A87.2
Lymphocytic choriomeningitis
Clinical Classification Guidelines
Inclusion Terms
- Lymphocytic meningoencephalitis
Medical Intelligence & Overview
Lymphocytic choriomeningitis (LCM) is a viral infection that affects the membranes surrounding the brain and spinal cord, leading to inflammation. It is caused by the lymphocytic choriomeningitis virus (LCMV), which is transmitted primarily through contact with infected rodents. Though relatively uncommon, LCM can cause serious neurological symptoms and requires medical attention for proper diagnosis and management.
Causes & Symptoms
Clinical Causes: Contact with urine, droppings, saliva, or nesting materials from infected mice or hamsters. Inhalation of dust contaminated with virus particles. Less commonly, transmission through organ transplantation or laboratory exposure.
Key Symptoms: Fever Headache Muscle aches Fatigue Nausea and vomiting Stiff neck Sensitivity to light Confusion or disorientation Seizures (in severe cases)
Diagnostic & Treatment
Diagnosis Path: Diagnosis often involves a combination of medical history, symptom assessment, and laboratory tests such as blood tests or cerebrospinal fluid analysis. Detection of specific antibodies to the virus or identification of viral RNA through PCR testing can confirm LCM infection. Imaging studies like MRI may be used to evaluate neurological involvement.
Treatment Protocols: There is no specific antiviral treatment for lymphocytic choriomeningitis. Management typically focuses on relieving symptoms and supporting the body's recovery. Hospitalization might be necessary in severe cases to monitor neurological status and provide supportive care. Rest, hydration, and over-the-counter medications for pain and fever are commonly recommended. In some instances, corticosteroids may be used to reduce inflammation, but this depends on the individual case and clinician discretion.
