An 8-year-old female red-eared slider (Trachemys scripta elegans) was presented to our clinics with appettite loss for 3 months, dyspnea and weight loss. After clinical examination, complete blood counts, radiography, ultrasonography and computed tomography has been used for diagnosis. All diagnostic tests with detailed clinical examination clearly showed that the patient had follicular stasis. Plastronotomy was performed to enter the coelomic cavity under general anesthesia. At least 20 Follicles were removed with oophorectomy and the plastronotomy gap was closed. The patient was hospitalized for a week and then discharged with full recovery. The patient has died 10 days after discharging.
