Chest computerized tomography (CT) revealed a patchy ground-glass appearance in both lungs, in favor of COVID-19 (Figure 1).
Axial T2-weighted images without contrast administration show (a) mucosal thickening and secretion in the right maxillary sinus and a retention cyst in the left maxillary sinus and (b) mucosal thickening and secretion in the right ethmoid sinus with a lesser degree in the left ethmoid sinus.

The brain magnetic resonance imaging (MRI) was in favor of sinusitis (Figure 2).

Axial paranasal CT images without contrast administration showing (a) mucosal thickening and secretion in the right maxillary sinus and a retention cyst in the Lt maxillary sinus and (b) mucosal thickening and secretion in the right ethmoid sinus with a lesser degree in the Lt ethmoid sinus.

The paranasal sinus (PNS) CT scan showed osteomeatal obliteration associated with opacification of bilateral maxillary, ethmoid, frontal, and the Rt sphenoid sinus, suggestive of sinusitis (Figure 4).
(a) Paranasal sinus mucosa with heavy infiltration of acute and chronic inflammatory cells, H&E stain (x100). (b) Paranasal sinus mucosa with the area of necrosis and hypha which are in favor of the zygomycetes group of fungi, surrounded by polymorphonuclear leukocytes, H&E stain (x200).

Coronal paranasal CT images without contrast administration. Soft tissue window images: (a) area of increased density in the inferior aspect of right orbit suggestive of orbital inflammation. Mucosal thickening in the right maxillary sinus and a retention cyst in the Lt maxillary sinus was also demonstrated. Bone window image: (b) thinning in the medial aspect of the inferior orbital wall at the right side, suggestive of a small bony erosion (compared to the Lt one).
