title: Post endodontic Aspergillosis in an immunocompetent individual.
abstract: Non-invasive aspergillosis in immunocompetent individuals subsequent to post endodontic treatment can involve the maxillary antrum. An early and accurate diagnosis will aid in prompt and effective treatment. A 35 year old female patient reported with a painful nasomaxillary swelling. Previous records revealed the failure of the endodontic treatment of maxillary left second premolar which was subsequently extracted. Root piece was accidently left behind which resulted in a painful nasomaxillary swelling. The extraction socket was curetted and tissue was sent for histopathological examination, which revealed abundant septate fungal hyphae with numerous spores characteristic of Aspergillus. The patient showed marked improvement in the symptoms with systemic itraconazole at 3 months follow up and complete resolution occurred within 6 months. Inclusion of aspergilloma infections in the differential diagnosis is advocated when patients present with post-endodontic nasomaxillary swelling.
