Occupational CNS aspergillosis in an immunocompetent individual a diagnostic challange.

We report here a case of primary CNS aspergillosis in an immunocompetent person who was initially diagnosed as a case of meningioma, and had a history of working in an area with excessive ongoing construction. He had no other primary focus of infection anywhere in the body. He was timely diagnosed and broad spectrum antifungals were started immediately. MATERIAL AND METHODS: The brain biopsy and pus sampleas were subjected to direct microscopy using KOH mount and lactophenol cotton blue (LPCB) stain and culture on Sabourad's Dextrose Agar in Microbiology laboratory. Later patient was started on fluconazole and caspofungin. RESULTS: Thin, hyaline, septate hyphae on direct microscopy and growth of Aspergillus flavus on SDA culture were observed. The patient improved only with antifungals, without surgery. DISCUSSION: This case study highlights the importance of keeping the differential diagnosis of Aspergillus spp. in mind even in individuals with no immunodeficiency. The immunocompetent individuals have better prognosis and if timely diagnosed, can be treated even without surgery. The prevalence of aspergillus spores at construction and demolition sites makes it an important public health issue, hence precautions must be advocated at these sites.
