Figure 6: Stage IB1 squamous cervical carcinoma in a 51-year-old woman with radical hysterectomy (A) T2-weighted axial MR images show as 2.7 cm lobulated mass (star) on posterior lip of uterine cervix with no disruption of peripheral rim. The maximum diameter of the lesion is measured 2.7cm (arrowhead) on the T2-weighted sagittal image. At histopathological finding, bilateral parametrial lesion was found. MRI stage T1b (≤ 4 cm) was underdiagnosed as final pathologic stage T2b.
