Metastatic disease. A patient presenting with rapidly progressive hearing loss underwent MRI. On a heavily T2-weighted image (a) a tumour with an “ice-cream cone” appearance and cystic changes is present on the left. On the right a soft tissue mass is present in the cerebellopontine angle cistern. Follow-up examintation a few months later (b-d) revealed extensive growth of the lesions, which are now evidently closely related to the choroid plexus. Post-contrast images (c, d) show cystic and nodular leptomeningeal metastases in the fossa posterior. CSF analysis showed malignant cells (adenocarcinoma)
