B26.84
Mumps polyneuropathy
Clinical Classification Guidelines
Medical Intelligence & Overview
Mumps polyneuropathy is a neurological condition that develops as a complication of mumps infection. Mumps itself is a contagious viral illness characterized mainly by swelling of the salivary glands, but in some cases, it can affect the nervous system. When mumps impacts multiple peripheral nerves, the result is a condition known as polyneuropathy. This condition can cause a range of neurological symptoms, which may vary in severity depending on the extent of nerve involvement.
Causes & Symptoms
Clinical Causes: Primary mumps infection caused by the mumps virus Immune response to the virus leading to nerve inflammation Post-infectious autoimmune reactions targeting nerve tissues
Key Symptoms: Weakness or numbness in various parts of the body Muscle pain or cramping Difficulty with coordination and balance Sensory disturbances such as tingling or burning sensations Facial weakness in some cases In severe cases, paralysis of affected nerves
Diagnostic & Treatment
Diagnosis Path: Diagnosing mumps polyneuropathy involves a combination of medical history review, physical and neurological examinations, and supportive laboratory tests. Blood tests can detect mumps antibodies indicating recent or past infection. Nerve conduction studies and electromyography (EMG) help to assess nerve function and identify the pattern of nerve involvement. Occasionally, nerve biopsy may be performed, though it is rarely necessary. Differential diagnosis is essential to exclude other causes of polyneuropathy such as diabetes or autoimmune disorders.
Treatment Protocols: Treatment primarily focuses on managing symptoms and supporting nerve recovery. It may include:
