Proptosis secondary to a solitary plasmacytoma of the sphenoid bone: a case report on a rare skull base tumour

open access: yesEgyptian Journal of Neurosurgery, 2022
Background Plasmacytomas of the skull base are not commonly encountered in clinical practice, with few reported cases in the literature. They form part of the spectrum of plasma cell neoplasms and are classified as a solitary bone plasmacytoma if arising

Monocular visual loss in a disseminated colorectal malignancy—A case report of a rare skull base metastasis

open access: yesRadiology Case Reports, 2023
Neoplasms of the orbit may be primary, secondary (infiltration from the adjacent structures), or metastatic (from distant structures). It can be divided into 3 histologic categories: benign, benign but locally aggressive, and malignant.

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

A RARE LOCALIZATION OF INTRAOSSEOUS HEMANGIOMA: CASE REPORT

open access: yesSabiad, 2022
Hemangiomas are defined as benign neoplasms originating from vascular endothelial tissue. Intraosseous hemangiomas are very rare and account for less than 1% of bone tumors. They are mostly seen in vertebras, skull bones and long bones.

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain

open access: yesAdvanced Materials, EarlyView.
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Indium(111) pentetreotide single photon emission computed tomography (In-111 pentetreotide SPECT): a new technique to evaluate somatostatin receptors in chordomas [PDF]

open access: yes, 2005
Chordomas are rare neoplasms originating along the neuraxis. Although they do not usually show cytological atypia, metastases have been reported in 30 per cent of cases.

From Rigid to Soft Robotic Approaches for Neuroendoscopy

open access: yesAdvanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
