Volume 145, January 2021, Pages 1-4
The efficacy and safety of endoscopic procedures for slit ventricle syndrome (SVS) have been presented in recent studies. However, inserting a sheath into a target ventricle is essential in the beginning of endoscopic procedures for SVS, and this maneuver is challenging owing to the quite narrow ventricular space. We report a novel flexible endoscopic technique, the water-slide technique, that can effectively guide a sheath into a slit ventricle without the use of other adjunctive devices, such as a neuronavigation system and an ultrasound machine.
Keyhole Superior Interhemispheric Transfalcine Approach for Tuberculum Sellae Meningioma: Technical Nuances and Visual Outcomes

Tuberculum sellae meningiomas are challenging tumors often compressing the optic apparatus and involving the optic canals. Traditional approaches provide wide exposure, but optic canal access can remain difficult. Endonasal approaches offer a less invasive option that allows access to the medial optic canals, but larger tumors can still be challenging along with a higher risk of postoperative spinal fluid leak. We present the use of a keyhole superior interhemispheric approach for tuberculum sellae meningioma resection.

doi : 10.1016/j.wneu.2020.09.005
Volume 145, January 2021, Pages 51-56
Flow diversion with or without coil embolization has become the first-line treatment for large or giant paraclinoid internal carotid artery intracranial aneurysms. Oftentimes, these sizable aneurysms impose anatomical challenges to endovascular treatment through limiting both distal outflow access and maintenance of distal vessel purchase during catheter reduction, which are required for successful stent placement. Various strategies to obtain and maintain distal access within the parent vessel have been described previously; however, new techniques may need to be employed when more standard maneuvers fail.
Atypical Teratoid/Rhabdoid Tumor of the Cerebellum in an Adult: Case Report and Literature Review

Atypical teratoid/rhabdoid tumor (AT/RT) is a rare tumor that is most frequently encountered in the pediatric patient population. AT/RT accounts for approximately 1%?2% of all pediatric central nervous system tumors and roughly 10%?20% of tumors in patients younger than 3 years of age. While AT/RT has been encountered in the adult population, the vast majority of the cases reported occur in the supratentorial space. In the existing literature, only 3 adult cases that arise from the cerebellum have ever been reported.

Subungual melanoma (SUM) is a rare form of melanoma confined to the nailbed and is rarely of the desmoplastic subtype. The often subtle nature of SUM, initially starting as a small dark spot or line in the nailbed, means deeper invasion can occur before a patient seeks clinical evaluation for a large, ulcerated lesion. We report the only known case of perineural spread of SUM of the lower extremity and describe its extensive path of perineural spread from the toe.

Inflammatory demyelinating changes in the absence of malignant cells can sometimes be found on initial biopsies preceding the diagnosis of primary central nervous system lymphoma (PCNSL), resulting in the term “sentinel” lesion. Sentinel lesions have been reported sporadically in literature, resulting in many cases of misdiagnosis and delayed treatment. We aim to address the problem of misdiagnosis in PCNSL presenting as inflammatory demyelinating changes or sentinel lesions on initial biopsies, and to discuss our view of the mechanism underlying this phenomenon.

Aneurysmal subarachnoid hemorrhage (aSAH) is associated with high morbidity and mortality. Among the most common sequelae of aSAH is delayed cerebral ischemia. Hyperdynamic therapy (fluid supplementation and hypertension) is used to increase cerebral perfusion. However, the safety of hyperdynamic therapy in patients with separate unruptured, unsecured intracranial aneurysms is not well-established. Herein, a rare case demonstrating the rapid evolution and rupture of an incidental unsecured aneurysm in the setting of hyperdynamic therapy is presented.

doi : 10.1016/j.wneu.2020.09.136
Volume 145, January 2021, Pages 315-319
Third ventricle cavernous malformations (CMs) associated with ventriculomegaly and obstructive hydrocephalus are quite rare in patients. Preoperative surgical planning can be challenging due to the lesion's non-specific appearance on CT and magnetic resonance imaging that can mimic other intraventricular pathologies, such as a colloid cyst. Management of these lesions can be varied in the setting of obstructive hydrocephalus.

doi : 10.1016/j.wneu.2020.09.108
Volume 145, January 2021, Pages 340-347
A collision tumor is a rare entity consisting of 2 histologically distinct tumor types (benign or malignant) in the same anatomic location. This can occur from a tumor-to-tumor metastasis or as a result of 2 adjacent intracranial tumors colliding and growing together. To our knowledge, this is the first reported case of collision tumor with confirmed meningioma and uterine adenocarcinoma. Multiple mechanisms have been proposed for the facilitative growth of collision tumors, including local epigenetic signaling. Clinically, it is important to consider collision tumors in the differential diagnosis of a rapidly growing intracranial lesion in the setting of systemic cancer to provide optimal surgical and postoperative management.

Primary central nervous system sarcomas are rare primitive mesenchymal non-meningothelial tumors. Malignant peripheral nerve sheath tumor accounts for 5% of sarcomas, with an incidence of approximately 0.001% and a recognized association with neurofibromatosis type 1. Its intracranial subtype, the so-called malignant intracerebral nerve sheath tumor (MINST), is even more infrequent. Current knowledge about its clinical presentation and best therapeutic management is poor because of the limited number of cases reported in literature. Commonly, intratumoral hemorrhage occurs at the time of diagnosis and, notably, most patients had intracranial hemorrhage prior to definitive diagnosis.

The vertebral arteries are branches of the subclavian arteries supply blood to the posterior part of the encephalon, forming vertebrobasilar circulation. Disorders of vertebrobasilar circulation have significant clinical implications. Symptoms of these disorders include dizziness, vomiting, collapse, vision and cerebellar disorders. The vertebral artery usually ascends in the transverse foramina of the cervical vertebrae to reach the posterior cranial cavity by entering the magnum foramen. Although most often the vertebral artery enters the C6 transverse process, anatomic variation may occur.

Intramedullary spinal cord metastasis (ISCM) account for a minority of all spinal cord tumors. Rarely, symptoms from ISCM may be the initial presentation of an unknown primary carcinoma. Intramedullary metastasis from a second malignancy or from an unknown neuroendocrine malignancy is extremely rare and has never been reported in the literature. Because of the rarity of these tumors and the low volume of cases, well-defined treatment guidelines do not exist for the management of ISCM. Here we present a rare and one of the first reports of an intramedullary metastatic neuroendocrine tumor.
