B38.4
Coccidioidomycosis meningitis
Clinical Classification Guidelines
Medical Intelligence & Overview
Coccidioidomycosis meningitis is a serious, rare complication of coccidioidomycosis, also known as Valley Fever. This fungal infection is caused by the inhalation of spores from the Coccidioides fungi, which are primarily found in soil in southwestern United States, parts of Mexico, Central America, and South America. While most people infected with Coccidioides develop mild symptoms or no symptoms at all, some may experience a dissemination of the infection to the central nervous system, leading to meningitis. Recognized by its ICD-10 code B38.4, this condition requires prompt medical attention due to its potentially life-threatening nature.
Causes & Symptoms
Clinical Causes: Inhalation of airborne spores of Coccidioides fungi from contaminated soil Dissemination of the infection from the lungs to the meninges (membranes surrounding the brain and spinal cord) Increased risk in immunocompromised individuals, such as those with HIV/AIDS, organ transplant recipients, or patients on immunosuppressive therapy
Key Symptoms: Persistent headache Neck stiffness Sensitivity to light (photophobia) Altered mental status or confusion Nausea and vomiting Seizures in severe cases Fever and chills (less common than in primary pulmonary coccidioidomycosis)
Diagnostic & Treatment
Diagnosis Path: Diagnosing coccidioidomycosis meningitis involves a combination of clinical assessment and laboratory tests. Physicians may perform lumbar puncture to analyze cerebrospinal fluid (CSF), looking for signs of fungal infection. Laboratory tests include:
Treatment Protocols: Treatment of coccidioidomycosis meningitis primarily involves long-term antifungal therapy. The main antifungal agents used include:
