BACKGROUND AND PURPOSE The purpose of this work was to study the validity of MR angiography (MRA) for identification of spinal arteriovenous (AV) abnormalities. MATERIALS AND METHODS Thirty-four consecutive patients with suspicion of spinal vascular abnormalities underwent digital subtraction angiography (DSA) after MRA. The level and side of the suspected spinal dural arteriovenous fistula (...

Key highlights: Tabular columns organized by anatomical abnormality include imaging findings and a summary of key clinical data that correlates to the images Congenital/developmental abnormalities, spinal deformities, and acquired pathologies in both children and adults Lesions organized by region including dural, intradural extramedullary, extra-dural, and sacrum More than 600 figures illustra...

The present study describes the imaging findings in a patient with dural arteriovenous fistula (AVR) and arteriovenous malformation (AVM) with bilateral subcortical and basal ganglia calcification. A 29 year old male patient presented with chief complaint of recent onset of generalized tonic clonic seizures and mild disorientation. The imaging studies on MCT demonstrated diffuse, symmetric calc...

Spinal anesthesia is one of the most used anesthetic techniques, having been in existence for over 100 years, and time it has improved by development a new needle design, gauge, tip shapes, as well more precise indications contraindications. However, even so, there are still possible complications due to this procedure, especially headache after puncture dura mater, and, because that, procedure...

BACKGROUND AND PURPOSE For the localization of spinal dural arteriovenous fistulas, it is not determined whether dynamic contrast-enhanced MRA is more reliable than multidetector CTA. The aim of this study was to compare the agreement between intra-arterial DSA, dynamic contrast-enhanced MRA at 3T, and 64-row multidetector CTA for the localization of spinal dural arteriovenous fistulas.
