Abstract

Rapidly progressing bilateral hearing loss may indicate intracranial metastatic malignancy. MRI and CT imaging can provide useful information on symptom etiology, and as with this coronal CT image of the sinuses and anterior skull base revealing a right ethmoid/cribriform mass (arrow), accessible areas for timely diagnostic biopsy may be identified.
