Primary meningioma of jugular foramen is extremely rare, while paraganglioma or nerve sheath tumor are relatively common in jugular foramen. We reported a case of primary meningioma of jugular foramen. A 79-year-old female who had left tinnitus and hearing loss for three month came to the department of otorhinolaryngology. Temporal bone computed tomography scan showed sclerotic change and slightly irregular margins of left jugular foramen with relatively preservation of bony architecture. Temporal bone magnetic resonance image showed well defined homogeneous enhancing mass in left jugular foramen with extension to carotid space on gadolinium enhanced T1 weighted image. Prominent dural tail was also noted. On T2 weighted image, this mass showed intermediated signal intensity with no vascular signal voids. Meningioma was confirmed by pathology. In this article, we describe a case of primary en plaque meningioma of jugular foramen and review image findings of differential diagnosis.
