MR of neurologically symptomatic newborns after vacuum extraction delivery.

We present the MR findings in three neurologically symptomatic newborns after vacuum extraction delivery. The lesions included subdural hematomas, one tentorial hematoma, and one intracerebellar hemorrhage. One patient had hydrocephalus that required shunting. We propose that the visualized abnormalities are probably the result of vertical stress leading to laceration of bridging veins, venous sinuses, and/or venous hemorrhagic infarctions.
