Transient mononeuropathies show symptoms that are evident only with the motion that originally damaged the nerve , whereas the symptoms of fixed mononeuropathies are more persistent.
What is the difference between mononeuropathy and polyneuropathy?
The main difference between mononeuropathy and polyneuropathy is that mononeuropathy refers to damage of a single nerve, whereas polyneuropathy refers to damage of multiple nerves. Both, however, are types of peripheral neuropathy. The accumulation of multiple mononeuropathies, known as mononeuritis multiplex, may at times be difficult to differentiate from polyneuropathy.
How do you diagnose mononeuropathy?
When diagnosing mononeuropathy, a review of medical history and physical examination, including extensive neurological assessment, are necessary. Consideration of symptoms and examination findings may suggest specific mononeuropathies, but if the clinical diagnosis is inconclusive, further investigation is needed. Electrodiagnostic testing, a method of evaluating the electrical activity of muscles and nerves, is often suggested to help reveal conditions that cannot be detected with physical examination alone. This method also offers the ability to localize the nerve injury, assess its severity, and estimate the prognosis.

How does the Ulnar nerve work?
The ulnar nerve passes close to the surface of the skin at the elbow. The nerve is easily damaged by repeatedly leaning on the elbow or by hitting the elbow (funny bone). Sometimes the nerve is damaged by an abnormal bone growth in the area. The ulnar nerve, if damaged and swollen, may be squeezed (compressed) as it passes through a narrow passageway at the elbow (the cubital tunnel). The resulting disorder is called cubital tunnel syndrome. (The ulnar nerve passes through the cubital tunnel as it runs from the upper arm to the wrist and hand.)

What Is Mononeuropathy?
If you have been told that you have mononeuropathy, it means that you have a single nerve that is not functioning the way that it should.

Mononeuropathy multiplex is defined as nerve lesions in two or more named nerves in separate parts of the body.
Which vasculitides have the highest incidence of mononeuropathy multiplex?
Among systemic vasculitides, PAN has the highest incidence of mononeuropathy multiplex. Because some nerves are more vulnerable to ischemia, the distribution of nerve infarction is not random. In one series of 94 cases of vasculitic neuropathy, the peroneal nerve or division was involved in 76%, the ulnar nerve in 28%, the tibial nerve in 11%, and the median nerve in 9% [ 58 ]. In general, the peroneal nerve is most often affected in the lower limb and the ulnar nerve is most commonly involved in the upper limb. The peroneal nerve has a watershed zone of relatively poor perfusion in the midthigh, and the ulnar nerve has a watershed zone in the mid–upper arm. On neurological examination, localized impairment of pain and temperature sensation dominates that of large fiber sensory modalities [ 59 ]. Localized weakness is also common. Hyporeflexia or areflexia is usually distal.
Which nerves are affected by mononeuritis multiplex?
Mononeuritis multiplex is usually a length-dependent neuropathy. The longest nerves in the lower extremities are affected, including the peroneal nerve and sural nerve (more than 80% of cases), followed by the tibial nerve (38% to 50%), and then nerves in the upper extremity, including the ulnar nerve (35%), median nerve (35%), and radial nerves (25% to 40%). 2
Is a cutaneous biopsy necessary for vasculitic neuropathy?
The diagnosis of vasculitic neuropathy often requires a high index of suspicion by relying on manifestations that are common to the vasculitides ( Table C27-5 ). Cutaneous nerve biopsy is often necessary for final diagnosis. The yield of nerve biopsy in identifying vasculitic findings improves when nerve sampling is guided by the clinical and EDX findings and when a muscle biopsy is also obtained. Commonly biopsied nerve and muscle combinations include the sural nerve and gastrocnemius muscle or the superficial peroneal nerve and peroneus brevis muscle.
What are the symptoms of mononeuropathy?
Signs and symptoms depend on which nerve is involved, and may include: Difficulty focusing your eyes, double vision or aching behind one eye. Sometimes mononeuropathy occurs when a nerve is compressed. Carpal tunnel syndrome is a common type of compression neuropathy in people with diabetes.
What is proximal neuropathy?
Proximal neuropathy (diabetic polyradiculopathy) Instead of affecting the ends of nerves in the feet, legs, hands and arms, like peripheral neuropathy, proximal neuropathy affects nerves in the thighs, hips, buttocks or legs.
