Condylar metastasis from adenocarcinoma. OPT (a) with osteolytic ill-defined lesion of the mandibular condyle (arrow). b Sagittal PET/CT image shows high metabolism with SUV = 12 (arrow). c Axial, contrast-enhanced, fat-saturated T1-weighted image. The infiltrative, bulky lesion invades the condyle (arrow), the internal pterygoid muscle (dashed arrow) and part of the parotid gland (thin arrow). d Intraoperative view. Extensive condylar involvement. e Histology (haematoxylin-eosin stain, original magnification 80×): large atypical polygonal cells, some with several nuclei (arrow)
