A Unique Case of an Aggressive Gangliocytic Paraganglioma of the Filum Terminale

Case Reports in Surgery, Volume 2016, Issue 1, 2016., 2016
Paragangliomas are rare neuroendocrine tumors that are mostly found in the head and neck. Even less common are gangliocytic variant paragangliomas of the spine for which there are only 7 other documented cases in the literature. We report a case of gangliocytic paraganglioma of the sacral spine in a 68‐year‐old man.

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

Surgery of Glomus Jugulare Tumors [PDF]

Skull Base, 2003
The treatment of choice for glomus jugulare tumors is still controversial. High rates of morbidity, incomplete resection, and the aggressive behavior of these tumors are the main arguments for advocates of primary radiotherapy. However, constant refinements in skull base techniques have made complete resection of these lesions a realistic goal.
