Identifying the aetiology of sudden acute abnormal involuntary movements in a primigravid

A 20-year-old primigravid experienced sudden stiffening of the neck, upper and lower extremities and trunk associated with joint pains. She was generally well before hospital admission with no history of attacks, except for her inflammatory bowel disease that was treated more than a year ago. During physical examination, the patient manifested neck flexion deviated to the right, deviation of the eyes downward and to the right, spooning of the upper extremities, exhibition of milkmaid's grip, extension of both lower extremities and jerky speech. She also showed uncontrollable tremors of the neck and occasional flailing of upper extremities. Her preliminary laboratory tests were within normal range. It was worth noting here that her family's medical history was unremarkable. In this article, the process of arriving at the final diagnosis and treatment would be discussed.
