RESUMEN
The aim of this pictorial review was to illustrate the normal cervix appearance on T2-weighted images, and give a review of common or less common disorders of the uterine cervix that appear as high signal intensity lesions on T2-weighted sequences. Numerous aetiologies dominated by cervical cancer are reviewed and discussed. This gamut is obviously incomplete; however, radiologists who perform MR women's imaging should perform T2-weighted sequences in the sagittal plane regardless of the indication for pelvic MR. Those sequences will diagnose some previously unknown cervical cancers as well as many other unknown cervical or uterine lesions.

Endometriosis is defined by the presence of endometrial tissue outside the uterine cavity and having the functional property of menstrual bleeding. We report a case of endometriosis involving the abdominal wall muscles and canal of Nuck in a 28 year old woman. Abdominal wall sonography showed a hypoechoic lesion at the rectus abdominis insertion. T1W and T2W MRI images showed a hemorrhagic high signal intensity lesion in the muscle. MRI also showed a similar lesion in the canal of Nuck.

Membranous dysmenorrhea is an unusual clinical entity. It is characterized by the expulsion of huge fragments of endometrium during the menses, favored by hormonal abnormality or drug intake. This report describes a case with clinical, US, and MRI findings before the expulsion. Differential diagnoses are discussed.

US and MRI currently are the best imaging modalities to evaluate pathology of the uterine cervix and vagina. Carcinoma of the cervix is the most frequent indication for imaging. MRI allows preoperative staging of cervical carcinoma based on FIGO classification, and post treatment follow-up. Other uterine cervix diseases are less frequently imaged and include a wide range of entities that most frequently cause increased T2W signal at MR imaging. Pathology of the pelvic floor, vagina, vulva, and perineum also includes a wide range of entities that have seldom been described in the imaging literature.

A positive diagnosis of benign ovarian tumor indicates a laparoscopic approach or a conservative treatment. Benign ovarian tumors are often easy to recognize with non ionizing modalities such as US and MRI. The most common benign ovarian tumors are: mature teratomas including dermoid cysts, tumors in the fibro-thecal group including fibromas and thecomas, benign serous and mucinous tumors (cystadenomas). Apart from ovarian tumors, endometriomas are more commonly extra ovarian, but may involve the ovarian stroma.
