Linzey JR, Wilson TJ, Sullivan SE, Thompson BG, Pandey AS. Frontal Sinus Breach During Routine Frontal Craniotomy Significantly Increases Risk of Surgical Site Infection: 10-Year Retrospective Analysis. Neurosurgery. 2017;0(0):1-8. doi:10.1093/neuros/nyx046.

Frontotemporal craniotomies are at particular risk for breaching the frontal sinus, especially when the patient has a large frontal sinus or the surgeon is attempting to expose anterior communicating (ACOM) artery aneurysms. Frontal sinus breach (FSB) has the potential to cause postoperative complications due to the introduction of microflora from the frontal sinus into the sterile environment of the intracranial compartment. 

In this retrospective study, the authors are attempting to determine if FSB is a risk factor for developing cranial surgical site infections in patients undergoing craniotomies for clip ligation of anterior circulation aneurysms. They hypothesized that the surgical site infection (SSI) rate for craniotomies with an FSB would be significantly higher than for craniotomies without an FSB, given the contamination of the intracranial compartment during FSB. This study included 862 patients undergoing 910 craniotomies. Primary outcome of interest was occurrence of a cranial surgical site infection. Of the 910 craniotomies, 141 (15.5%) involved FSB. Of those involving FSB, 22 (15.6%) developed a cranial surgical site infection, compared to only 56 of the 769 without FSB (7.3%). Cranial surgical site infection requiring reoperation was much more likely in patients with FSB compared to those without a breach (7.8% vs 1.6%). Patients with FSBs had 2 times the odds of developing a cranial surgical site infection as those without FSB. The authors overall infection rate of 8.6% for craniotomies is comparable with other published data.  In addition, the length of surgical procedure was associated with increased risk of infection, which supports previously published data.  As expected, longer procedures were also more common in patients with FSB compared to those …

Localizing the L5 Vertebra Using Nerve Morphology on MRI: An Accurate and Reliable Technique

Fellows’ Journal Club

The authors sought to determine whether the L5 vertebra could be accurately localized by using nerve morphology on MR imaging. A sample of 108 cases with full spine MR imaging were numbered from the C2 vertebral body to the sacrum. The reference standard of numbering by full spine imaging was compared with the nerve morphology numbering method with 5 blinded raters. The percentage of perfect agreement with the reference standard was 98.1%, which was preserved in transitional and numeric variation states. The iliolumbar ligament localization method showed 83.3% perfect agreement with the reference standard.

Improved Detection of Anterior Circulation Occlusions: The “Delayed Vessel Sign” on Multiphase CT Angiography

Fellows’ Journal Club

The authors evaluated 23 distal anterior circulation occlusions during a 2-year period. Ten M1-segment occlusions and 10 cases without a vessel occlusion were also included. There was significant improvement in the sensitivity of detection of distal anterior circulation vessel occlusions, overall confidence, and time taken to interpret with multiphase CTA compared with single-phase CTA. The delayed vessel sign is a reliable indicator of anterior circulation vessel occlusion, particularly in cases involving distal branches.

Multicenter Experience with FRED Jr Flow Re-Direction Endoluminal Device for Intracranial Aneurysms in Small Arteries

Editor’s Choice

The authors assessed the clinical safety and efficacy of the Flow Re-Direction Endoluminal Device Jr (FRED Jr) dedicated to small-vessel diameters between 2.0 and 3.0 mm in 42 patients with 47 aneurysms. The primary efficacy end point of complete or near complete occlusion was reached at 1 month in 27/41 (66%), at 6 months in 21/27 (78%), and at 12 months in 11/11 (100%) aneurysms.

In Memoriam – William Werner Orrison Jr (1949-2017)

William Werner Orrison 

William Werner Orrison died at age 68 on Oct. 19, 2017, in Las Vegas, Nev., of a non-specified neuro-degenerative disorder.

Born on April 2, 1949, in Louisville, Ky., Bill was the eldest child of Agnes Rutherford Miller “Ruth” Orrison, R.N., and William Werner Orrison Sr., M.D., known as Werner. Bill grew up in Minneola, Plains, and Meade, Kans., where his father was among the last generation of country doctors, often making house calls to remote farms, equipped only with the contents of a black bag, sometimes accepting livestock as payment. From his earliest years, Bill witnessed his father’s devotion to humble patients and dreamed of joining him in practice as a medical doctor.

