Seizure in isolated brain cryptococcoma: Case report and review of the literature

Laura Brunasso, Roberta Costanzo, Antonio Cascio, Ada Florena, Gianvincenzo Sparacia, Domenico Gerardo Iacopino, Giovanni Grasso

Date of publication: 14-Apr-2021

Background: Central nervous system (CNS) cryptococcosis is an invasive fungal infection predominantly seen among immunosuppressed patients causing meningitis or meningoencephalitis. Rarely, cryptococcosis can affect immunologically competent hosts with the formation of localized CNS granulomatous reaction, known as cryptococcoma. Common symptoms of CNS cryptococcoma are headaches, consciousness or mental changes, focal deficits, and cranial nerve dysfunction. Rarely, seizures are the only presenting symptom.

Cervical intradural intramedullary collision tumor of schwannoma and hemangioblastoma origin

Rohin Singh, Maziyar Kalani

Date of publication: 14-Apr-2021

Background: Primary spinal tumors are rare benign lesions that represent around 2–4% of all central nervous system neoplasms.[1,2] Intradural intramedullary tumors are predominately glial in origin and are most commonly astrocytomas or ependymomas. Intradural extramedullary tumors, on the other hand, are usually neurofibromas, schwannomas, or meningiomas.[2] Here, we report the case of an intradural intramedullary collision tumor of schwannoma-hemangioblastoma origin.

Bullet retrieval from the cauda equina after penetrating spinal injury: A case report and review of the literature

Disep I. Ojukwu, Timothy Beutler, Carlos R. Goulart, Michael Galgano

Date of publication: 14-Apr-2021

Background: When gunshot injuries occur to the spine, bullet fragments may be retained within the spinal canal. Indications for bullet removal include incomplete spinal cord injury, progressive loss of neurologic function including injury to the cauda equina, and dural leaks with impending risk of meningitis.

Recurrent symptomatic vertebral hemangioma in pregnancy managed with decompression and vertebroplasty

Rudra Mangesh Prabhu, Tushar N. Rathod

Date of publication: 08-Apr-2021

Background: Vertebral hemangioma is a benign vascular tumor of the spine that occurs in the endothelial lining of blood vessels. The majority of these lesions are detected incidentally on routine magnetic resonance imaging scans. Rarely, lesions can increase in size and result in neurological deterioration.

Extracranial vertebral artery to middle cerebral artery bypass in therapeutic internal carotid artery occlusion for epipharyngeal carcinoma: A technical case report

Nakao Ota, Johan Carlos Valenzuela, Daiki Chida, Rokuya Tanikawa

Date of publication: 08-Apr-2021

Background: Vertebral artery (VA) to middle cerebral artery (MCA) bypass is a rarely selected technique because a complex expanded dissection is required, and often, a better donor artery than VA exists. A good indication for VA-MCA bypass is the treatment of head-and-neck malignancies with the sacrifice of the internal carotid artery (ICA) or for carotid artery rupture.

Occipitofrontal switch for correction of anterior plagiocephaly planned through virtual mock surgery

Debarati Chattopadhyay, Madhubari Vathulya, Praveen Jayaprakash, Akshay Kapoor, Vaishali Verma, Rajnish Arora

Date of publication: 08-Apr-2021

Background: Unilateral coronal synostosis causing anterior plagiocephaly can result in restricted brain development and severe facial deformities. Various surgical procedures have been described for the correction of this deformity. Cranial vault remodeling, however, is associated with several complications. Occipitofrontal switching is a novel technique which utilizes a part of the contralateral occipital bone to reconstruct the frontal area. This is the first such case reported from India and first report where virtual mock surgery has been utilized for precision and improving outcome in this elegant procedure.

Coil embolization of subarachnoid hemorrhage with ruptured persistent primitive olfactory artery aneurysm

Tetsu Yamaki, Rei Kondo, Kenshi Sano, Hiroshi Honma, Atsushi Kuge, Shinjiro Saito, Yukihiko Sonoda

Date of publication: 08-Apr-2021

Background: Persistent primitive olfactory artery (PPOA) is a rare anomaly of the anterior cerebral artery. We experienced a rare case of subarachnoid hemorrhage caused by a ruptured saccular aneurysm of PPOA.

Comparatıve assessment of thermal ınjury ınduced by bıpolar electrocautery systems ın a porcıne model

Anil K. Roy, Nefize Turan, Pasang Wangmo, Louis Nkrumah, Stewart G. Neill, Gustavo Pradilla

Date of publication: 08-Apr-2021

Background: Bipolar electrocautery systems used during neurosurgical procedures have been shown to induce thermal injury to surrounding tissue. The goal of this study was to compare the thermal injury induced by two different systems commonly used in neurosurgical procedures (Silverglide by Stryker Corporation and SpetzlerMalis by Codman Neuro), with that of a newly introduced device (TRIOwand by NICO Corporation).

Clinical outcome of intradural extramedullary spinal cord tumors: A single-center retrospective analytical study

Pratik Patel, Dhanish Mehendiratta, Vivek Bhambhu, Samir Dalvie

Date of publication: 08-Apr-2021

Background: Intradural extramedullary spinal cord tumors (IESCT) account for approximately two-thirds of largely benign intraspinal neoplasms. They occasionally present with acute neurological deterioration warranting emergent surgical intervention.

Outcomes of infratentorial cranial surgery for tumor resection in older patients: An analysis of the National Surgical Quality Improvement Program

Krissia M. Rivera Perla, Nathan J. Pertsch, Owen P. Leary, Catherine M. Garcia, Oliver Y. Tang, Steven A. Toms, Robert J. Weil

Date of publication: 08-Apr-2021

Background: Poorer outcomes for infratentorial tumor resection have been reported. There is a lack of large multicenter analyses describing infratentorial surgery outcomes in older patients. We characterized outcomes in patients aged ≥65 years undergoing infratentorial cranial surgery.
