Overview

Labyrinthitis
Labyrinthitis is inflammation of the inner ear structures involved in hearing and balance. It can cause sudden dizziness or vertigo, problems with balance, nausea, vomiting, and sometimes hearing loss or ringing in the ear. Symptoms may begin abruptly and can be severe. The condition is often associated with an infection or another inflammatory process affecting the inner ear.
Pheochromocytoma
Pheochromocytoma is a rare tumor that develops from specialized cells of the adrenal glands and can cause excessive release of epinephrine and norepinephrine. These hormones affect heart rate, metabolism and blood pressure. The tumor usually develops in the adrenal gland but can occasionally occur outside it. Episodes may cause severe or recurring headaches, sweating, rapid or pounding heartbeat and high blood pressure. Most pheochromocytomas are not cancerous, although a small number can be malignant.

Diagnosis

Labyrinthitis
Labyrinthitis is diagnosed from the pattern of dizziness, balance problems, hearing symptoms, and medical history together with an examination. The ears and nervous system are assessed to look for other causes of vertigo. Hearing tests may be performed when hearing loss is present. Additional balance testing or brain imaging may be needed when symptoms are severe, unusual, or suggest another neurological condition.
Pheochromocytoma
Diagnosis begins with a medical history and physical examination, particularly when episodes of headache, sweating, palpitations or high blood pressure suggest excess catecholamine production. Blood or urine testing can measure catecholamines and related substances such as metanephrines. Imaging studies may then be used to locate the tumor, including CT or MRI of the abdomen and, in selected cases, specialized nuclear imaging such as an MIBG scan. Genetic evaluation may be considered when the history suggests an inherited condition.

Prevention

Labyrinthitis
There is no guaranteed way to prevent labyrinthitis, but reducing the risk of infections may help. Good hand hygiene, avoiding close contact with people who have contagious respiratory infections, and keeping recommended vaccinations up to date can reduce some infectious triggers. Prompt treatment of significant ear infections and medical assessment of sudden hearing loss or severe vertigo are also important.
Pheochromocytoma
There is no established way to prevent most pheochromocytomas because many develop without a preventable cause. When a hereditary syndrome is present, genetic counseling and appropriate screening of affected families can help identify tumors earlier. Close relatives of people with inherited pheochromocytoma may benefit from evaluation and periodic testing. People who have previously been treated successfully should continue follow-up testing because the tumor can sometimes return.

Risk Factors

Labyrinthitis
Risk factors may include a recent viral respiratory infection, another ear infection, or inflammation affecting the inner ear. People with conditions that increase susceptibility to infection may have a higher risk of complications. Certain inflammatory or autoimmune disorders can also be associated with inner-ear inflammation. A history of ear disease may contribute to susceptibility.
Pheochromocytoma
Risk factors include having a family history of pheochromocytoma or an inherited syndrome associated with adrenal or endocrine tumors. People with certain hereditary conditions may have a higher likelihood of developing one or more tumors. Pheochromocytoma can occur at any age but is most commonly diagnosed during early to middle adulthood. Close relatives of people with hereditary disease may also need evaluation because some cases are inherited.