Bill graduated in 1967 from Meade High School, an Eagle Scout and an accomplished trick horseback rider. As a teen, while on a fishing trip with Werner, Bill suffered a freak accident that put him in the first of three near-death states during his life. Bill later described being drawn into a “tunnel of fog” while his father performed an emergency tracheotomy to save his son’s life. Attending the University of Kansas in Lawrence on an ROTC scholarship, Bill rose to commander of his Air Force squadron, but at the Phi Gamma Delta house he was known as “Doc,” for his unlicensed diagnostic skills. After Bill earned the lowest score in the class on his first chemistry test, the professor encouraged him to try another major. By semester’s end, Bill had the highest grade among his peers. He graduated from KU in 1971 and remained a lifelong fan of Jayhawk basketball.

While at KU, Bill attended a talk by the Maharishi Mahesh Yogi, discovering that the hypnosis his father had used on patients in the absence of anesthesia …

Multinodular and Vacuolating Neuronal Tumor of the Cerebrum: A New “Leave Me Alone” Lesion with a Characteristic Imaging Pattern

Fellows’ Journal Club

The most recent 2016 WHO classification includes MVNT as a unique cytoarchitectural pattern of gangliocytoma, though it remains unclear whether MVNT is a true neoplastic process or a dysplastic hamartomatous/malformative lesion. The authors report 33 cases of presumed multinodular and vacuolating neuronal tumor of the cerebrum that exhibit a remarkably similar pattern of imaging findings consisting of a subcortical cluster of nodular lesions. They conclude that these are benign, nonaggressive lesions that do not require biopsy in asymptomatic patients and behave more like a malformative process than a true neoplasm.

Concordance of Time-of-Flight MRA and Digital Subtraction Angiography in Adult Primary Central Nervous System Vasculitis

Editor’s Choice

The authors compared the diagnostic concordance of vessel imaging using 3D-TOF-MRA and DSA in 85 patients with primary central nervous system vasculitis. Among the 25 patients with abnormal DSA findings, 24 demonstrated abnormal 3D-TOF-MRA findings, whereas all 6 remaining patients with normal DSA findings had normal 3D-TOF-MRA findings. They conclude that 3D-TOF-MRA shows a high concordance with DSA in diagnostic performance when analyzing vasculature in patients with primary central nervous system vasculitis and that with negative 3T 3D-TOF-MRA findings, the added diagnostic value of DSA is limited.

Advanced Neuroradiology Cases: Challenge Your Knowledge

Amaral LLF do, Bag AK, Guimarães Gonçalves F, Hanagandi PB, eds. Advanced Neuroradiology Cases: Challenge Your Knowledge. Cambridge; 2017; 544 pp; $160.00

Advanced Neuroradiology Cases Challenge your Knowledge

Advanced Neuroradiology Cases is a compilation of uncommon but important diagnoses in neuroimaging. The primary audience of the book includes neuroradiologists, neuroradiology fellows, neurosurgeons, and neurologists. There are 8 chapters that include information about degenerative, vascular, infectious, inflammatory, metabolic, neoplastic, congenital, and miscellaneous diseases of the brain.

The text is organized in a case-based fashion, with a clean and concise delivery. Each case begins with a detailed clinical description and is followed by selective key imaging. The authors provide a relevant discussion of the diagnosis and explain why other entities in the differential diagnosis would be considered less likely. Important information regarding clinical or pathologic confirmation of the diagnosis is also typically provided. Each case ends with a summary of key points, facilitating easier recall of the pathologies for the reader.

When confronted with challenging cases, one’s approach and final interpretation is often limited by their fundamental knowledge base. The information contained in this book may seem somewhat obscure, but it provides valuable exposure to rare pathologies. The text not only serves to enhance radiologists’ existing knowledge, but also provides access to material that would not otherwise be readily attained from performing an internet search or literature review. Furthermore, the book provides reinforcement of key concepts in advanced neuroimaging.

The chapter on neurodegenerative diseases would be of particular interest to neurologists in their workup of cognitive dysfunction and movement disorders. The chapter on neuroinfectious diseases offers exposure to entities that may not be commonly encountered by those practicing in nonendemic areas but can be seen in patients native to those regions. The chapter on metabolic diseases aids in the approach to generating a differential diagnosis in these …
