Conclusions: We conclude that neck imaging should be carried out for patients with persistent paroxysmal positional vertigo following diagnostic and/or therapeutic maneuvers.
Objective: It is sometimes complicated to diagnose patients with vertigo that is transiently induced by head and neck positioning. Neck-vestibular diseases also induce vertiginous sensation with head and neck movement and need to be ruled out for the diagnosis of benign paroxysmal positional vertigo (BPPV).
Patients And Methods: Two elderly female patients visited our hospital with complaints of transient vertigo induced by Dix-Hallpike positioning, suggesting posterior canal BPPV. We carried out gadolinium-enhanced neck MRI in both these cases.
Results: The positional nystagmus was not clearly observed or vertiginous sensation did not show any decay during repeated vestibular examination in either case. These cases were finally diagnosed as spinal cord intradural extramedullary tumor (C3-C4) by means of neck MRI.

Background: Cerebellar infarcts are encountered commonly in clinical practice; however, they are likely to be misinterpreted. They cannot be adequately evaluated on scales such as the National Institute of Health Stroke Scale (NIHSS), which can have fatal consequences.
Aim: To evaluate the baseline features, prognosis, and 6-month survival in patients with cerebellar stroke.

Dizziness is an extremely common, yet complex neurological symptom that reflects a disturbance of normal balance perception and spatial orientation. Dizziness is a non-specific, catch-all term commonly used by patients to describe a wide array of symptoms, including a sensation of motion, weakness, light-headedness, unsteadiness, emotional upset and depression. The national 1-year prevalence of dizziness is around 50%, accounting for 4% of emergency department presentations and 1% of primary care consultations in South Africa.

Auditory manifestations from multiple sclerosis (MS) are not as common as the well-recognized sentinel exacerbations of optic neuritis, partial myelitis, motor weakness, vertiginous episodes, heat intolerance, and eye movement abnormalities. This paper discusses four cases of auditory changes, secondary to MS, and describes the first case, to our knowledge, of palinacousis, the perseveration of hearing, despite cessation of the sound stimulus. For each we characterize the initial complaint, the diagnostic work up, and ultimately, underscore the individualized treatment interventions, that allowed us to achieve a remission in all four cases.

Vertigo is a sensation of movement that results from disorders of the inner ear balance organs and their central connections, with aetiologies that are often benign and sometimes serious. An individual who develops vertigo can be effectively treated only after a correct diagnosis of the underlying vestibular disorder is reached. Recent advances in artificial intelligence promise novel strategies for the diagnosis and treatment of patients with this common symptom.
