Table 1.
Patient group with PT according to final diagnosis based on DSA and MRI.
Fig 1.
46 year old male patient with left sided PT since 6 months.
TOF (A), ce-MRA (B) and DSA (C): dAVF I by Cognard/Merland classification of the sigmoid sinus.
Fig 2.
53 year old patient with right-sided pulsatile tinnitus and severe headache since 4 months.
DSA (A), TOF (B), ce-MRA (C) and T2 (D): DAVF IIa by Cognard/Merland classification at the sigmoid/transverse sinus.
Fig 3.
64 year old male patient with PT on the left ear since 4 months.
DSA of the left carotid artery shows a left sided dAVF Type III Cognard/Merland classification (A). The venous drainage leads direct into a trapped left sided transverse sinus into a cortical vein, which is not dilatated (B).
Fig 4.
42 year old patient with left sided PT for one year.
A: Superselective angiographic microcatheter injection before preoperative embolization with particles. B: MRI ce-T1 fs shows a Glomus tympanicum paraganglioma: enhancing mass in loco typico.

Diagnostic Work-Up for patients with PT.
DSA is only recommended in patients with a finding of a vascular pathology in MRI.
