Increased Nuchal Translucency and Early Growth Retardation Related to Confined Placental Mosaicism of Trisomy 16 in a Dichorionic Twin.

Confined placental mosaicism (CPM) of trisomy 16 is related to intrauterine growth restriction; however, its association with increased nuchal translucency (NT) has not been sufficiently studied. We report the first case involving a diagnosis of CPM for trisomy 16 in a dichorionic twin. Increased NT (3.

Temporary homonymous hemianopsia after epidural blood patch.

We describe a case in which homonymous hemianopsia developed abruptly following an epidural blood patch procedure. The procedure was performed in a patient complaining of post-dural puncture headache after an emergency Cesarean section under spinal anesthesia. Computed tomography and magnetic resonance imaging demonstrated that air bubbles had moved from the prepontine and premedullar cisterns toward the left retrochiasmal region.
