a Post-therapy WBI scan showed uptake in left submandibular area misinterpreted as salivary gland activity, b follow-up post-therapy WBI scan revealed disease progression with increased uptake in submandibular region and increase in number and intensity of pulmonary lesions, c SPECT/CT images show iodine avid pterygoid muscles metastasis. d Whole body18F FDG-PET/CT coronal images show intense FDG uptake by left temporalis and pterygoid muscles indicating muscle metastases, e trans-axial images show increased FDG uptake by left temporalis muscle and f trans-axial images show increased FDG uptake by left pterygoid muscles
