[Uncommon aspects of mediastinal teratoma. CT X-ray and MRI study].
CT and MRI features of a multicystic mediastinal teratoma, which was surgically and pathologically confirmed, are presented. CT found 4 cystic tumors of mediastinum with water density content and thick capsule. One kyste contained a fat density area and peripheric calcifications. MRI showed will defined high signal intensity on Spin-echo T1 weighted images. CT and MRI are not reliables in predicting or excluding adherence to adjacent structures. The particularity of this case was the presence of a communication between the anterior right cyst and the posterior left one. This communication passed by the transverse sinus of pericardium.
