ANTENATAL DIAGNOSIS OF CHORIOANGIOMA OF THE PLACENTA - MR FEATURES - CASE-REPORT

We report a case of chorioangioma of the placenta, in which MR finding s were useful in establishing the antenatal diagnosis. Polyhydramnios and a placental tumor that was 5 cm in size were visualized. The tumor had relatively high signal intensities on proton density imaging and T2-weighted imaging and showed partially high intensity signal rims on T1-weighted imaging, especially when using a breath-holding technique . Magnetic resonance imaging has an important role in detection and di agnosis of these lesions, particularly the larger tumors, so that appr opriate steps can be taken to deal with the complications that may acc ompany this tumor.
