There are no other neurological symptoms, what is the SINGLE most likely diagnosis

A 35 year old woman complains of dizziness. She awoke in the morning with a mild headache and the dizziness started when she sat up in bed. She felt that the room was spinning for a few minutes. If she is at rest the spinning stops but is aggravated again by movement. There are no other neurological symptoms. What is the SINGLE most likely diagnosis

A. Brainstem stroke
B. Benign paroxysmal positional vertigo
C. Meniere’s disease
D. Vestibular neuronitis
E. Acoustic neuroma

All of the above options are popular topics in PLAB 1. Meniere’s disease would usually involve tinnitus, deafness, and increased ear pressure in the case stem. Vestibular neuronitis, while similar to Meniere’s does not have hearing loss. Acoustic neuroma as it grows into the cerebellopontine angle would involve cranial nerves V, VII, VIII; therefore, you would have a variation of symptoms involving these three nerves. Between options A and B, the symptoms in the case stem would not spontaneously resolve for option A. Benign paroxysmal positional vertigo Presentation: - Can be preceded by infections - Vertigo on turning over in bed, lying down, or sitting up from supine position Diagnosis: - Hallpike’s Manoeuvre positive Treatment: - Mostly spontaneous resolution with exacerbations
