Uterine malignant lymphoma rare, no special signs, no special physical examination, usually showed vaginal bleeding (7%), perineal discomfort (40%), vaginal discharge (20%), diffuse uterine enlargement, cervical cytology Negative, serum LDH levels can be increased. The authors report 4 cases of uterine malignant lymphoma confirmed by pathology, the earliest and the only involved internal organs. 1 case of MR showed extensive uterine symmetry increased, T_2WI on the binding band and cervical matrix normal low signal disappears, the vagina is widely involved, the bladder wall seems to be invading lesions T_1WI was low on the letter
