Mononeuritis Multiplex
Updated: Mar 23, 2009
Introduction
Background
Mononeuritis multiplex is a painful asymmetric asynchronous sensory and motor peripheral neuropathy involving isolated damage to at least 2 separate nerve areas. Multiple nerves in random areas of the body can be affected. As the condition worsens, it becomes less multifocal and more symmetric. Mononeuropathy multiplex syndromes can be distributed bilaterally, distally, and proximally throughout the body.1,2
Mononeuritis multiplex actually is a group of disorders, not a true distinct disease entity. Typically, the condition is associated with (but not limited to) systemic disorders such as diabetes, vasculitis, amyloidosis, direct tumor involvement, polyarteritis nodosa, rheumatoid arthritis,3 systemic lupus erythematosus, and paraneoplastic syndromes. Mononeuritis multiplex also may be associated with Lyme disease, Wegener's granulomatosis, Sjögren syndrome, cryoglobulinemia, hypereosinophilia, temporal arteritis, scleroderma, sarcoidosis, leprosy,4 acute viral hepatitis A, and acquired immunodeficiency syndrome (AIDS).5,6
Pathophysiology
Mononeuritis multiplex involves damage to at least 2 separate nerve areas. This condition can become progressively worse over time. The damage to the nerves involves destruction of the axon (ie, the part of the nerve cell that is analogous to the copper part of a wire), thus interfering with nerve conduction. Common causes of damage include a lack of oxygen from decreased blood flow or inflammation of blood vessels. Approximately 33% of cases originate from unidentifiable causes.7
Frequency
United States
The actual incidence of mononeuritis multiplex in the United States is not known due to the widely varied underlying pathologies that may lead to the disorder. The primary disease process often is so dominant that the symptoms of mononeuritis multiplex simply are attributed to the initial disease and remain undiagnosed.
International
Same as frequency in the United States (see above).
Mortality/Morbidity
If the cause of mononeuritis multiplex is identified early and is successfully treated, full recovery is possible. The extent of disability varies, from no disability to partial or complete loss of function and movement.
Race
No race predilection is known for mononeuritis multiplex.
Sex
Mononeuritis multiplex exhibits equal incidence in men and women.
Age
Age of onset for mononeuritis multiplex depends on the patient's age at occurrence of the associated disease process; however, this condition does tend to occur in older patients with relatively mild or even unrecognized diabetes for unknown reasons.
Clinical
History
A detailed and complete medical history is vitally important in determining the possible underlying cause of mononeuritis multiplex. Pain often begins in the low back or hip and spreads to the thigh and knee on one side. The pain usually is characterized as deep and aching with superimposed lancinating jabs that are most severe at night. Individuals with diabetes typically present with acute onset of unilateral severe thigh pain that is followed rapidly by weakness and atrophy of the anterior thigh muscles and loss of the knee reflex. Other possible symptoms that may be reported by the patient include the following:
- Numbness
- Tingling
- Abnormal sensation
- Burning pain - Dysesthesia
- Difficulty moving a body part - Paralysis
- Lack of controlled movement of a body part
Physical
Loss of sensation and movement may be associated with dysfunction of specific nerves. Examination reveals preservation of reflexes and good strength except in regions more profoundly affected. Some common findings of mononeuritis multiplex may include the following (not listed in order of frequency):
- Sciatic nerve dysfunction
- Femoral nerve dysfunction
- Common peroneal nerve dysfunction
- Axillary nerve dysfunction
- Radial nerve dysfunction
- Median nerve dysfunction
- Ulnar nerve dysfunction
- Tardive ulnar palsy
- Peroneal nerve palsy
- Autonomic dysfunction - The part of the nervous system that controls involuntary bodily functions, such as the glands and the heart
Causes
Mononeuritis multiplex most commonly is associated with diabetes mellitus and multiple nerve compressions.
