The Latin American Federation of Neurosurgical Societies (FLANC) is a nongovernmental, nonprofit civil association, founded to promote neurosurgery in the Latin American countries. The American College of Surgeons and American Association of Neurological Surgeons has recommended a ratio of 1 neurosurgeon/100,000 inhabitants. We aimed to estimate the neurosurgical workforce of the FLANC in 2020. ⋯ The FLANC has significant disparities in neurosurgical workforce ratios among the member countries. Central American countries probably have the greatest needs. Gender equity should also be improved among the training institutions. We encourage readers to develop future research into the local geographical distribution of neurosurgeons among the countries to better understand their needs and barriers to providing high-quality standards of care.

Aneurysms originating from the distal portion of the lenticulostriate artery (LSA) are uncommon. Distal medial LSA (MLSA) aneurysms are particularly uncommon when compared with distal lateral LSA aneurysms, and their clinical features are unclear. Here, we present 2 patients with aneurysms of the distal MLSA who exhibited hemorrhages of the caudate nucleus and intraventricular region (intraventricular hemorrhage [IVH]). ⋯ We should consider the possibility of a ruptured distal MLSA aneurysm when diagnosing a patient with IVH-with or without a caudate nucleus hematoma. Repeated imaging evaluations may be necessary to find the lesion.

Choroid Plexus Cyst of the Fourth Ventricle associated with Intermittent Obstructive Hydrocephalus: Case Report.
Choroid plexus cysts (CPCs) are a type of neuroepithelial cysts, benign lesions located more frequently in the supratentorial compartment. Symptomatic CPCs in the posterior fossa are extremely rare and can be associated with obstructive hydrocephalus. ⋯ Fourth ventricle symptomatic CPCs are extremely rare lesions, especially in the elderly. Their presence must be carefully evaluated as a possible rare cause of intermittent obstructive hydrocephalus. Even though cyst fenestration with restoration of the cerebrospinal fluid pathway represents the best treatment in the majority of cases, a more aggressive resection is sometimes necessary.

In the present study, we updated our previously reported case series of patients who had undergone decompressive craniectomy for malignant middle cerebral artery infarction (mMCAI) (2005-2020). To the best of our knowledge, the present case series constitutes the largest reported series from a UK neurosurgical unit of decompressive craniectomy for mMCAI. ⋯ The findings from the present update have confirmed that local practice has remained consistent with current evidence. However, patient selection might be optimized if diffusion-weighted magnetic resonance imaging and computed tomography perfusion were used at the original middle cerebral artery infarct admission.

A detailed understanding of the anatomy of Sylvian veins preoperatively is needed for venous-preserving Sylvian dissection. Better visualization of the venous architecture will facilitate surgical strategies for Sylvian dissection. This study evaluated and compared the image quality of the Sylvian veins and their tributaries using high-resolution cone-beam computed tomography angiography (CBCT-A) and three-dimensional computed tomography angiography (3D-CTA). ⋯ CBCT-A was superior to 3D-CTA for visualizing the Sylvian veins and their tributaries. CBCT-A will provide important information on the anatomy of the Sylvian veins preoperatively.
