Cauda equina aspergilloma in an immunocompetent individual: A case report.

The authors report an unusual case involving a 70 year old man who came with severe low back pain radiating to both legs, magnetic resonance imaging (MRI) lumbosacral spine reveled nodular spinal intradural lesions involving Cauda equina for which he was operated. Histopathological examination of the operative specimen revealed large granulomas with multinucleate giant cells lining zones of necrosis and within the granuloma numerous septate branching hyphae of Apsergillus spp highlighted by Gomori methenamine silver stains which was suggestive of aspergillosis. There is no reported case of Cauda equina aspergilloma in an apparently immunocompetent person before this.
