360-surgery for a giant cervical chordoma with involvement of the right vertebral artery.

Background: Chordomas are malignant tumors that arise from the remnants of the notochord. Complete radical resection with postoperative radiation therapy is currently considered the gold standard. Here, we performed a 360-staged approach to manage a C3-C4 chordoma that involved the right vertebral artery.

Case of anterolateral migration of herniated cervical disc fragment mimicking a spinal meningioma.

Background: Before the introduction of high-resolution MR, few disc fragments were misdiagnosed as meningiomas.

Case Description: A 63-year-old female presented with a 6-month history of mild to moderate pain in the left arm, weakness 4/5 in the left arm C5-C6 distribution, and a loss of the left biceps reflex response. Although the MR study was read as showing a C5-C6 level probable spinal meningioma, this proved to be a sequestrated disc fragment at surgery.

Histopathological Correlation (World Health Organization Classification) of Meningiomas and Their Anatomical Localization: A Multicenter Epidemiological Study in Mexico.

Objective: To determine the epidemiology of the localization and histological type of meningiomas in the Mexican population and the distribution of the different histological patterns and their relationship to tumor localization and patient demographics.

Methods: A retrospective analysis was performed in 5 hospitals in Mexico from 2009 to 2019. For qualitative variables, mean values were compared using Pearson χ test for the correlation between location and histological pattern as well as the clinical presentation and the patient's sex.

Spinal drop of atypical choroid plexus papilloma in an adult patient: A case report and literature review.

Background: Choroid plexus papillomas (CPPs) are benign extra-axial tumors that originate from the choroid plexus; these tumors rarely have metastases, being at the spinal level the location with few reported cases.

Case Description: We report the case of a 48-year-old man with a history of atypical fourth ventricular CPP and gross total resection (GTR) in 2008. In 2015, he presented with radicular pain, decreased strength, and paresthesia in the left leg.
