Surgical management of giant pituitary adenomas: institutional experience and clinical outcomes of 94 patients.

Background: Giant (with a diameter of at least 40 mm and a volume of at least 10 cm) pituitary adenomas (GPAs) are intricate tumors that pose considerable difficulty for surgical removal. While endoscopic transsphenoidal surgery (ETS) is a commonly employed technique for these destructive tumors, its effectiveness may be restricted in cases where invasion into multiple compartments is present, leading to limited resection.

Methods: A retrospective review was conducted on the clinical records of 94 patients diagnosed with GPAs who had undergone surgical resection from 2014 to 2022.

Risk Factors for Progression in Vestibular Schwannomas After Incomplete Resection: A Single Center Retrospective Study.

The risk factors for progression in vestibular schwannomas (VSs) after incomplete resection (IR) remain to be elucidated. The purpose of this study was to investigate the risk factors for progression in remnant VSs after surgery. From January 2009 to January 2018, 140 consecutive patients who underwent IR of VSs suboccipital retrosigmoid approach in our institution were retrospectively analyzed.

Calcified extra-axial cavernous malformation arising from lower cranial nerves: A case report and literature review.

Rationale: Extra-axial cavernous malformations (ECMs) arising from cranial nerves (CNs) are rare. Complete "en bloc" lesion resection and hemosiderin-stained tissue preservation remain the standard treatment, while a different strategy may be needed when the lesion is highly calcified . We report the 3rd calcified ECM-CN and review the clinical features and surgical strategy for this rare condition considering previous literature.

Mixed Signal Intensity on Preoperative T1 MRI Might be Associated with Delayed Postoperative Hemorrhage in Patients with Intracranial Epidermoid Cyst.

Objective: Delayed postoperative hemorrhage (DPOH) was a severe postoperative complication after intracranial epidermoid cyst (EC) surgery. This study was designed to investigate possible clinical data and image features related to DPOH in patients with EC.

Methods: We retrospectively investigated 186 cases of EC, and 8 cases presented an appearance of DPOH.

Intracranial clear cell meningioma: Clinical study with long-term follow-up in 24 patients.

Objective: Clear cell meningioma (CCM) is a rare disease, and controversy about treatment and prognosis of CCMs still exists. We aimed to clarify the natural history, radiological features, histological characteristics, management and prognosis of intracranial CCMs.

Patients And Methods: We performed a retrospective study of 24 patients with intracranial CCM who were treated at West China Hospital from January 2006 to January 2018.
