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.

MRI assessment of pelvic floor dysfunction is still fairly recent. It is a fast expanding field, owing to its safety and simplicity when compared to other imaging modalities. The possibility of direct dynamic imaging is a decisive input, and it can be coupled to a clinical examination at the magnet. The most widely used sequences are T2 weighted fast TSE or fast gradient echo, in the sagittal and frontal planes. Dynamic MRI of the pelvic floor allows pre-operative staging of prolapse, detection of hidden prolapses and assessment of muscle trophicity. Post-operatively it allows assessment of surgical results and failures or recurrences.

We report the case of a patient with infrarenal abdominal aortic aneurysm with mural thrombus covering the ostium of a patent inferior mesenteric artery (IMA). The IMA was supplied via flow from an accessory aneurysmal lumen within the mural thrombus that filled retrogradely from the aorta. This unusual pattern, associated with calcifications within the thrombus, raised the possibility of chronic aortic dissection.

Purpose: To assess the value of imaging in the differential diagnosis of erosive intervertebral osteochondrosis (EIVO) versus infectious discitis (ID)., Materials and Methods: Twelve cases of EIVO and 30 cases of ID were reviewed to define the usefull signs for differential diagnosis on plain films, CT, and MR., Results: No single sign is sufficient, but the association of several signs is suggestive of EIVO: discal vacuum phenomenom, well-defined sclerosis and erosions of vertebral endplates, high signal strip surrounding low signal of vertebral endplates on T1-weighted images., Conclusion: Imaging is helpful in difficult differential diagnosis of EIVO versus ID.
