ICD-10: B27.11

Cytomegaloviral mononucleosis with polyneuropathy, classified under ICD-10 code B27.11, represents a specific manifestation of infectious mononucleosis caused by the cytomegalovirus (CMV). This condition is characterized by a combination of symptoms associated with mononucleosis and neurological complications, particularly polyneuropathy.

Clinical Description

Cytomegalovirus (CMV) Infection

Cytomegalovirus is a common virus that belongs to the herpesvirus family. It is often asymptomatic in healthy individuals but can cause significant illness in immunocompromised patients, newborns, and those with underlying health conditions. CMV is primarily transmitted through bodily fluids, including saliva, blood, urine, and sexual contact.

Mononucleosis Symptoms

Infectious mononucleosis, commonly referred to as "mono," is typically characterized by:
- Fever: A high fever is often one of the first symptoms.
- Sore Throat: Severe throat pain due to swollen tonsils.
- Lymphadenopathy: Swelling of lymph nodes, particularly in the neck and armpits.
- Fatigue: Profound tiredness that can last for weeks.
- Rash: Some patients may develop a rash.

Polyneuropathy

Polyneuropathy refers to a condition that affects multiple peripheral nerves, leading to symptoms such as:
- Numbness and Tingling: Often in the hands and feet.
- Weakness: Muscle weakness that can affect mobility.
- Pain: Sharp or burning pain in the affected areas.
- Loss of Coordination: Difficulty in maintaining balance and coordination.

In the context of CMV infection, polyneuropathy may arise due to the virus's impact on the nervous system, potentially leading to inflammation and damage to peripheral nerves.

Diagnosis and Coding

The diagnosis of cytomegaloviral mononucleosis with polyneuropathy involves clinical evaluation, including:
- Medical History: Assessment of symptoms and potential exposure to CMV.
- Laboratory Tests: Blood tests to detect CMV antibodies and confirm active infection.
- Neurological Assessment: Evaluation of nerve function, which may include nerve conduction studies and electromyography to assess the extent of polyneuropathy.

The ICD-10 code B27.11 specifically denotes cases where polyneuropathy is present alongside the typical symptoms of cytomegaloviral mononucleosis, indicating a more complex clinical picture that requires careful management.

Treatment Considerations

Management of cytomegaloviral mononucleosis with polyneuropathy typically focuses on:
- Symptomatic Relief: Pain management and treatment of fever and sore throat.
- Supportive Care: Ensuring adequate hydration and rest.
- Monitoring Neurological Symptoms: Regular follow-up to assess the progression of polyneuropathy and adjust treatment as necessary.

In severe cases, particularly in immunocompromised patients, antiviral medications may be considered to manage the CMV infection more aggressively.

Conclusion

ICD-10 code B27.11 encapsulates a significant clinical condition where cytomegaloviral mononucleosis is complicated by polyneuropathy. Understanding the symptoms, diagnostic criteria, and treatment options is crucial for healthcare providers to effectively manage this condition and improve patient outcomes. Regular monitoring and supportive care are essential components of treatment, especially for those experiencing neurological complications.
