Computed tomography (CT) is widely used for the diagnosis and surgical treatment of spinal pathologies, particularly for pedicle screw placement. However, CT's limitations, notably radiation exposure, necessitate the development of alternative imaging techniques. Synthetic CT (sCT), which generates CT-like images from existing magnetic resonance imaging (MRI) scans, offers a promising alternative to reduce radiation exposure.

Background: Myelomeningocele and sagittal craniosynostosis are 2 neurosurgical pathologies with complications such as increased intracranial pressure (ICP) and hydrocephalus. While the 2 defects commonly occur independently, their simultaneous occurrence is exceptionally rare.

Observations: The authors report the case of a newborn male diagnosed with a simultaneous myelomeningocele and sagittal craniosynostosis.

Cerebral amyloid angiopathy: one single entity?

Curr Opin Neurol

February 2025

Department of Neurology, Leiden University Medical Center, Leiden, The Netherlands.

Purpose Of Review: Cerebral amyloid angiopathy (CAA) is a common brain disorder among the elderly and individuals with Alzheimer's disease, where accumulation of amyloid-ß can lead to intracerebral hemorrhage and dementia. This review discusses recent developments in understanding the pathophysiology and phenotypes of CAA.

Recent Findings: CAA has a long preclinical phase starting decades before symptoms emerge.

In recent years, it has been increasingly recognized that tumor growth relies not only on support from the surrounding microenvironment but also on the tumors capacity to adapt to - and actively manipulate - its niche. While targeting angiogenesis and modulating the local immune environment have been explored as therapeutic approaches, these strategies have yet to yield effective treatments for brain tumors and remain under refinement. More recently, the nervous system itself has been explored as a critical environmental support for cancer, with extensive neuro-tumoral interactions observed both intracranially and in extracranial sites containing neural components.

Objective: The surgical management of craniosynostosis varies without consensus on technique or standard outcomes reporting. The authors of this study aimed to investigate current surgical management of craniosynostosis in the United States.

Methods: Two hundred seventy-five surgeons actively treating craniosynostosis in the United States were surveyed.
