title: An unusual case of a pituitary fossa aspergilloma in an immunocompetent patient mimicking infiltrative tumour.
abstract: Sellar aspergillosis is a rare infection commonly mistaken for a pituitary tumour. We present a rare case of pituitary fossa Aspergillus fumigatus mycetoma in an immunocompetent 90-year-old female, who presented with headaches. Magnetic resonance imaging scans demonstrated an enhancing pituitary fossa mass that appeared to infiltrate the sphenoid sinus, suggestive of an invasive tumour. Stereotactic trans-sphenoidal resection confirmed localized A. fumigatus infection. The abscess was debrided and the dura was left intact. Her headaches resolved post-operatively and she was treated with voriconazole. This indicates that aspergilloma should be considered as a differential for an unexplained pituitary lesion even in elderly immunocompetent patients.
