Conservative treatment of a synovial cyst in a golden eagle (Aquila chrysaetos) with triamcinolone acetonide

In human and veterinary medicine, the treatment of synovial cysts involves medical or surgical approach. When medical treatment is chosen, triamcinolone acetonide is one of the most used drugs. In this case, intracystic triamcinolone was administered for the treatment of a non-infectious elbow synovial cyst in a subadult female Golden eagle (Aquila chrysaetos), unable to fly. The bird was brought to a wildlife rescue center after an aerial fight with a conspecific. After the treatment, no clinically detectable adverse effects were noted and there was no recurrence within two weeks. Given the improvement of the clinical conditions and the recovery of flight ability, the animal was released back into the wild 17 days after administration of the drug.
