To learn the common locations of paragangliomas of the head and neck and where they originate. To study the common imaging findings of paragangliomas,
scintigraphy and angiography.
Paragangliomas of the head and neck are rare tumours,
representing <0.5% of all head and neck tumours.
there is a 3:1 female predominance,
with two-thirds of cases being diagnosed between the ages of 40 and 60.
The classic manifestation of a carotid body tumor is a nontender,
enlarging lateral neck mass which is mobile,
pulsatile and associated wiht a bruit.
The jugulare and tympanicum tumors commonly cause pulsatile tinnitus and hearing loss and may cause cranial nerve compression....
Findings and procedure details
Imaging is the primary diagnostic examination for glomus tumors of the head and neck.
Contrast-enhanced computed tomography (CT) scanning,
magnetic resonance imaging (MRI),
scintigraphy and angiography can be performed for proper diagnosis and localization of the tumors. They are divided according to location: Carotid body tumour Glomus tympanicum tumour Glomus jugulotympanicum tumour Glomus jugulare tumour Glomus vagale tumour. Radiographics Features Ultrasound : Useful as the first step in...
Imaging techniques are essential for the management of paragangliomas of the head and neck in order to assess the involvement of adjacent structures,
follow-up and diagnosis of local recurrence.
