History of Present Illness: Patient is a 19 y.o., White female right-handed student who presents with sudden onset of diplopia, disequilibrium, tingling of extremities, posterior neck and lower back discomfort, and distorted speech. She states that last evening she began with diffuse odd feeling of dizziness and tingling in her hands and throughout her extremities but was otherwise normal. She and her mother felt that this was likely due to vertigo from recent URI. However, upon arising this morning she noticed considerable diplopia and progressive worsening of symptoms.

She denies significant headache, chest pain, shortness of breath, nausea, vomiting, fever, chills, dysuria, incontinence or visual field cuts. She has not had previous similar symptoms. She is up-to-date on her childhood vaccines and has received 2 doses of Moderna COVID-19 vaccine completed on 4/24/21. ED evaluation revealed what appeared to be significant bilateral abducens paralysis. Imaging was pursued with MRA of the brain, MRI of the brain and CT angiogram of the head and neck which have revealed no significant pathology. Case was discussed with the on-call neurologist who felt the patient should be admitted for further evaluation and would like an MRI of the brain with contrast for further investigation. She will be admitted with internuclear opthalmoplegia and other neurologic  symptoms for further evaluation and treatment.   Vaccinations: Pneumovax- Does not meet criteria to receive.
