Coexisting sellar Rathke cleft cyst and planum sphenoidale meningioma: illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, Stanford University School of Medicine, Stanford, California.
Background: The co-occurrence of Rathke cleft cysts (RCCs) and meningiomas in the sellar and parasellar regions represents an exceedingly rare clinical entity. Achieving maximal resection through a single operative approach while minimizing adverse events is challenging, often necessitating multiple surgical approaches, as suggested by previous reports.
Observations: The authors report the case of a 49-year-old female with a history of kidney transplant who presented with headaches and was diagnosed with coexisting RCC and meningioma in the sellar and planum sphenoidale regions, respectively.
Parasellar region meningiomas with optic canal (OC) invasion: Correlation between the degree of decompression of the OC and the improvement of visual acuity.
Clin Neurol Neurosurg
December 2024
"Città della Salute e della Scienza" University Hospital, Skull Base and Pituitary Surgery Unit, Turin, Italy; "Città della Salute e della Scienza" University Hospital, Neurosurgery Unit, Turin, Italy.
Purpose: To evaluate the correlation between the degrees of circumferential decompression of the optic canal (OC) and the improvement of visual acuity in patients with parasellar meningiomas (PMs) with optic canal invasion.
Methods: This is a monocentric retrospective study conducted at author's institution. The visual acuity was evaluated preoperative and at 3-months after surgery with Snellen acuity test.
Diagnostic considerations of tumors of the sellar region according to their geometry and vector growth.

Servicio de Neurocirugía, Hospital "Hermanos Ameijeiras", La Habana, Cuba. Electronic address:
Introduction: Sellar and parasellar tumors are frequent lesions in neurosurgical practice, highlighting pituitary adenomas, craniopharyngiomas, and sellar tubercle meningiomas. The clinical manifestations are similar, however; There are imaging aspects that differentiate them.
Objective: Show imaging aspects of tumors in the sellar and parasellar region that guide their histopathological diagnosis.
Endonasal surgery high-risk carotid injury timeout checklist: implementation, institutional protocol and experience.
Acta Neurochir (Wien)
November 2024
Pacific Neuroscience Institute, Providence Saint John's Health Center, 2125 Arizona Ave, Santa Monica, CA, 90404, USA.
Objective: Carotid artery injury is a rare, but major complication of endonasal operations. The morbidity and mortality of such a complication can be mitigated by preparedness and a clear plan set in place to address the hemorrhage expeditiously. This study examines the implementation of such a carotid injury timeout checklist and demonstrates its effectiveness in a patient with possible arterial injury.

Article Synopsis
- Radiomics uses quantitative methods to analyze medical images, revealing hidden patterns that may serve as noninvasive biomarkers in skull base oncology.
- Applications mainly focus on three tumor types: meningioma, sellar/parasellar tumors, and vestibular schwannomas, with investigations covering areas like tumor detection, classification, grading, and prognosis.
- Despite advancements and the use of deep-learning methods, challenges such as small sample sizes and limited diversity in data hinder broader adoption, highlighting the need for multi-institutional collaboration to validate radiomic technologies.
