Pregnancy-induced acute neurologic emergencies and neurologic conditions encountered in pregnancy.

Neurologic complications and conditions associated with pregnancy are rare. Frequently, presenting symptoms of neurologic conditions are nonspecific and can overlap with normal symptoms of pregnancy. As a result, clinical assessment can be insufficient to differentiate symptoms of a normal pregnancy from a neurologic disorder. It is imperative that the radiologist have a basic familiarity with the most common neurologic conditions encountered in pregnancy. The most commonly imaged acute and nonemergent disorders will be described, including eclampsia, cerebrovascular disease including cerebral venous thrombosis, postpartum cerebral angiopathy, multiple sclerosis, tumors, Bell palsy, Guillain-Barré syndrome, and pituitary disorders.
