| The diagnosis of labyrinthitis is based on clinical evaluation, rather than any test. The viral of preceding viral illness and acute onset symptoms like [[Dizziness causes|dizziness]],nausea and vomiting with gait impairment suggestive of labyrinthitis. No any specific diagnostic test are available.
| |
|
| |
| ===Diagnostic Study of Choice===
| |
| Neuroimaging, generally MRI is done to rule out other acute causes for symptoms that includes cerebellar [[Hemorrhage intracranial|hemorrhage]] and brainstem infraction. If MRI not available, CT scan can be done to look for alternative diagnosis.
| |
| ===History and Symptoms===
| |
| The hallmark feature of labyrinthitis is sudden onset severe vertigo. A positive history of preceding viral infection and vertigo with gait instability is suggestive of labyrinthitis. The common symptoms of labyrinthitis include dizziness, gait abnormality, nausea and vomiting.
| |
|
| |
| ===Physical Examination===
| |
| Common physical examination findings of labyrinthitis include [[nystagmus]] (unilateral-horizontal mostly), positive head impulse test(unable to maintain visual fixation on rapid turning of head towards the side of lesion), gait instability( tends to fall on side of lesion) and absence of neurological sign and symptoms. Unilateral hearing loss might be present in some cases.

| ===Laboratory Findings===
| |
| There are no diagnostic laboratory findings associated with [[Labyrinthitis (paitent information)|labyrinthitis]].
| |
|
| |
| ===CT scan===
| |
|
| |
| There are no CT scan findings associated with labyrinthitis. However, a CT scan may be helpful to rule out [[differential diagnosis]] like cerebellar hemorrhage/infarction and brainstem infarction.
| |
|
| |
| ===MRI with contrast===
| |
| MRI of inner ear may be helpful in the diagnosis of labyrinthitis. Findings on MRI suggestive of labyrinthitis include abnormal enhancement in membranous [[Labyrinth (inner ear)|labyrinth]] on post-contrast T1WI scan.

The majority of cases of labyrinthitis are self-limited and require only supportive care during acute symptoms.
Supportive therapy for labyrinthitis includes anti-emetics, anti-histamines, anti-cholinergics and benzodiazepines. Glucocorticoids and anti-viral drugs are the mainstay of treatment for labyrinthitis. Vestibular rehabilitation therapy also recommended among all patients who develop labyrinthitis.
