Magnetic resonance imaging characteristics of glioblastoma of the optic pathway during adulthood. [PDF]

Radiol Case Rep, 2023
Glioma has been previously known as the most common adult brain tumor. Glioma of the optic pathway is predominated by low-grade neoplasms. High-grade glioma in adults is extremely rare. In this study, we present the case of a 46-year-old male patient who

Evaluation of preoperative visual pathway impairment in patients with non-functioning pituitary adenoma using diffusion tensor imaging coupled with optical coherence tomography

Frontiers in Neuroscience, 2023
ObjectiveOptic chiasma compression and associated visual impairment induced by a non-functioning pituitary adenoma (NFPA) is commonly assessed by the optic disk and retina but is inadequate to understand the entire visual pathway impairment.

A pilot study of combined optical coherence tomography and diffusion tensor imaging method for evaluating microstructural change in the visual pathway of pituitary adenoma patients

BMC Ophthalmology, 2022
Background RNFL thickness measured by optical coherence tomography (OCT) and visual pathway measured by diffusion tensor imaging (DTI) can be used to predict visual field recovery, respectively. However, the relationship between RNFL thickness and visual
