Article Synopsis
- Cerebral vasospasm (CV) after tumor resection is uncommon but linked to serious complications, prompting a study into its risk factors.
- A review of 61 studies found that CV occurs more in males with an average age of 47.3, commonly after resection of posterior fossa tumors, especially schwannomas and pituitary adenomas.
- Symptoms usually include altered mental status and weakness, often occurring within the first two weeks post-surgery, and the condition can lead to high mortality rates and significant long-term deficits.
Looking Beyond the Anterolateral Skull Base with Frontotemporal Dural Fold Unlocking and Extradural Clinoidectomy: A Series of 17 Cases Deciphering the Translation from a Cadaver to Real, and Real to Pathologically Distorted Anatomy.

Department of Neurosurgery, SGPGIMS, Lucknow, Uttar Pradesh, India.
Objective: This article aims to discuss the surgical nuances and major adjustments necessary in unlocking the frontotemporal dural fold (FTDF) and extradural anterior clinoidectomy (EDAC) in actual cases, allowing translation from the cadaveric to a clinical scenario.
Materials And Methods: We retrospectively reviewed the technical details of 17 procedures over 8 years, where both the initial steps (FTDF unlocking and EDAC) were performed. Lesions involving or extending to the anterolateral skull base, like the suprasellar cistern, optico-carotid cistern, interpeduncular cistern, petrous apex, and cavernous sinus, were included.
Hemorrhagic schwannoma of the trochlear nerve: Case report and a review of the literature.

Department of Neurosurgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.
Background: Schwannomas of the trochlear nerve with the absence of systemic neurofibromatosis are considerably uncommon, especially complicated by intra-tumoral hemorrhage. Due to the lack of typical clinical manifestations and imaging findings, a definite diagnosis of trochlear schwannomas before surgery is particularly difficult.
Case Presentation: We report the case of a 64-year-old female patient who presented with a unilaterally intermittent headache of 2-month duration and without a remarkable neurological deficit at admission.

Epidermoid tumors are slow-growing, benign, congenital lesions. They commonly arise in the cerebellopontine angle, fourth ventricle, suprasellar region, or spinal cord. Symptoms may include hearing loss, facial pain, and headaches.
