ICD-10: B27.02

ICD-10 code B27.02 refers specifically to Gammaherpesviral mononucleosis with meningitis. This classification falls under the broader category of infectious mononucleosis, which is primarily caused by the Epstein-Barr virus (EBV) and can also be associated with other gammaherpesviruses.

Clinical Description

Overview of Gammaherpesviral Mononucleosis

Gammaherpesviral mononucleosis is characterized by a constellation of symptoms that typically include fever, sore throat, lymphadenopathy (swollen lymph nodes), and fatigue. The condition is often associated with EBV, which is known for its role in infectious mononucleosis, but other gammaherpesviruses can also cause similar clinical presentations.

Symptoms

Patients with gammaherpesviral mononucleosis may experience:
- Fever: Often high and persistent.
- Sore Throat: Severe pharyngitis is common.
- 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, although this is less common.

Meningitis

When meningitis is present, it indicates that the infection has spread to the central nervous system (CNS). Meningitis is an inflammation of the protective membranes covering the brain and spinal cord, which can lead to serious complications. Symptoms of meningitis may include:
- Headache: Often severe and persistent.
- Stiff Neck: Difficulty in bending the neck forward.
- Photophobia: Sensitivity to light.
- Altered Mental Status: Confusion or decreased consciousness.
- Nausea and Vomiting: Commonly associated with increased intracranial pressure.

Diagnosis

The diagnosis of gammaherpesviral mononucleosis with meningitis typically involves:
- Clinical Evaluation: Assessment of symptoms and medical history.
- Laboratory Tests: Blood tests to detect antibodies against EBV or other gammaherpesviruses, and lumbar puncture (spinal tap) to analyze cerebrospinal fluid (CSF) for signs of infection and inflammation.
- Imaging Studies: In some cases, imaging such as MRI or CT scans may be performed to assess for complications.

Treatment

Management of gammaherpesviral mononucleosis with meningitis focuses on supportive care, which may include:
- Hydration: Ensuring adequate fluid intake.
- Pain Management: Use of analgesics for headache and body aches.
- Corticosteroids: In severe cases, corticosteroids may be administered to reduce inflammation.
- Antiviral Therapy: While specific antiviral treatment for EBV is limited, antiviral medications may be considered in certain cases.

Prognosis

The prognosis for patients with gammaherpesviral mononucleosis with meningitis varies depending on the severity of the infection and the timeliness of treatment. Most patients recover fully, but some may experience prolonged symptoms or complications.

In summary, ICD-10 code B27.02 encapsulates a serious manifestation of gammaherpesviral mononucleosis, highlighting the importance of prompt diagnosis and management to mitigate potential complications associated with meningitis.

Gammaherpesviral mononucleosis, specifically coded as ICD-10 B27.02, is a condition primarily associated with infections caused by the Epstein-Barr virus (EBV) and, in some cases, other gammaherpesviruses. This condition can lead to a range of clinical presentations, particularly when it involves complications such as meningitis. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this diagnosis.
