[A case of muscular and canal of nuck involvement by endometriosis]. / Un cas de localisation d'endométriose musculaire et du canal de nuck.

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.

[Imaging of benign ovarian tumors]. / L'imagerie des tumeurs bénignes de l'ovaire.

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.
