Early and late images of 123I-iomazenil (123I-IMZ) single-photon emission computed tomography (SPECT) are considered to show cerebral blood flow and neuronal activity, respectively, and this modality may demonstrate temporal dysfunction of the frontal lobes in obstructive hydrocephalus. In this report, we examined 123I-IMZ SPECT in a patient with chronic obstructive hydrocephalus owing to compression of the aqueduct by a partially thrombosed aneurysm of the left posterior cerebral artery for the first time. ⋯ The findings in the present case indicate that 123I-IMZ SPECT can detect reversible cerebral blood flow reduction and neuronal viability in the frontal lobes, which may affect the clinical manifestation of obstructive hydrocephalus.

Cerebral hyperperfusion syndrome, which carries a potential risk of intracranial hemorrhage, is a rare and overlooked condition in the setting of subarachnoid hemorrhage (SAH). ⋯ This is the first report to describe postischemic cerebral hyperperfusion syndrome after symptomatic vasospasm detected using sequential single-photon emission computed tomography during the acute stage of SAH. Early diagnosis of this rare phenomenon is crucial given the necessity to lower blood pressure for preventing hemorrhagic complications, which is contrary to the usual management of patients with vasospasm.

Lumbar puncture is a common procedure that can be safely performed in most patients. Certain populations may have increased risk for complications following lumbar puncture, but the significance of basilar invagination is often underappreciated. ⋯ Basilar invagination is a risk factor for devastating neurologic complications following lumbar puncture. Awareness of this complication and prompt recognition of its occurrence may prevent future morbidity of lumbar puncture in patients with basilar invagination.

Review
Review of the Highlights from the First Annual Global Neurosurgery 2019: A Practical Symposium.
This paper provides a detailed report of Global Neurosurgery 2019: A Practical Symposium held January 18-19, 2019, at Weill Cornell Medical College, New York, New York, USA. The meeting convened an international faculty and audience, leaders in the world of global neurosurgery (GNS), and junior faculty and residents beginning their contribution to the field. ⋯ The goal of the symposium was to present the state of the union of GNS initiatives worldwide, to use this forum as a means to centralize resources and converge parallel efforts, and to identify the largest areas of need and successful means of advancing training and care in these areas. The meeting also served as a conduit for the presentation of funding and training opportunities for junior faculty and trainees looking for avenues to gain support and mentorship in pursuing academic and clinical endeavors globally.

Case Reports
Fully endoscopic transforaminal-transchoroidal approach for tectal area tumors removal.
The surgical approaches to lesions located in the tectal area have remained controversial. The essential functions in the surrounding areas and the difficulties in obtaining a good surgical view during tumor removal have made these procedures risky and challenging. Endoscopic transforaminal approaches have been previously described for biopsy and intraventricular tumor removal. However, the endoscopic transforaminal-transchoroidal gross resection technique for such cases has barely been described. ⋯ In our experience, a fully endoscopic transforaminal-transchoroidal approach was a suitable treatment for this complex pathological entity. Opening of the choroidal fissure added an extra angle of work and improved the exposure of the upper posterior part of the third ventricle.
