Résumé
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 ß-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.
