Article Type: Case Report | First Published: November 04, 2019
Carotid - cavernous fistulas (CCF) are spontaneous or acquired communications between the internal carotid artery (ICA) and the cavernous sinus, which can be classified as direct or indirect. Direct fistulas between the internal carotid artery and the cavernous sinus can occur due to trauma, ruptures of intracavernous carotid artery aneurysms, collagen deficiency syndromes, stratification of arteries, fibromuscular dysplasia, and direct surgical trauma. Symptoms caused by CCF are associated with...
A Review of Radiographic Imaging Findings of Ependymal Tumors

Article Type: Review Article | First Published: October 24, 2019
Ependymomas are glial tumors that typically arise from the lining of the ventricles or the central canal of the spinal cord. The most common site of occurrence is within the posterior fossa. Subtypes of ependymomas include anaplastic ependymoma, myxopapillary ependymoma, and subependymoma. Its characteristic imaging features include findings of a heterogeneous mass with necrosis, calcifications, cystic changes, and hemorrhage. Treatment options includes partial resection with or without irradiat...

Liponeurocytoma is a very rare tumor of the nervous system, with only 63 reported cases, mainly in the cerebellum and ventricular system. The key-points for the diagnosis are the histological findings of neurocytic cells with lipidic accumulation, with positivity for S-100 and synaptophysin and negativity for IDH-1, and the MR finding of hyperintensity areas on T1Wi corresponding to fatty tissue within the tumor. This article reports a case of cerebellar liponeurocytoma presenting with acute ict...
Pharyngeal Perforation after Anterior Cervical Fusion Surgery

Article Type: Case Report | First Published: October 07, 2019
Pharyngeal perforation is a serious complication of anterior cervical fusion surgery. If it is not diagnosed in the early period and the treatment is delayed, catastrophic consequences may occur which may cause death such as septicemia, mediastinitis, pneumonia and meningitis. We shared the presentation of our two cases. In the first case, pharyngeal perforation and spontaneous extrusion of the C2-C3 fixation device occurred after eight years from surgery. The fixation device removed and the pha...
Lymphomatoid Granulomatosis of the Central Nervous System, Successfully Treated with Corticosteroid Alone: A Case Report and Review of the Literature
Alexandra Benouaich-Amiel, Shlomit Yust-Katz, Suzana Fichman and Tali Siegal
Article Type: Case Report | First Published: December 20, 2018
Lymphomatoid granulomatosis (LYG) is a rare, Epstein barr virus (EBV) associated, angiocentric B cell proliferation, which usually involves the lung but may also involve, more rarely, the central nervous system. Its malignant potential is uncertain, and seems to be linked to the number of EBV positive B cells. We report the case of a 32-years-old patient, with an antecedent of LYG grade 2, involving lung, who presented with a brain mass lesion one year later, which appears to be a grade 1 LYG wi...
Multimodal MRI of Extracranial Glioblastoma Dissemination
Alice Venier, Luca Roccatagliata, Alessandro Cianfoni and Emanuele Pravata
Article Type: Case Report | First Published: December 15, 2018
Glioblastoma scalp dissemination is uncommon. Infiltration may occur through the craniotomy, suggesting diffusion from the surgical site as the most likely mechanism. At Magnetic Resonance Imaging (MRI), features of the metastatic tissue resemble those of the primary tumor. We show multimodal MRI appearance of a glioblastoma disseminating to the scalp. The patient presented with a stiff, non-tender palpable mass within the extracranial soft tissues, five months after surgery. Distinctive finding...
Giant Prolactinoma and Concomitant Internal Carotid Artery Pseudo-Aneurysm: All Stages of the Decision-Making Process

Article Type: Case Report | First Published: November 19, 2018
We report a case of right internal carotid artery pseudo-aneurysm, arising in the aspects of a giant macroadenoma in a 57-years-old man, presented with right severe temporal orbital headache and vomiting. Computed tomography scan (CT) revealed a destructive skull base mass extended from sellar region to clivus. Pre and post-gadolinium brain magnetic resonance (MRI) confirmed the lesion, characterized by an encasement of optic nerves and carotid siphons bilaterally, with a pseudo-aneurysm of cave...
Surgical Treatment of Mesial Temporal Lobe Epilepsy: Selective Amygdalohippocampectomy Using Niemeyer's Approach
Adriana Rodrigues Liborio dos Santos, Gabriel Mufarrej, Priscila Oliveira da Conceicao, Paulo Luiz da Costa Cruz, Daniel Dutra Cavalcanti, Leila Chimelli and Paulo Niemeyer Filho
Article Type: Original Article | First Published: November 19, 2018
Selective Amygdalohippocampectomy (SAH) is a widespread technique for Mesial Temporal Lobe Epilepsy (MTLE) treatment. Dr. Niemeyer was the first to describe SAH using transventricular approach technique in 1958. In 2018, we celebrate 60 years of the original description of Niemeyer's approach. This study reviews the approach in light of currently technology and shows the results achieved with patients submitted to SAH following Niemeyer's approach at Instituto Estadual do Cérebro Paulo Niemeyer...
Frazier Suction Cannula Fluid Control Technical Note
Manuel Dujovny, Channan Kositzke, Pablo Sosa and Fabian Cremaschi
Article Type: Research Article | First Published: November 10, 2018
Suction capability in neurosurgery is a critical tool utilized to clear the field and improve visualization of anatomical structures. It is also used for fragmentation and debulking of pathological tumor masses. Prior to the Frazier cannula, there was no orifice bent pressure relief valve associated with suction; this tool provides independent dual suction force. The Frazier cannula has the capability to reach absolute suction or zero suction instantaneously. In this article, we introduce a new ...
What Should Guide Decision-Making Process in Urgency? A Curious Case of Right Acute Hemiparesis

Article Type: Case Report | First Published: October 31, 2018
As physicians and neurosurgeons, our daily practice in Emergency Departments sometimes calls us to manage patients and to take decisions in sub-optimal conditions, maybe with partial anamnesis, incomplete neurological examinations or with lacks in routine radiological and laboratory exams. Such eventuality, although it may sometimes lead to misdiagnose and to confound some pathological conditions, fortunately is not always linked to bad repercussions for patients. This is especially true when de...

Article Type: Case Report | First Published: June 15, 2018
A giant cell granuloma (GCG) rarely occurs in the skull bones. Although it has destructive character, the GCG is used as the synonym of giant cell reparative granuloma (GCRG) in the literature. Differentiation from other osteolytic lesions quite difficult. The first case of GCG in the temporal bone was reported by Hirschl and Katz in 1974. Even though the GCG is not a true neoplasm, the locally aggressive behavior of this tumor necessitates surgical excision whenever possible....
