Rhabdomyosarcoma: a 12-year-old boy with a large left neck mass. T1-weighted image shows a large enhancing left infratemporal mass, with invasion of middle cranial fossa and associated right-sided pharyngeal displacement (yellow circles). The mass shows restricted diffusion on DWI (red circles) with an a low ADC value, suggesting malignant etiology. PET-CT shows hypermetabolic activity in the left infratemporal region (blue circle), compatible with a malignant mass. This is a typical appearance of rhabdomyosarcoma in this age group. DWI: diffusion-weighted imaging; ADC: apparent diffusion coefficient; PET-CT: positron emission tomography computed tomography.
