Article Abstract
Background: Isolated primary central nervous system lymphoma arising from anterior visual pathway is very rare.
Patient Presentation: A 76-year-old immunocompetent previously healthy man presented bilateral decreased visual acuity in 1 month. Pituitary magnetic resonans imaging (MRI) showed a lobulated mass with homogeneous enhancement after gadolinium administration that arising from optic chiasm suggested that inflammatory disease or an optic glioma. The patient underwent an extended endoscopic endonasal transsphenoidal surgery. Postoperative course and outcomes were wonderful. Histopathological diagnosis was diffuse large B-cell lymphoma. The patient underwent investigations for systemic lymphomatous involvement, did not detect any evidence of systemic disease.
Conclusion: In this case, we claimed that differential diagnoses of anterior visual pathway lesions are difficult because of similarity of lesions on clinical and radiological examinations. Biopsy is essential for these lesions. As a biopsy technique, endoscopic endonasal transsphenoidal approach is safer and more effective than open procedures.
Objective: This study aims to summarize the clinical characteristics of skull base osteoradionecrosis (ORN) with the internal carotid artery (ICA) involvement and to distill the key surgical techniques that can enhance the protective measures for ICA.
Methods: We conducted a retrospective, observational study over a six-year period from February 2017 to May 2023. We included patients who were diagnosed with osteoradionecrosis with invasion of the internal carotid artery and collected their demographic information, pathology results, complication rates, ect.
Rapid diagnosis of cerebrospinal fluid (CSF) leaks is critical as endoscopic endonasal skull base surgery gains global prominence. Current clinical methods such as endoscopic examination with and without intrathecal injection of fluorescent dye are invasive and rely on subjective judgment by physicians, highlighting the clinical need for label-free point-of-care (POC). However, a viable solution remains undeveloped due to the molecular complexity of CSF rhinorrhea mixed with nasal discharge and the scarcity of specific biomarkers, delaying sensor development.
Context: Pituitary Neuroendocrine Tumors are rare in children, but challenging, implying the two purposes to cure the child, and preserve pituitary function. In this paper, we describe our population of children who underwent endoscopic endonasal resection of a pituitary adenoma, in Lille University Hospital.
Patients And Methods: Between 2007 and 2021, all children undergoing EEN surgery for pituitary adenoma were included.
Objectives: To determine the incidence of postoperative cerebrospinal fluid (CSF) leaks after endoscopic endonasal transsphenoidal surgery (EETS) for pituitary adenomas without sellar floor reconstruction (SFR).
Methods: This retrospective observational study was conducted at Department of Neurosurgery, Punjab Institute of Neurosciences (PINS), Lahore, Pakistan from January, 2018 to December, 2022. It is a non-probability based consecutive case series.
