Positron emission tomography-computed tomography fusion, contrast-enhanced computed tomography scan, and contrast magnetic resonance imaging axial (upper) and coronal images (lower) showing large lobulated, expansile, heterogeneously enhancing, moderate-to-high grade fluorodeoxyglucose avid left sinonasal cavity mass lesion with extensive and advanced locoregional disease

FDG PET-CT with side-by-side analysis of the contrast MRI of neck revealed large lobulated, expansile, heterogeneously enhancing, moderate-to-high grade FDG avid mass lesion occupying entire left side of sinonasal cavity, nasopharynx with cranial extension up to pterygopalatine fossa and masticator space through left pterygomaxillary fissure, as well as minimal extension into extraconal compartment of left orbit and also involving left inferior orbital fissure [Figure 1].
Positron emission tomography-computed tomography fusion and contrast-enhanced computed tomography scan coronal images (upper and middle rows) shows well-defined, heterogeneously low-grade fluorodeoxyglucose avid solid hypodense lesions at corticomedullary junction of the right kidney with maximum intensity projection images in lower penal
