The acute vestibular syndrome (AVS) is characterized by the rapid onset of vertigo, nausea/vomiting, nystagmus, unsteady gait, and head motion intolerance lasting more than 24 hours. We present 4 patients with AVS to illustrate the pearls and pitfalls of the Head Impulse, Nystagmus, Test of Skew (HINTS) examination.
