Benign endometrial adenofibroma and polyp in patients receiving tamoxifen: findings on transvaginal ultrasonography and magnetic resonance imaging

Cervical tumors

Imaging the cervix for benign and malignant disease can be achieved using transvaginal ultrasound, computed tomography (CT), magnetic resonance imaging, and 18-fluorodeoxyglucose positron emission tomography. The best established role of imaging is in cervical carcinoma where magnetic resonance imaging, CT and increasingly positron emission tomography-CT are the most frequently used imaging modalities. These have a role in staging, treatment selection, recurrent disease, and imaging complications of treatment. Histopathological diagnosis of cervical disorders cannot be made on the basis of imaging alone but certain imaging features may provide an indication as to the underlying diagnosis. We describe the imaging features of some malignant tumor subtypes in which a preoperative diagnosis may alter management. Benign lesions of the cervix are usually detected incidentally or during investigations for dysfunctional vaginal bleeding. We describe the imaging features of the commonly encountered benign cervical lesions.

Adenofibroma of the endometrium protruding into the vaginal cavity: findings on transvaginal ultrasonography, MRI and CT

Adenofibroma is a rare benign biphasic neoplasm that is classified into the mixed epithelial and mesenchymal tumor group. We report the case of a 42-year-old woman with adenofibroma of the endometrium protruding into the vagina. Transvaginal ultrasonography revealed the tumor as an intravaginal mass containing multiple cystic components. Magnetic resonance imaging (MRI) showed a heterogeneous high-intensity mass filling the vaginal cavity on T2-weighted imaging, with a low-contrast enhanced septum identified within the mass on gadolinium-enhanced, T1-weighted imaging. Contrast-enhanced computed tomography (CT) showed a heterogeneous low-attenuating multicystic mass filling the vaginal cavity. Although preoperative diagnosis of this rare tumor is very difficult, the combination of MRI, CT, and ultrasonography offers a useful diagnostic tool.
