Intensely enhancing mass splaying left ECA & ICA...Carotid body tumour (paraganglioma)

Slow growing, non tender, with restricted vertical mobility. CT & Angio suggestive of arising between Internal & external carotids with Splaying- Lyre's sign. D/D- Carotid body tumour Glomus Jugulare Shwannoma Lymphnode mass. (Unlikely) Inv- MRI for typical appearance on T1 & T2 weighted images, for differentiation between the lesions. FNAC & Biopsy better to be "Avoided".
