Plattenepithelkarzinom des Mundbodens

Imaging of

the sublingual and submandibular spaces. Squamous cell carcinoma involving the left sublingual space. Infiltrative lesion centred within the left sublingual space, which demonstrates heterogenous intermediate to high signal on T2-weighted MRI (a) and isointensity compared with adjacent musculature on T1-weighted MRI (b). c Post-contrast axial and d coronal T1-weighted MR images reveal heterogenous enhancement (arrow)

the sublingual and submandibular spaces. Squamous cell carcinoma involving the left sublingual space. a Axial contrast-enhanced CT image shows a homogenously enhancing lesion within the left sublingual space (arrow), b which demonstrates 18F-fluorodeoxyglucose (FDG) avidity on PET/CT
