RT Journal Article SR Electronic T1 Prenatal MR diagnosis of a thick corpus callosum. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1918 OP 1920 VO 17 IS 10 A1 F Rypens A1 P Sonigo A1 M C Aubry A1 A L Delezoide A1 F Cessot A1 F Brunelle YR 1996 UL http://www.ajnr.org/content/17/10/1918.abstract AB Fetal sonography revealed cerebral, facial, and genitourinary abnormalities, prompting MR at 33 weeks' gestational age. Cerebral MR confirmed a thickened corpus callosum and showed open sylvian fissures, abnormal gyri in the frontal lobes, and presumed neuronal heterotopias. An abortion was performed at 34 weeks' gestational age, and pathologic findings corresponded well to the MR manifestations.
