Figure 3. (a) Transverse CT image and (b) transverse contrast-enhanced T1 weighted MR image show diffuse thickening and contrast-enhancement of the false vocal cords, without focal nodular mass. Small air bubble adjacent to the right arytenoid can be appreciated (a, arrow). (c) Coronal FDG-PET image shows tracer uptake at the laryngeal level. No asymmetric hyperintensity is revealed by (d) b1000 and (e) the ADC map shows diffuse hyperintensity of the soft tissues at the same level. Histological examination reveals necrosis, inflammation and purulent infiltration, without evidence for tumour recurrence. (f) Detailed histological image shows granulation tissue and inflammatory infiltrate.
