This is an axial T1 MRI with contrast demonstrating a glomus jugulare tumor growing out of the left jugular foramen. Three cranial nerves traverse the jugular foramen – the glossopharyngeal (CN IX), vagus (CN X) and accessory (CN XI) nerves – and these nerves can be unilaterally affected in the setting of a glomus tumor.
