title: An unexpected cause of orbital apex syndrome in an immune-competent elderly male.
abstract: Invasive aspergillosis causing orbital apex syndrome (OAS) in an immune-competent individual is a very rare phenomenon, scarcely reported in medical literature. A 68-year-old male presented with progressive loss of vision in the right eye, starting after a cataract surgery. Neurological examination suggested OAS. Imaging was suggestive of mass lesion causing destruction of ethmoid bone. Biopsy of the lesion could not be done initially in view of its proximity to the major neuro-vascular bundle in the orbital apex and cavernous sinus and the major risk involved in the procedure relative to its yield. There was no response to empirical therapy with antibacterials, steroids or Amphotericin-B. Gradually the mass increased in size and was amenable to biopsy. Endoscopy guided biopsy revealed invasive aspergillosis. Switching over to voriconazole lead to successful management. This case highlights the importance of early diagnosis and selection of an appropriate antifungal therapy in the management of invasive aspergillosis.
