Frequency‐Dependent Neural Activity in Patients with Unilateral Vascular Pulsatile Tinnitus

Neural Plasticity, Volume 2016, Issue 1, 2016., 2016
Previous resting‐state functional magnetic resonance imaging (rs‐fMRI) studies have shown that neurological changes are important findings in vascular pulsatile tinnitus (PT) patients. Here, we utilized rs‐fMRI to measure the amplitude of low‐frequency fluctuations (ALFF) in forty patients with unilateral PT and forty age‐, gender‐, and education ...

The Endoscopic Versus Open Approach for Anterior Skull Base Tumors: A Systematic Review of Comparative Outcomes and a Framework for Surgical Selection

Neurology Research International, Volume 2025, Issue 1, 2025.
Background Anterior skull base tumors (ASBTs) pose significant surgical challenges due to their proximity to critical neurovascular structures. Surgical management has evolved with the adoption of both endoscopic and open approaches. This systematic review synthesizes evidence comparing these approaches in terms of complications, outcomes, and ...

Growth Rate Analysis of an Untreated Glomus Vagale on MRI

Case Reports in Otolaryngology, Volume 2016, Issue 1, 2016., 2016
Paragangliomas are slow growing, hypervascular neuroendocrine tumors that develop in the extra‐adrenal paraganglion tissues. Paraganglioma involving the vagus nerve ganglia is termed glomus vagale. The slow growth of head and neck paragangliomas especially in the absence of symptom may obviate the necessity for any active intervention, in which case, a

Dark Blood Contrast‐Enhanced Brain MRI Using Echo‐uT1RESS

Journal of Magnetic Resonance Imaging, Volume 60, Issue 2, Page 789-797, August 2024.
Background The widely used magnetization‐prepared rapid gradient‐echo (MPRAGE) sequence makes enhancing lesions and blood vessels appear bright after gadolinium administration. However, dark blood imaging using T1‐weighted Sampling Perfection with Application optimized Contrast using different flip angle Evolution (T1 SPACE) can be advantageous since ...

Endovascular Approach to Glomus Jugulare Tumors [PDF]

Polish Journal of Radiology, 2018
<b>Background</b>: Paragangliomas are benign neuroendocrine tumors derived from the glomus cells of the vegetative nervous system. Typically, they are located in the region of the jugular bulb and middle ear. The optimal management is controversial and can include surgical excision, stereotactic radiosurgery and embolization.<br /> ...

Incidence of cranial nerve palsy after preoperative embolization of glomus jugulare tumors using Onyx

, 2014
The resection of glomus jugulare tumors can be challenging because of their inherent vascularity. Preoperative embolization has been advocated as a means of reducing operative times, blood loss, and surgical complications.

Evaluation of Linear Accelerator-based Stereotactic Radiosurgery in the Management of Glomus Jugulare Tumors

, 2014
Aims and Background Although mostly benign and slow-growing, glomus jugulare tumors have a high propensity for local invasion of adjacent vascular structures, lower cranial nerves and the inner ear, which may result in substantial morbidity and even ...
