Figure 4. (a) Transverse non-fat saturated T1 weighted MR image before and (b) fat-saturated image after administration of contrast agent at the level of the vocal cords showing right-sided soft tissue ulceration (b, arrowhead) and tissue swelling on the left side (b, arrows), not allowing exclusion of tumour recurrence. Both (c) b1000 image and (d) apparent diffusion coefficient (ADC) map do not show a restrictive focal lesion, supporting the diagnosis of laryngeal necrosis without tumour recurrence. (e) Five and (f) 10 times magnified histopathological sections show necrotic tissue (N), and stromal tissue with reactive changes (S); multiple neutrophils and giant cells are visible, suggesting profound inflammatory reaction. No tumoral tissue was found.
