Primary lymphoma in a 62-year-old woman.. A. US reveals hypoechoic lobulated uterine enlargement, with an anechoic portion. An echogenic endometrial line is not present.. B. Sagittal T1-weighted image shows homogeneous diffuse enlargement of the uterus, with an area of focal high signal intensity. The anterior vaginal wall is thickened.. C. Sagittal T2-weighted image shows a low signal intensity uterus containing a high signal intensity area representing hemorrhagic necrosis. The zonal anatomy of the endometrium, myometrium and endocervix is not preserved, and the junctional zone is indistinct.. D. T1-weighted image after gadolinium administration reveals inhomogeneous, moderate enhancement of the uterus and anterior vaginal wall.. E. On photomicrograph the border between the myometrium and endometrium is blurred by the infiltration of lymphoid tumor cells, and the tumor shows extensive necrosis (H & E).
