A case report of surgical management of hemangiopericytoma at the foramen magnum

Nobuhiko Arai, Satoshi Takahashi, Hatano Mami, Yukina Tokuda, Kazunari Yoshida

Date of publication: 18-Jul-2017

Background:Hemangiopericytoma (HPC) is a highly vascularized mesenchymal tumor known for its high rates of recurrence and metastasis. The extent of tumor removal is known to be the most trustful prognostic factor. Skull base HPCs are challenging to treat because of the difficulty of the surgical approach and proximity to vital vascular and neuronal structures. We successfully treated a case of HPC at the ventral foramen magnum through surgical gross tumor removal via a far-lateral transcondylar approach.

Spinal thoracic extradural angiolipoma manifesting as acute onset of paraparesis: Case report and review of literature

Franz Jooji Onishi, Flavio Augusto Sekeff Salem, Diogo Luis de Melo Lins, Rafi Felicio Bauab Dauar, João Norberto Stavale

Date of publication: 18-Jul-2017

Background:Angiolipomas are benign tumors most commonly found in the thoracic spine. They are composed of mature adipocytes and abnormal vascular elements that usually present with a slowly progressive course of neurological deterioration.

DRAGON score predicts functional outcomes in acute ischemic stroke patients receiving both intravenous tissue plasminogen activator and endovascular therapy

Arthur Wang, Noorie Pednekar, Rachel Lehrer, Akira Todo, Ramandeep Sahni, Stephen Marks, Michael F. Stiefel

Date of publication: 18-Jul-2017

Background:The DRAGON score, which includes clinical and computed tomographic (CT) scan parameters, predicts functional outcomes in ischemic stroke patients treated with intravenous tissue plasminogen activator (IV tPA). We assessed the utility of the DRAGON score in predicting functional outcome in stroke patients receiving both IV tPA and endovascular therapy.

Modified extradural temporopolar approach with suction decompression for clipping of large paraclinoid aneurysm: Technical note

Naoki Otani, Terushige Toyooka, Kojiro Wada, Kentaro Mori

Date of publication: 18-Jul-2017

Background:Surgical clipping of complicated large paraclinoid aneurysms are still challenging because strong adhesion of aneurysm itself may hinder the dissection of the perforators and the surrounding anatomical structures from the aneurysm dome.

Cervicothoracic cutaneomeningospinal angiomatosis in adults (Cobb's syndrome): A case report of acute quadriparesis

Pablo E. Papalini, Francisco R. Papalini

Date of publication: 18-Jul-2017

Background:Cutaneomeningospinal angiomatosis or Cobb syndrome is a rare, not well understood phacomatosis that features metameric cutaneous and spinal arteriovenous malformations (AVMs). The first case was described in Boston in 1915, and since then, few more cases have been reported in the English literature. No case was found to be from Argentina.

Long-term recurrence of dysembryoplastic neuroepithelial tumor: Clinical case report

Daniel A. Tonetti, William J. Ares, R. Mark Richardson, Ronald L. Hamilton, Frank S. Lieberman

Date of publication: 11-Jul-2017

Background:Dysembryoplastic neuroepithelial tumors (DNETs) are rare, benign brain neoplasms that typically arise in children and adolescents and classically present with intractable, partial complex seizures. DNETs are classically associated with a favorable prognosis after complete surgical resection.

Primary decompressive craniectomy is associated with worse neurological outcome in patients with traumatic brain injury requiring acute surgery

Julius Tapper, Markus B. Skrifvars, Riku Kivisaari, Jari Siironen, Rahul Raj

Date of publication: 11-Jul-2017

Background:The role of decompressive craniectomy in treating raised intracranial pressure (ICP) after traumatic brain injuries (TBI) is controversial. The aim of this study was to assess the differences in prognosis of patients initially treated by decompressive craniectomy, craniotomy, or conservatively.

B-cell lymphoma presenting as multiple nerve sheath tumors

Jason Milton, Julie Renner, Victor Awuor

Date of publication: 11-Jul-2017

Background:Diffuse Large B-cell Lymphoma (DLBCL) is the most common form of Non-Hodgkin lymphoma (NHL), accounting for 25-30 percent of cases in the United States.1 Extranodal sites are involved in approximately 40% of cases of DLBCL.

Delayed presentation of spinal foreign body – Case report and review of literature

Franz J. Onishi, Mirto N. Prandini, Sergio Cavalheiro

Date of publication: 11-Jul-2017

Background:Although spinal cord injuries are frequent causes of myelopathy in young patients, stab wounds of the spinal cord rarely occur and are typically maximal symptomatic immediately after the trauma.

Ruptured mycotic aneurysms: Report and outcomes of two surgically managed patients

Aleena Khan, Muhammad Waqas, Waseem M. Nizamani, Muhammad E. Bari

Date of publication: 11-Jul-2017

Background:Mycotic aneurysm is a rare potentially life-threatening complication of infective endocarditis (IE). Little data is available on the management and outcomes of ruptured mycotic aneurysms with large intracerebral hematoma. Few cases have been described on the management of mycotic aneurysm in the presence of life-threatening hematoma and mass effect.
