Predictive value of preoperative magnetic resonance imaging structural and diffusion indices for the results of trigeminal neuralgia microvascular decompression surgery
ConclusionNVC and RD of SpTV are independent risk factors for poor results after MVD surgery, and combining the NVC and RD might achieve relatively high predictive value for poor results. (Source: Neuroradiology)

Oligodendrogliomas tend to infiltrate the frontal aslant tract, whereas astrocytomas tend to displace it
ConclusionHigh sensitivity but low specificity for displacement in astrocytomas demonstrates that in the case of an astrocytoma, the tract is most likely displaced, but that displacement in itself is not necessarily predictive for astrocytomas, as oligodendrogliomas may both infiltrate and displace a tract. Overall, these results demonstrate that oligodendrogliomas tend to infiltrate the nearby subcortical tract, whereas astrocytomas only tend to displace it. (Source: Neuroradiology)

Increased pituitary volumes in patients with Sanfilippo syndrome (mucopolysaccharidosis type 3, MPS III)
ConclusionIn our
cohort of patients with Sanfilippo syndrome, whole, anterior, and posterior
pituitary volumes and degree of convexity along the upper pituitary border were
all significantly greater than controls. The cause of these morphological
changes is unclear, as is clinical correlation of the findings. (Source: Neuroradiology)

Congenital melanocytic naevus syndrome and Dandy-Walker malformation — a mistaken association: case report and literature review
AbstractCongenital melanocytic naevus (CMN) syndrome, previously termed neurocutaneous melanosis, is a rare disease caused by postzygotic mosaic mutations occurring during embryogenesis in precursors of melanocytes. The severity of neurological manifestations in CMN patients is related to central nervous system abnormalities found at magnetic resonance imaging. The association between CMN and Dandy –Walker malformation (DWM) has been described in the literature, but recent advances in imaging and genetics lead to diagnostic criteria revision. In this paper, we aim to re-evaluate the proposed association by reviewing the ...

Central tegmental tract hyperintensity: follow-up outcomes from a single-center study
ConclusionCTTH is a radiological finding commonly seen in early childhood but its clinical relevance has not been fully elucidated. While CTTH may be a transient phenomenon representing the maturation process, it may also be associated with a number of clinical conditions. Using a large patient series and follow-up MRI scans, our study shed light on the possible etiological factors of CTTH and its evolution over time. (Source: Neuroradiology)

Postsurgical dural supply to the spinal cord arteriovenous malformation in spinal arteriovenous metameric syndrome
AbstractDural supply from the external carotid system in cerebral arteriovenous malformations (AVMs) is well known, but actual angiographic evidence of dural supply to spinal cord AVMs (SCAVMs) has not been reported. Here, we report a case of dural supply to the conus SCAVM in the spinal arteriovenous metameric syndrome segment 25 –30. Thirteen years after spinal surgery (T12–L2 laminoplasty), spinal angiography showed multiple dural supplies from the dorsal somatic branches, prelaminar arteries, and radiculomeningeal arteries to the SCAVM at the level of the previous spinal surgery. To the best of our knowledge, this ...

The proximity between styloid process and internal carotid artery as a possible risk factor for dissection: a case –control study
ConclusionA short SP-ICA distance appears to be a risk factor for CAD as it likely induces a continuous microtraumatism of the vessel wall during normal head and neck movements. (Source: Neuroradiology)

The presence of pachymeningeal hyperintensity on non-contrast flair imaging in patients with spontaneous intracranial hypotension
ConclusionWhere present, diffuse pachymeningeal hyperintensity can be accurately identified on a non-contrast FLAIR sequence in patients with spontaneous intracranial hypotension. This potentially obviates the need for gadolinium base contrast agents in the work-up of these patients. (Source: Neuroradiology)

Detection of cerebral cortical vein thrombosis with high-resolution susceptibility weighted imaging — A comparison with MR venography and standard MR sequences
ConclusionSusceptibility weighted imaging demonstrates the best sensitivity and accuracy among standard MR sequences including MR venography for the detection of early stage cortical vein clots. However, it needs to be interpreted in combination with other MR sequences for the most accurate evaluation of cortical vein clots. (Source: Neuroradiology)

Association between thrombus composition and stroke etiology in the MR CLEAN Registry biobank
ConclusionThrombus composition is significantly associated with stroke etiology, with an increase in RBC and a decrease in F/P raising the odds for a non-cardioembolic cause. No difference between composition of cardioembolic thrombi and of undetermined origin was seen. This emphasizes the need for more extensive monitoring for arrhythmias and/or extended cardiac analysis in case of an undetermined origin. (Source: Neuroradiology)

Feasibility of percutaneous dural sac puncture via a posterior trans-sacral foraminal conduit approach: a CT morphometric analysis
AbstractWe assess the theoretical feasibility of percutaneous posterior sacral foramen (pSF) needle puncture of the sacral dural sac (DS) by studying the three-dimensional imaging anatomy of pSFs relative to the sacral canal (SC). On CT images of 40 healthy subjects, we retrospectively studied sacral alae passageways from SC to pSFs in all three planes to determine if an imaginary spinal needle could theoretically traverse S1 or S2 pSFs in a straight path toward DS. If not straight, we measured multiplane angulations and morphometrics of this route. We found no straight connections between S1 or S2 pSFs and SC. Instead, th...

Evaluation of extent vs velocity of cortical venous filing in stroke outcome after endovascular thrombectomy
ConclusionPoor CVF extent, as assessed by dCTA, is a more accurate and specific marker than slow CVF to identify patients at high risk for poor outcomes after ERT. (Source: Neuroradiology)
