Figure/Graphic 1a-f: Skull-base metastases
Magnetic resonance images of patients with skull-base metastases causing Greenberg’s 5 syndromes. (a) T1-weighted, gadolinium-enhanced MR axial image in a 60-year-old woman with skull-base metastasis from colon cancer presenting with visual disturbance and double vision (orbital syndrome). (b) T1-weighted, gadoliniumenhanced MR axial image in a 41-year-old man with skull-base metastasis from lung cancer presenting with diplopia (parasellar syndrome). (c) T1-weighted, gadoliniumenhanced MR axial image in a 72-year-old woman with skull-base metastasis from breast cancer presenting with trigeminal neuralgia (middle-fossa syndrome). (d) T1-weighted, gadolinium-enhanced MR axial image in a 49-year-old woman with skullbase metastasis from melanoma presenting with dysphagia (jugular foramen syndrome). (e, f) Pre- and post-contrast-enhanced axial MR images in a 70-year-old man with skull base metastasis from prostate cancer presenting with severe occipitalgia and dysarthria (occipital condyle syndrome).
