T2-highlighted U-fibres and rapid parenchymal volume loss in AESD: an under-recognised subtype of paediatric acute encephalopathy syndromes
We present three paediatric cases from a tertiary paediatric neurosciences centre in xxxxx with characteristic subcortical signal change, and furthermore, follow up imaging which in all 3 patients demonstrated a varying degree of cerebral atrophy. We recommend that children presenting with prolonged seizures should be considered for MR imaging ideally after 48 hours if clinically stable, and early MR imaging follow-up (at 2-3 months) be performed routinely in patients with AED to assess for presence and degree of parenchymal volume loss for prognostication and to start neuroprotective therapy.

Intraoperative MRI and FLAIR Analysis: Implications for Low-Grade Glioma Surgery
The objective of this study was to report the existence of FLAIR abnormalities on iMRI that may occur on the margin of a brain resection and may lead to misdiagnosis of residual tumor.Methods: We retrospectively analyzed intraoperative MRI (iMRI) in 21 consecutive patients who underwent surgery for a low-grade glioma. Two readers independently reviewed iMRI images to search for the presence of a FLAIR hyperintensity surrounding the surgical cavity. For each patient, they were instructed to characterize FLAIR abnormalities on the margins of the resected area as (1) no FLAIR abnormality; (2) “linear FLAIR hyperintensit...

Posterior fossa tumors in children: Radiological tips & tricks in the age of genomic tumor classification and advance MR technology
The objective is to propose a global method relying on the combined analysis of radiological, clinical and epidemiological criteria, (taking into account the child’s age and the topography of the lesion) in order to improve our histological approach in imaging, helping the management and approach for surgeons in providing information to the patients’ parents. Infratentorial tumors are the most frequent in children, representing mainly medulloblastoma, pilocytic astrocytoma and brainstem glioma. Pre-surgical identification of the tumor type and its aggressiveness could be improved by the combined analysis of key...

Central Nervous System involvement in tuberculosis: an MRI study considering differences between patients with and without Human Immunodeficiency Virus 1 infection
Conclusions Stroke involving the basal ganglia best differentiates CNSTB patients who are HIV+ from those HIV-. This finding was not correlated with meningeal enhancement suggesting that small arteries involvement might precede it. Therefore, we think that HIV+ patients with a new onset of stroke should be evaluated for CNSTB. Follow-up MRI should also be planned since meningeal enhancement might appear in later stages of the disease. (Source: Journal of Neuroradiology)

The PHASES score: to treat or not to treat? Retrospective evaluation of the risk of rupture of intracranial aneurysms in patients with aneurysmal subarachnoid hemorrhage
CONCLUSION: Of our patients 78.7% had less than a 2% 5-year rupture risk based on their PHASES score, highlighting the discrepancy of the rupture risk calculated with the PHASES score when hypothetically applied to this group of patients. In the hypothetical scenario that our patients had unruptured aneurysms, our retrospective analysis shows that the PHASES score may only provide a weak tool for clinicians to use in the decision-making process as to whether or not to treat these aneurysms.

We report an anatomical-based association between conus medullaris pial arteriovenous shunt that drain caudally towards the lumbosacral area with very delayed onset of an acquired lumbar epidural shunt, draining secondarily towards intradural veins and responsible for a venous congestive myelopathy with identical clinical symptoms.These patients require close clinical and imaging follow-ups in order to propose adequate treatments before onset of irreversible neurological deficits.
