Fig. 8

T2 fat suppressed coronal (A) and T1W coronal (B) images show evidence of extensive hypertrophy of turbinates on left side with opacification of bilateral maxillary and left ethmoidal sinuses with heterogeneous T2 hyperintense contents showing foci of signal void consistent with fungal elements. There is involvement of left orbit in contiguity with left ethmoid sinus in the form of bulky superior oblique, medial and inferior recti muscles with orbital fat stranding. Preseptal swelling and proptosis of left orbit were also present (not shown here). C, D T2W fat suppressed axial images showing complete opacification of sphenoid sinus in addition to above-mentioned findings along with hyperintensity in peri-alveolar (white arrow), pterygoid muscle (yellow arrow), pterygopalatine fossa (black arrow) and infratemporal fossa (red arrow) with corresponding enhancement on post contrast images (E–G T1 post contrast images). Post contrast images also show black turbinate sign. H: Microphotograph from debrided material showing black coloured aseptate fungal hyphae seen in the necrotic slough likely to be mucormycosis (GMS stain X400).
