Background: Intracranial fungal granulomas occur by extension from contiguous structures or by hematogenous dissemination from lungs. Isolated granulomas without any obvious source of infection are extremely uncommon. Objective: To describe isolated intracerebral Aspergillus spp. granuloma without any obvious source of infection. Materials and Methods: We analyzed clinical, radiological and pathological features of isolated intracerebral aspergillus granulomas diagnosed in our institution between 1986 and 2006. The chest X-ray and paranasal sinus (PNS) X-rays were reviewed. Fungal stainings were done on histological sections. Results: We identified eight patients with Aspergillus spp. intracerebral granulomas (six males, two females). There were no predisposing risk factors. The chest and PNS X-rays were normal. On computerized tomography all were heterogeneously enhancing lesions with perilesional edema. Pre or perioperative diagnosis was never made. Histological studies revealed granulomas with minimal fibrosis and giant cells and septate hyphae of Aspergillus spp. on fungal stains. Two patients died of postoperative complications and two patients relapsed. Conclusion: Isolated intracerebral aspergillus granulomas are rare and pose a diagnostic challenge. Fungal granulomas should be considered in the differential diagnosis of intracerebral inflammatory pathologies.
