case_images: She was diagnosed to have PAP on CT chest and bronchiole alveolar lavage (BAL) in another hospital 7 months earlier and was on treatment with corticosteroids (Fig. 1a). MRI brain showed a T2 hyperintense lesion in the left superior parietal lobe (Fig. 1b). Histopathology revealed a suppurative lesion with neutrophils and mononuclear cells (Fig. 1c). Amidst the necrotic material were seen delicate septate hyphae with acute angle branching (Fig. 1d-f). The hyphae were highlighted by Gomori methenamine silver (GMS) and periodic acid Schiff (PAS) stains (Fig. 1g). There were grey to blue green colonies and microscopy showed conidia (fruiting bodies) (Fig. 1h).
