OBJECTIVES: This article describes magnetic resonance imaging (MRI) findings in 3 cases of @entity2257 ( @entity2257 ). METHODS: Clinical and MRI manifestations of 3 @entity1 with @entity2257 were evaluated. High b value diffusion-weighted and dynamic contrast-enhanced images were performed. The size, shape, site of origin, and signal intensity (SI) of MRI findings were evaluated. RESULTS: All @entity1 (age range, 37-47 years; mean age, 40 years) had a chief complaint of atypical @entity548 with no history of pregnancy. In 2 cases, cytology of the endometrium was positive, and pathological analysis of curettage specimens indicated @entity4348 . The MRI revealed an endometrial polypoid mass arising from the upper corpus (50%) or lower uterine segment (50%). Except for 1 @entity5 that seemed to invade the myometrium of the uterine wall due to its irregular margin, all @entity5 were well circumscribed. On T2-weighted MRI scans, the SI of the @entity5 was homogenous and marginally hyperintense, and contained markedly hyperintense @entity7905 . On T1-weighted images, all the @entity5 were isointense relative to the myometrium, and in 1 case, a number of @entity7905 showed high SIs. In a dynamic contrast-enhanced study, solid portions other than the @entity7905 showed contrast enhancement in the arterial phase and demonstrated a washout pattern or plateau pattern in the late phase. All @entity5 demonstrated high SIs on diffusion-weighted images. CONCLUSIONS: Differentiating @entity2257 from other @entity1204 may still pose difficulties, especially when the @entity5 seems to invade the myometrium on MRI. Comprehensive clinical information about the @entity1 including age, pathological assessment of the endometrium, and MRI findings should be essential to provide indication for a diagnosis of @entity2257 .
