diagnosis and treatment of a functional follicular cyst in a persian queen cat: a case report

in the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old persian queen cat is described. in response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. trans-abdominal ultrasonography examination showed 2 cysts  in the left ovary of the queen. serum estrogen assay indicated elevated level of 17 β-estradiol concentration (105 pg/ml). however, progesterone concentration was normal (0.3 ng/ml). accordingly, the queen was diagnosed with functional follicular cysts. the queen was treated with an administration of hcg intra-muscularly. thirty (30) days after the administration of hcg, an injection of equine chorionic gonadotropin (ecg) (50 iu) was given intra-muscularly. natural mating was done with a fertile persian tom cat. in conclusion, it seems that treatment of functional follicular cysts can be applied to preserve fertility in cats.
