We present computed tomography (CT) and magnetic resonance imaging (MRI) features of a very rare case of a primary epidermoid tumor of the jugular foramen (JF). A 45-year-old male patient presented with gradually progressive vertigo and tinnitus. CT and MRI scans revealed a 3.5 cm right-sided JF tumor with characteristic bright signal (restricted diffusion) on diffusion-weighted MRI (DWI). DWI may be useful in accurately differentiating the lesion from other cystic neoplasms of the JF. We describe the imaging features of intracranial epidermoid and JF tumors and discuss its differential diagnosis.

Keywords: Computed tomography, congenital cholesteatoma, jugular foramen, magnetic resonance, primary epidermoid.
