Neurological Functional Surgery in Mexico: From Pre-Columbian Cranial Surgery to Functional Neurosurgery in the 21st Century.
From the predominance of the pre-Columbian cultures to the present, an interest has existed in Mexico in brain structure and function, in both normal and pathological conditions. This interest has resulted in both medical and surgical attempts to treat some neurological conditions. ⋯ At present, functional neurosurgery in Mexico constitutes, similar to that in other countries, a recognized surgical subspecialty that provides valuable information to treat brain dysfunctions such as movement disorders, pain, epilepsy, and other conditions. In the present report, we have briefly described the main historical aspects of the emergence and development of functional neurosurgery in Mexico.

Exophytic primary spinal intramedullary glioblastoma: A case report and critical review of literature.
Primary intramedullary spinal cord (IMSC) glioblastoma (GBM) is an extremely rare entity; we report the first case of primary IMSC GBM presenting with exophytic involvement. The prognosis of glioblastoma remains poor due to the aggressive nature of the disease and lack of effective treatment. ⋯ Although MRI is of indisputable importance in the diagnosis of spinal cord lesions, immunohistochemical and histopathologic studies are often required to establish a definitive diagnosis. It remains unclear how the unusual involvement of exophytic growth will affect the prognosis of primary IMSC GBM.

The Incremental Value of Magnetic Resonance Neurography for the Neurosurgeon: Review of the Literature.
Magnetic resonance neurography (MRN) is a newer imaging technique that is increasingly used for detailed visualization of peripheral nerves not reliably achieved with conventional imaging modalities. Although MRN has been previously characterized in the literature, few studies have assessed its utility to neurosurgery, where there is potentially substantial impact particularly with preoperative assessment. In this article, we performed a retrospective review of cases in which MRN was used for clinical evaluation and surgical decision making. ⋯ MRN is an underused resource with great potential value in the diagnoses, surgical planning, and postoperative assessment of various neurosurgical conditions. These present incremental utility to the neurosurgeon as well as socioeconomic benefit in the detection of potentially surgically treatable lesions.

Correlation Studies and Literature Review of Medullary Artery Occlusion after Intracranial Vertebral Artery Stenting.
Stenosis of the target intracranial vertebral artery is one of the major causes of posterior circulation ischemic stroke. The objective of this paper is to explore methods for reducing the occurrence of medullary artery occlusion after intracranial vertebral artery stenting. ⋯ Perforating artery occlusion after intracranial vertebral artery stenting can be prevented by strict assessment and preparation before surgery, correct choices of saccule and stent during operation, and other measures. However, large sample data are needed for verification.

Intracranial Actinomycosis Presenting As A Parenchymal Mass Lesion: A Case Report And Review Of Literature.
Intracranial actinomycosis is a rare bacterial infection with no characteristic clinical or radiologic diagnostic features. The usual presentation is similar to pyogenic brain abscess or osteomyelitis with or without pachymeningitis. Intracranial actinomycosis rarely manifests as a parenchymal mass lesion. A high index of suspicion is warranted in a patient with immunosuppression or predisposing factors, such as dental procedure, sinusitis, cardiac septal defect, craniofacial trauma, cranial surgery, lung infection, or abdominopelvic infection. ⋯ Intracranial actinomycosis manifesting as a parenchymal mass lesion is extremely rare compared with abscess and pachymeningitis. Histopathologic examination remains the mainstay of definitive diagnosis, as culture may be negative in significant number of cases. Aggressive surgical excision with prolonged antibiotic therapy enhances the chances of a good functional outcome.
