Glomus Jugulare-MRI




"Contrast-enhanced MRI demonstrates enhancing soft-tissue masses at characteristic locations; these findings are important for diagnosis. Nonenhanced MRI can demonstrate glomus tumors, but the demonstration of a strongly enhancing mass is typical in the diagnosis of a glomus tumor. Contrast-enhanced imaging can show intense tumor enhancement, which again, is a key finding in the diagnosis. In addition, a salt-and-pepper fine vascular pattern can be seen in the tumors; this finding is suggestive of intrinsic tumor neovascularity and is particularly well demonstrated on T2-weighted images. Direct coronal imaging can show tumoral relationships to adjacent structures such as the brainstem and skull base, and deep cervical soft-tissue structures extraordinarily well depicted."

how would we differentiate an endolymphatic sac tumour from a glomus jugulate on HRCT temporal bone and on MRI.
