As the internal jugular vein, glossopharyngeal, vagus and spinal accessory nerves pass extracranially through the JF; the presence of the glomus jugulare tumor may compress these neurovascular structures thus leading to a loss of hearing and paralysis of the lower cranial nerves (Sethi et al.).
At surgery, a large loculated cyst was found that had to be dissected from the internal carotid artery, internal jugular vein, and the vagus and accessory nerves. The cyst measured 90 x 50 x 33 mm, and it contained thick, yellow, inspissated material (figure 2,A).
These benign and slowly growing tumors can arise from the vagus, glossopharyngeal, and spinal accessory nerves; lesions at these different sites are not always distinguishable from each other, either clinically or on imaging.
