AOSpine Masters Series, Volume 7: Spinal Cord Injury and Regeneration

Vialle LR, ed. Fehlings MG, Weidner N, guest eds. AOSpine Masters Series: Spinal Cord Injury and Regeneration. Vol 7. Thieme; 2016; 225 pp; 50 ill; $119.99

Vialle cover

The latest volume in the AOSpine Masters Series deals with spinal cord injury and regeneration. It should be a publication of interest to all neuroradiologists because it contains information that is not dealt with in common textbooks about spine radiology. The guest editors, Drs. Fehlings and Weidner, along with 25 contributors, address issues at the core of short-term and long-term care of patients with spinal cord injuries. The chapter on MR imaging covers important clinical/imaging correlates such as predicting outcomes based on MR and describing and annotating with technical factors the utility of advanced imaging protocol and more routinely employed MR protocols. The following chapters address topics other than pure imaging—such as the timing of surgery in acute spinal cord injury, the value of medical treatment, the potential role of neuroprotective schemes, materials used in attempts at neural repair and regeneration, the potential role of stem cell transplantation in SCI, and rehabilitative strategies for patients with spinal injuries—but are nonetheless of interest. Besides, the concepts of primary and secondary injury and the means of cord reconstitution are related to the very real, everyday issue of timing of possible surgery in acute SCI. The emphasis on the diminished effect of secondary injury (like vascular comprise/interruption) when decompressive surgery is performed within 24 hours posttrauma on a severely injured cord is summarized and discussed. Spinal Cord Injury and Regeneration is an important volume in this Spine Masters Series. It should appeal to all those who work closely with spine trauma surgeons, particularly in facilities where there is a sizeable rehab facility.…

Akoudad S, Wolters FJ, Viswanathan A, et al. Association of Cerebral Microbleeds With Cognitive Decline and Dementia. JAMA Neurol. 2016;73(8):934. doi:10.1001/jamaneurol.2016.1017.

The authors wanted to determine whether microbleed count and location were associated with an increased risk for cognitive impairment and dementia. They evaluated a prospective population-based study set in the general community, and assessed the presence, number, and location of microbleeds at baseline (August 2005 to December 2011) on brain MRI in 4841 participants 45 years or older. Trained research physicians, blinded to clinical data, reviewed the MRs. Cerebral microbleeds were defined as small, round to ovoid areas of focal signal loss on T2- weighted images. Participants underwent neuropsychological testing at 2 time points approximately 6 years apart, and were also followed up for incident dementia. 3257 participants underwent baseline and follow-up cognitive testing. Microbleed prevalence was 15.3%. The presence of more than 4 microbleeds was associated with cognitive decline. The presence of microbleeds was associated with an increased risk for dementia after adjustment for age, sex, and educational level, including Alzheimer dementia.

The strengths of this study, according to the authors, is the longitudinal population based design with a large sample size, the use of an extensive neuropsychological test battery, and the virtually complete screening for incident dementia. Limitations include multiple statistical tests, increasing the chance of type I errors. Second, selection bias may have influenced the results, because healthier people without subjective memory complaints were more likely to receive follow-up cognitive testing. Most importantly perhaps, the microbleed number may not reflect the true biological number because microbleed detection strongly depends on technical imaging methods used. T2W images were used, and as we know, SWI is far superior for the detection of these lesions.

Complications in Vascular Interventional Therapy: Case-Based Solutions

Steve Harvey, the entertainer who mistakenly crowned the wrong woman as Miss Universe 2015, once said, “Failure is a great teacher, and I think when you make mistakes and you recover from them and you treat them as valuable learning experiences, then you’ve got something to share.” While mistakes in medicine are never as laughable as his, this quote underscores one of the most powerful teachers in medicine: mistakes. Winston Churchill said, “All men make mistakes, but only wise men learn from their mistakes.” While local morbidity and mortality conferences allow groups to learn from one individual’s mistakes, fear of legal action or professional embarrassment engenders reticence to present and publish our own mistakes on a national or international stage. However, physicians everywhere know the value of learning from complications. For example, by popular demand, a local morbidity and mortality conference in Austria has morphed into a major international conference (International Conference on Complications in Interventional Radiology sponsored by the Cardiovascular and Interventional Radiology Society of Europe, or CIRSE).

This book presents a total of 106 cases (illustrated with 540 images). Each case provides patient history, initial/intended treatment, problems encountered, a list of possible bailouts of the complication, an explanation of which route was chosen and how it was carried out, and finally, an analysis of the complication. What makes the cases such good learning experiences is the fact that, despite many awful-looking initial complications, only one of the patients died (but likely because of his underlying condition rather than the complication). Therefore, in reading this book, one can learn of the plethora of endovascular complications that exist, and hopefully learn how to prevent their occurrence, or at the very least, …

CT and MR Imaging in the Diagnosis of Scleritis

Fellows’ Journal Club

Scleritis is a rare vision-threatening condition that can occur isolated or in association with other orbital abnormalities and whose etiology is typically inflammatory/noninfectious, either idiopathic or in the context of systemic disease. The authors analyzed 11 cases of scleritis in which CT and/or MR imaging were performed during the active phase of disease and assessed the diagnostic utility of these techniques. The most important imaging findings of scleritis were scleral enhancement, scleral thickening, and focal periscleral cellulitis. MR imaging is the recommended imaging technique.

