A 58-year-old man with recently diagnosed coccidioidal meningitis presented to the ED with a five-day history of headache, photopsia, blurred vision, and worsening encephalopathy. His coccidioidal meningitis had responded well to fluconazole therapy, but three weeks later, he developed acute symptomatic worsening. Unfortunately, his clinical worsening coincided with Arizona's worst seasonal West Nile Virus (WNV) outbreak. He was ultimately found to have WNV neuroinvasive disease. Concurrent coccidioidal and WNV neuroinvasive diseases have not been described in the literature. Fortunately, he improved quickly to his normal baseline without neurologic deficits with supportive therapy for his WNV neuroinvasive disease and remains on lifelong antifungal therapy for coccidioidal meningitis.
