Dizziness is a prevalent symptom in the general population, accounting for a
considerable share of physician office visits, and most causes are clinically
treatable. It is also a common indication for neuroimaging studies, in order to
identify a specific etiology and exclude surgical causes. Here, we illustrate
the main peripheral and central causes of dizziness, discussing their possible
differential diagnoses, as well as their most important image aspects.
Hearing disorders are usually unilateral and are more common in women. They can
be congenital or acquired, and hearing loss is categorized as sensorineural,
conductive, or mixed. The onset of hearing loss can be progressive or sudden,
and it is a common reason for seeking medical attention. In this context,
computed tomography and magnetic resonance imaging have assumed critical roles
in the search for an etiological diagnosis and in guiding the therapeutic
approach. In this pictorial essay, we illustrate the common causes of hearing
loss, discussing the possible differential diagnoses and highlighting the most
relevant imaging findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
