[A case of Mullerian duct cyst torsion combined with bladder cancer].

The diagnosis and treatment of a patient with Mullerian duct cyst torsion combined with bladder cancer were retrospectively analyzed. The patient received an open abdominal operation with right accessory resection plus pelvic adhesion release, and conducted microscopic examination for the bladder under general anesthesia. The results of histopathological examination confirmed the diagnosis of Mullerian duct cyst and papillary urothelial carcinoma at low level. After surgery, the patient received chemotherapy and follow-up observation, and all the indices for the patient were normal and no obvious discomfort. Although the final diagnosis of Mullerian duct cysts is based on histopathological examination, ultrasonography, CT scan and MRI can also detect it. Most of the Mullerian duct cysts are benign, and surgical excision is safe and effective.
