BACKGROUND: Immune checkpoint inhibitors (ICIs) are a promising class of anticancer drugs associated with immune-related adverse events (IRAEs). In registration studies of selected cancer populations, neurologic IRAEs were rare. Post-marketing experience describing their prevalence in clinical practice continues to be reported. METHODS: A retrospective cohort of patients treated at our institution with ICIs from 2005 to 2017 was identified. Patients with new neurologic ICD codes documented during or after ICI treatment were enrolled...

OBJECTIVE Despite the extensive use of the subthalamic nucleus (STN) as a deep brain stimulation (DBS) target, unveiling the extensive functional connectivity of the nucleus, relating its structural connectivity to the stimulation-induced adverse effects, and thus optimizing the STN targeting still remain challenging. Mastering the 3D anatomy of the STN region should be the fundamental goal to achieve ideal surgical results, due to the deep-seated and obscure position of the nucleus, variable shape and relatively small size, oblique orientation, and extensive structural connectivity...

We herein report a patient with Miller Fisher syndrome mimicking Tolosa-Hunt syndrome. A 47-year-old man presented with right orbital pain and diplopia. On a neurological examination, he had right oculomotor nerve palsy and diminished deep tendon reflexes. Brain magnetic resonance imaging failed to show any parenchymal lesions; however, the bilateral oculomotor nerves were gadolinium-enhanced. The presence of a triad of orbital pain, ipsilateral oculomotor nerve palsy, and a rapid response to steroid therapy met the diagnostic criteria for Tolosa-Hunt syndrome...

The development of ptosis as a consequence of pituitary tumor is an exceptionally rare occurrence. Here, we describe the case of sudden-onset unilateral ptosis induced by pituitary macroadenoma. The condition was characterized by false-positive Jolly and neostigmine tests. These findings mimic oculomotor nerve palsy and make the correct diagnostics rather challenging. The case points to the fact that patients with acquired ptosis need detailed neuroophthalmological examination.

The transcavernous approach to the basilar artery, as initially described by Dolenc, is one of the most common and elegant approaches to the region. It affords a generous working and viewing angle, but it can be technically challenging and requires attention to detail at each step. We investigate this approach in this report via a cadaveric prosection with a focus on the value of each of the component steps in improving surgical view and exposure. The transcavernous approach steps are divided into extradural stages: orbitozygomatic osteotomy (a modern adjunct to Dolenc's original description), drilling of the lesser sphenoid wing, and anterior clinoidectomy; and intradural stages: wide splitting of the Sylvian fissure, unroofing of the oculomotor and trochlear nerves, and posterior clinoidectomy...

The surgical procedures directed to the orbit are invariably reported to be one of the most challenging procedures of the neurosurgery and it is very important to take measures to protect the ocular nerves. Many researchers have tried to identify safe approaches or safe regions in the orbit but the suggestions and results vary among published studies. The ocular motor nerves are under risk of injury during various approaches to the orbit. Simple but careful attention to potential variations in the origin and anatomical course of the ocular nerves and their relationships to the orbit may help to define "safe zones" during various approaches, thus help to enhance clinical outcomes...

OBJECTIVE Pituitary adenomas may extend into the parapeduncular space by invading through the roof of the cavernous sinus. Currently, a transcranial approach is the preferred choice, with or without the combination of an endonasal approach. In this paper the authors present a novel surgical approach that takes advantage of the natural corridor provided by the tumor to further open the oculomotor triangle and resect tumor extension into the parapeduncular space. METHODS Six injected specimens were used to demonstrate in detail the surgical anatomy related to the approach...

Hyaluronic acid (HA) is the most popular agent today for intradermal injections to improve wrinkles and other cosmetic defects. Ischemic necrosis due to injection of HA is one of the serious complications. Because there are many vascular branches around the nose, caution and care should be given during facial filler injection. Although the incidence is rare, blindness and permanent visual loss may occur. We describe a 29-year-old woman presented with painful erythematous swelling with violaceous patch on right periocular area and glabella after HA filler injection...

INTRODUCTION: Meningiomas with orbital extension are the most frequent benign orbital tumors. The few studies available on the postoperative complications of their excision focus on the postoperative evolution of proptosis, visual acuity and visual field deficits. The goal of our study was to highlight the oculoplastic complications secondary to their excision. MATERIAL AND METHOD: We identified all cases of meningiomas with orbital extension undergoing excision either neurosurgically or via an orbital approach in the ophthalmology and neurosurgery departments of Pasteur university medical center in Nice between February 2011 and January 2017...

BACKGROUND: Temporal lobe resection (TLR) including amygdalohippocampectomy (AHE) is the most frequent performed procedure in epilepsy surgery. Owing to the close anatomic relationship of the mesial temporal structures and the midbrain and choroidal fissure, the incidence of severe complications, such as postoperative stroke, is as high as 2.5%. METHODS: We developed a modification of the classical technique for AHE that involves entering the choroidal fissure early via the anterior part of the frontomesial temporal horn cleft to identify the crus cerebri, posterior cerebri artery, and oculomotor nerve...

BACKGROUND: Acquired brain injury can cause eye movement disorders which may include: strabismus, gaze deficits and nystagmus, causing visual symptoms of double, blurred or 'juddery' vision and reading difficulties. A wide range of interventions exist that have potential to alleviate or ameliorate these symptoms. There is a need to evaluate the effectiveness of these interventions and the timing of their implementation. OBJECTIVES: We aimed to assess the effectiveness of any intervention and determine the effect of timing of intervention in the treatment of strabismus, gaze deficits and nystagmus due to acquired brain injury...

BACKGROUND AND IMPORTANCE: Cavernous malformations (CMs) are vascular abnormalities with a hemorrhage risk of 0.2% to 5% per year, according to their location. Brainstem CMs seem to have a greater hemorrhagic risk and represent a neurosurgical challenge. We report here the first transsylvian transuncal (TS-TU) approach for an anteromedial mesencephalic CM resection. CLINICAL PRESENTATION: A 29-yr-old female suddenly presented a left hemiparesis and central facial paresis with a diplopia in the upward gaze...

This is a case of an extensive tuberculum sella meningioma involving the circle of Willis down to the basilar artery that presented with bilateral visual loss worse on the right than left side. A one-piece right orbitopterional approach along the worse eye was used to gain access to the three cranial fossae. The orbitotomy facilitates access to the midline structures and contralateral base of the tumor with minimal brain retraction. Tumor resection is initiated by first identifying the tumor capsule, followed by piecemeal debulking via ultrasonic aspiration...
