ICD-10: B26.84

Mumps polyneuropathy, classified under the ICD-10-CM code B26.84, is a rare neurological complication associated with mumps infection. Understanding this condition requires a look at both the clinical presentation of mumps and the specific implications of polyneuropathy.

Overview of Mumps

Mumps is a viral infection caused by the mumps virus, which primarily affects the salivary glands, leading to symptoms such as fever, headache, muscle aches, fatigue, and swollen salivary glands (parotitis) [7]. While mumps is often considered a childhood disease, it can affect individuals of any age, particularly those who are unvaccinated.

Mumps Polyneuropathy

Definition and Pathophysiology

Mumps polyneuropathy refers to the involvement of multiple peripheral nerves due to the mumps virus. This condition is characterized by inflammation of the nerves, which can lead to a range of neurological symptoms. The exact mechanism by which the mumps virus causes polyneuropathy is not fully understood, but it is believed to involve an autoimmune response triggered by the viral infection, leading to demyelination and nerve damage [9].

Clinical Presentation

Patients with mumps polyneuropathy may present with various symptoms, including:

• Weakness: Muscle weakness, particularly in the limbs, is common as the peripheral nerves are affected.
• Sensory Changes: Patients may experience numbness, tingling, or pain in the affected areas.
• Reflex Changes: Diminished or absent reflexes may be noted during a neurological examination.
• Autonomic Dysfunction: In some cases, patients may exhibit signs of autonomic nervous system involvement, such as changes in heart rate or blood pressure.

Diagnosis

The diagnosis of mumps polyneuropathy typically involves a combination of clinical evaluation and laboratory tests. Key diagnostic steps include:

• History and Physical Examination: A thorough history of recent mumps infection and neurological symptoms is essential.
• Electromyography (EMG) and Nerve Conduction Studies: These tests help assess the electrical activity of muscles and the conduction speed of nerves, aiding in the diagnosis of neuropathy [8].
• Serological Testing: Detection of mumps-specific IgM antibodies can confirm recent infection with the mumps virus.

Treatment

Management of mumps polyneuropathy is primarily supportive, focusing on alleviating symptoms and promoting recovery. Treatment options may include:

• Corticosteroids: In cases of significant inflammation, corticosteroids may be prescribed to reduce nerve inflammation.
• Physical Therapy: Rehabilitation exercises can help improve strength and function in affected muscles.
• Pain Management: Analgesics or neuropathic pain medications may be used to manage discomfort.

Conclusion

Mumps polyneuropathy, coded as B26.84 in the ICD-10-CM, represents a serious but rare complication of mumps infection. Early recognition and appropriate management are crucial for improving patient outcomes. As vaccination against mumps has become widespread, the incidence of such complications has significantly decreased, but awareness remains important for healthcare providers dealing with cases of mumps and its potential neurological sequelae [6][10].
