Meningiomas are the second most common neoplasm in the cerebellopontine angle (CPA), and are challenging lesions to treat surgically. With significant refinements in surgical techniques, operative morbidity, and mortality have been substantially reduced. Total or near-total surgical resection can be accomplished in the majority of cases via appropriately selected approaches, and with acceptable morbidity. In this video, we present a 51-year-old woman, who had a 2-year history of vertigo with symptoms that progressed over time...

Postoperative endophthalmitis is a severe complication which may result in loss of vision. Intracameral antibiotics have been shown to reduce the risk of this complication and are extensively used worldwide, with vancomycin, cefuroxime and moxifloxacin most commonly used. Choices in Australia are currently limited to vancomycin and cefazolin, since cefuroxime and moxifloxacin are not available. Vancomycin has been safely and effectively used in our department for more than two decades. Recent publications have risen concerns regarding the association of haemorrhagic occlusive retinal vasculitis a potentially blinding complication with intracameral vancomycin...

BACKGROUND: Symptoms that mimic pituitary apoplexy may be encountered with other neoplastic or infectious lesions. CASE DESCRIPTION: This 38-year-old man presented with severe sudden-onset headache and relapsing and remitting vision loss. Radiographic imaging studies demonstrated radiographic features of a hyperdense, hemorrhagic mass in the sellar region. MRI revealed a 4-cm mass abutting the optic chiasm and compressing the pituitary. After 4-week follow-up surveillance MRI demonstrated near-complete resolution of the previously identified planum sphenoidale and suprasellar mass, the patient re-presented 13 months later with recurrent symptoms...

OBJECTIVE: Although meningiomas frequently involve the optic nerve, primary optic nerve sheath meningiomas (ONSMs) are rare, accounting for only 1% of all meningiomas. Given the high risk of vision loss with these tumors, surgical intervention is seldom considered, and radiation or observation is commonly applied. Here, the authors describe the visual outcomes for a series of patients who were treated with surgery aiming at maximal tumor resection and highlight their prognostic factors...

OBJECTIVE: The unexpected intraoperative intraventricular hemorrhage is a rare but feared and life-threatening complication in neuroendoscopic procedures because of loss of endoscopic vision. The authors present their experience with the so-called "dry field technique" (DFT) for the management of intraventricular hemorrhages during purely endoscopic procedures. This technique requires the aspiration of the entire intraventricular CSF to achieve clear visualization of the bleeding source...
