Fig. 2From: Assessment of perineural spread in advanced cutaneous squamous cell carcinomas treated with immunotherapyMagnetic resonance imaging (MRI) demonstrating tumour RECIST 1.1 response with concordant perineural spread (PNS) response: (A) All images MRI post-contrast T1 fat saturation (FS). Coronal MRI images demonstrate: (A) Baseline. Arrow indicates a thickened and enhancing right maxillary division trigeminal nerve (V2). B < 5 months image: diminished size and enhancement of the right maxillary division trigeminal nerve. C > 10 months image: no enhancement of the right maxillary division trigeminal nerve with normal size. Axial MRI images demonstrate: (D) Baseline. Enhancing left malar mass cutaneous squamous cell carcinoma (CSCC). E < 5 months, diminished enhancement and mass. F > 10 months (28 months), resolved enhancement and massBack to article page
