboratory tests showed that serum progesterone level was 3.02 ng/ml and estrogen level was 5.2 pg/ml. Fibroepithelial hyperplasia was diagnosed based on medical history, clinical examination and laboratory analysis. Ovariohysterectomy operation was performed as the treatment. One day after the operation, cabergoline was administered orally at a dose of 5 µg/kg/day for 5 days. At the two weeks-follow-up examination, a significant regression in the mammary glands size and a cessation of milk production were observed. In conclusion, hyperplasic fibroepithelial formations in the mammary glands of a young cat that was brought to our clinic were successfully cured endogenously by surgical method and exogenously by medical drug administration.