Summary

Figure 1 from paper
Asynchronous IOID with scleritis. A, CECT depicts outward, eccentric thickening and enhancement of the right globe wall with focal periscleral cellulitis (black arrow), compatible with posterior scleritis. There is associated pre- and postseptal cellulitis (white arrow) and proptosis. B, CECT 18 months after examination (A) shows almost identical findings in the left orbit. Black and white arrows point to the scleritis and cellulitis, respectively. Notice the complete resolution of the alterations of the right orbit. Also, notice involvement of the tendon of the lateral rectus anteriorly (dashed arrow).

Scleritis is a rare, underdiagnosed vision-threatening condition that can occur isolated or in association with other orbital abnormalities. The etiology of scleritis is mainly inflammatory noninfectious, either idiopathic or in the context of systemic disease. Ultrasonography remains the criterion standard in diagnostic imaging of this condition but might prove insufficient, and studies on the diagnostic value of CT and MR imaging are lacking. We retrospectively analyzed 11 cases of scleritis in which CT and/or MR imaging were performed during the active phase of disease and assessed the diagnostic utility of these techniques. The most important imaging findings of scleritis were scleral enhancement, scleral thickening, and focal periscleral cellulitis. MR imaging is the recommended imaging technique, though posterior scleritis also can be accurately diagnosed on

Metabolic Abnormalities in the Hippocampus of Patients with Schizophrenia: A 3D Multivoxel MR Spectroscopic Imaging Study at 3T

Editor’s Choice

Nineteen patients with schizophrenia and 11 matched healthy controls underwent MR imaging and multivoxel point-resolved 1H-MRS at 3T to obtain their hippocampal gray matter absolute NAA, Cr, and Cho concentrations. Patients’ average hippocampal GM Cr concentrations were 19% higher than those of controls. NAA and Cho showed no differences. The authors conclude that the findings suggest the hippocampal volume deficit in schizophrenia is not due to net loss of neurons, which is in agreement with histopathology studies but not with prior 1H-MR spectroscopy reports. Elevated Cr would be consistent with hippocampal hypermetabolism.

Yield of Repeat 3D Angiography in Patients with Aneurysmal-Type Subarachnoid Hemorrhage

Fellows’ Journal Club

The purpose of this study was to evaluate the yield of repeat 3D rotational angiography in patients with aneurysmal-type SAH with negative initial 3D rotational angiography findings. Between March 2013 andJanuary 2016, 292 patients with SAH and an aneurysmal bleeding pattern were admitted, with 30 having initial negative 3D rotational angiography findings within 24 hours. These patients underwent a second 3D rotational angiography after 7–10 days. In 8/30 patients (over 26%) with initial negative 3D rotational angiography findings, a ruptured aneurysm wasfound on repeat 3D rotational angiography. The investigators conclude that repeat 3D rotational angiography is mandatory in patients with initial 3D rotational angiography findings negative for aneurysmal-type SAH.

Abstract

Figure 2 from paper
A 62-year-old woman with initial negative findings on 3DRA. A, 3DRA within 24 hours after SAH shows no aneurysm. B, Repeat 3DRA after 10 days shows an 8-mm supraclinoid internal artery dissecting aneurysm.

BACKGROUND AND PURPOSE

Aneurysmal-type subarachnoid hemorrhage is a serious disease with high morbidity and mortality. When no aneurysm is found, the patient remains at risk for rebleeding. Negative findings for SAH on angiography range from 2% to 24%. Most previous studies were based on conventional 2D imaging. 3D rotational angiography depicts more aneurysms than 2D angiography. The purpose of this study was to evaluate the yield of repeat 3D rotational angiography in patients with aneurysmal-type SAH with negative initial 3D rotational angiography findings and to classify the initial occult aneurysms.

MATERIALS AND METHODS

Between March 2013 and January 2016, 292 patients with SAH and an aneurysmal bleeding pattern were admitted. Of these 292 patients, 30 (10.3%; 95% CI, 7.3%–14.3%) had initial negative 3D rotational angiography findings within 24 hours. These patients underwent a second 3D rotational angiography after 7–10 days.

RESULTS

In 8 of 30 patients (26.7%; 95% CI, 14.0%–44.7%) with initial negative 3D

Comparison of Quantitative Cerebral Blood Flow Measurements Performed by Bookend Dynamic Susceptibility Contrast and Arterial Spin-Labeling MRI in Relapsing-Remitting Multiple Sclerosis

Editor’s Choice

Both dynamic susceptibility contrast perfusion with bookend T1-calibration and pseudocontinuous arterial spin-labeling have been used recently for CBF quantification in relapsing-remitting MS. The authors compared pseudocontinuous arterial spin-labeling CBF with the bookend technique in a prospective cohort of 19 healthy controls, 19 subjects with relapsing-remitting MS without cognitive impairment, and 20 subjects with relapsing-remitting MS with cognitive impairment. Voxelwise paired t tests revealed no significant CBF differences between techniques after normalization of global meanintensities. They conclude that there is agreement between pseudocontinuous arterial spin-labeling and bookend technique CBF measurements in healthy controls and patients with relapsing-remitting MS.
