B27.12
Cytomegaloviral mononucleosis with meningitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Cytomegaloviral mononucleosis with meningitis is a rare but serious condition caused by the cytomegalovirus (CMV), which leads to inflammation of the brain's meninges. This dual infection combines symptoms of mononucleosis, a contagious illness, with meningitis, an inflammation of the membranes covering the brain and spinal cord. Recognizing this condition early is crucial for management and care.
Causes & Symptoms
Clinical Causes: Primary infection with cytomegalovirus, often transmitted through bodily fluids such as saliva, blood, urine, semen, or breast milk Reactivation of dormant CMV in individuals with weakened immune systems Possibility of infection through organ transplantation or blood transfusions Vertical transmission from mother to fetus during pregnancy
Key Symptoms: Fatigue and weakness Fever and chills Headache and neck stiffness Sensitivity to light (photophobia) Nausea and vomiting Confusion or altered mental state Dizziness or vertigo Muscle aches Swollen lymph nodes, particularly in the neck Sore throat
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a thorough medical history and physical examination, focusing on neurological findings and lymphadenopathy. Laboratory tests can include blood tests to detect CMV antibodies, polymerase chain reaction (PCR) testing for viral DNA, and cerebrospinal fluid (CSF) analysis obtained via lumbar puncture. Imaging studies like MRI or CT scans might be used to assess inflammation and rule out other causes of meningitis.
Treatment Protocols: Treatment generally involves antiviral medications such as ganciclovir or valganciclovir to control CMV infection. Supportive care, including hydration, rest, and managing symptoms like fever and pain, is essential. In severe cases, hospitalization might be necessary, especially if neurological symptoms worsen or complications arise. Regular monitoring of the patient's neurological status and response to treatment is important for optimal recovery.
