Extracranial venous abnormalities, especially jugular venous outflow disturbance, were originally viewed as nonpathological phenomena due to a lack of realization and exploration of their feature and clinical significance. The etiology and pathogenesis are still unclear, whereas a couple of causal factors have been conjectured. The clinical presentation of this condition is highly variable, ranging from insidious to symptomatic, such as headaches, dizziness, pulsatile tinnitus, visual impairment, sleep disturbance, and neck discomfort or pain...

During the past several years, the rapid development of neuroimaging techniques has contributed greatly in the noninvasive imaging studies of tinnitus. The aim of the present study was to explore the brain anatomical alterations in patients with right-sided unilateral pulsatile tinnitus (PT) in the early stage of PT symptom using voxel-based morphometry (VBM) analysis. Twenty-four patients with right-sided pulsatile tinnitus and 24 age- and gender-matched normal controls were recruited to this study. Structural image data preprocessing was performed using VBM8 toolbox...

Schneiderian papillomas (ISP) of the middle ear are uncommon conditions, with only 45 cases published within literature. They are locally aggressive tumours, with a high rate of recurrence and associated malignancy. We present a rare case of a 53-year-old man presenting with unilateral pulsatile tinnitus, otorrhoea, aural fullness, pruritis and hearing loss. Angiography was employed to exclude a glomus tumour and the patient underwent a modified radical mastoidectomy. Tissue samples confirmed a histological diagnosis of ISP of the middle ear...

Three-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) can reliably detect dural arteriovenous fistula (dAVF); however, TOF source images should be checked in cases with low-flow dAVFs. A 69-year-old woman reported intractable pulsatile tinnitus after head trauma. It was difficult to diagnose dAVF using conventional MRA, but it was confirmed using a TOF source image. Cerebral angiography revealed a dAVF with a small shunted pouch draining into the sigmoid sinus, accompanying the arterial jet flow...

OBJECTIVES: Finding the underlying cause for pulsatile tinnitus can be challenging. We aimed to determine the incidence of arteriovenous shunts, i.e., arteriovenous malformations (AVMs) or dural arteriovenous fistulas (dAVFs), in patients referred for catheter angiography (digital subtraction angiography [DSA]). Furthermore, we assessed which clinical features were predictive for the presence of such a lesion. STUDY DESIGN AND METHODS: Fifty-one patients with pulsatile tinnitus, who were referred to us for DSA to exclude an arteriovenous shunt, were enrolled, prospectively...

OBJECTIVE Aggressive dural arteriovenous fistulas (dAVFs) with cortical venous drainage (CVD) are known for their relatively high risk of recurrent neurological events or hemorrhage. However, recent natural history literature has indicated that nonaggressive dAVFs with CVD have a significantly lower prospective risk of hemorrhage. These nonaggressive dAVFs are typically diagnosed because of symptomatic headache, pulsatile tinnitus, or ocular symptoms, as in low-risk dAVFs. Therefore, the viability of stereotactic radiosurgery (SRS) as a treatment for this lesion subclass should be investigated...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

Arteriovenous malformations (AVMs) are fast-flow vascular malformations that mostly occur in the head and neck region. They are typically progressive and their spontaneous regression is almost never seen. We present a case with pulsatile tinnitus and a parapharyngeal AVM. It resolved completely after diagnostic catheter-based angiography alone.

Pulse-synchronous tinnitus is rare, and it almost always points towards a vascular pathology. We encountered a 56 year old patient presenting with 3 month history of right side tinnitus and was found to have a sigmoid sinus aneurysm after initial imaging. The patient was successfully managed using dual endovascular access and stent placement across the aneurysm, with a subsequent complete symptomatic relief. Description on endovascular management of sigmoid sinus aneurysm is not infrequent in the literature...

Tinnitus is the perception of sound in the absence of a corresponding external acoustic stimulus, resulting in an estimated prevalence of 10% to 15% in adults. Tinnitus may be classified as pulsatile (PT) or continuous (non-PT), and may be subjective (heard only by the patient) or objective (also audible to the examiner). PT is usually related to vascular causes and is pulse synchronous (coinciding with the patient's heartbeat). PT is much less common affecting approximately 4% of patients with tinnitus, but unlike non-PT, usually has a specific identifiable cause...

To the best of our knowledge, only 2 cases of a simultaneous contralateral vestibular schwannoma (VS) and middle ear paraganglioma (MEP) have previously been reported in literature. We report the third case observed in a 43-year-old male, who presented with an 11-year history of right-sided hearing loss and a 1-year history of left-sided pulsatile tinnitus. A magnetic resonance imaging (MRI) showed a VS on the right side and computer tomography (CT) identified a Fisch type A1 paraganglioma on the left side...
