Shining Forth

A woman in her third trimester is brought into the emergency department for a "scary fall." Unfortunately, no one knows her and she has not been receiving prenatal care. She is an African American teenager who is clearly in the third trimester of pregnancy, but dating is unknown. Bystanders witnessed her falling with brief flexion of her arms, upward deviated eyes, extension of the back, arms, and legs, and crying out. This was followed by brief, violent muscle contractions, cyanosis, foamy salivation at the mouth, and loss of bladder control. All of this resolved by itself within one minute. Currently, she is confused, complaining about sore muscles and a headache. She is hypertensive. A urinalysis shows proteinuria.
