Atlas of Neurosurgical Techniques (2-Volume Set)

Sekhar LN, Fessler RG, eds. Atlas of Neurosurgical Techniques. Vols 1 and 2. 2nd ed. Thieme; 2015; 1566 pp; 2775 ill; $449.99

sekhar-fessler_atlas-neurosurg-techniques_coverWhile a majority of neuroradiologists, except those in interventional neuroradiology, may not be enticed to purchase their own personal copy of the 2-volume set Atlas of Neurosurgical Techniques: Brain, it should be recognized by all those in the clinical neurosciences that this deals with for more than “techniques”. Edited by Drs. Sekhar (University of Washington) and Fessler (Rush University Medical Center), this 1566-page book set is the second edit (prior publication 2006) of this authoritative text, and it fulfills all expectations.

Volume 1 covers in great detail General Principles and Basic Techniques (8 chapters), Aneurysms (19 chapters), AVMs (13 chapters), Occlusive and Hemorrhagic Vascular Disease (6 chapters), Intraventricular Tumors (2 chapters), Pineal Region Lesions (4 chapters), Cranial Base Lesions (27 chapters), Epilepsy and Functional Pain Disorders (3 chapters), Cranial Nerve Compression Syndromes (8 chapters), Cranio-Cerebral Trauma (2 chapters), Hydrocephalus (2 chapters), CNS Infections (1 chapter), Stereotatic Radiosurgery (5 chapters). A multitude of video clips (over 150) accompany the 2 volumes. One accesses those videos via codes given with the book (separate code for each volume). As one reads material in each section, they are referred back to an appropriate video.

Considerable space (310 page) is devoted to aneurysms and their treatment, and with the drawings, the associated angiograms, and the pre/postoperative imaging, one develops an understanding of the techniques (open and endovascular) used in both common and complex aneurysms. Each chapter in this section (and, in fact, throughout the entire set of books) follows about the same—but not identical—outline, with items of interest to radiologists, such as case material (history, imaging, procedure), patient selection, choices for approach, vivid intraoperative photographs (where applicable), operative approaches, drawings as … Continue reading >>

We Are Retiring the Clinical Correlation

12-dec-aThe Clinical Correlation, one of several features within the AJNR‘s Case Collections section, is being retired.

Originally envisioned by Section Editor Dr. Christine Glastonbury (from the University of California, San Francisco) as a way to stoke collaboration between neuroradiologists, pathologists, and clinicians, the Clinical Correlation ran from October 2013 through December 2015. In that time, Dr. Glastonbury — with the help of Associate Editors Drs. Matthew S. Russell, Tarik Tihan, S. Andrew Josephson, and Phiroz Tarapore, all of whom also hail from UCSF — amassed a collection of cases matching imaging with pathology, often featuring video and audio components to help demonstrate these correlations. We hope our readers have found the Clinical Correlation to be a useful series of cases for learning how neuroradiologic information contributes to and corresponds with important clinicopathologic findings in a number of disease entities.

The AJNR would like to thank Dr. Glastonbury and her Associate Editors for the time and effort they devoted to producing this feature. The case archive will be accessible from the About page at AJNR.org, where site visitors will be able to browse installments either by date or by diagnosis.… Continue reading >>

AJNR Welcomes New Statistical Senior Editor

Bryan Comstock, MS

Bryan Comstock, MS

The AJNR would like to welcome Bryan Comstock, MS, who joined us as our first Statistical Senior Editor on October 1. Manuscripts submitted to AJNR now undergo separate statistical review, during which they are assessed for the statistical validity of their findings and for study design. We hope this added level of scrutiny will further improve the quality of papers we publish and also help authors to revise and refine their work during review.

Bryan is Senior Biostatistician at the Center for Biomedical Statistics at the University of Washington in Seattle, where he develops and supports grant applications for extramural funding in the areas of health services research, radiology, neonatology, nephrology, and surgery. He has served as the primary biostatistician for numerous randomized clinical trials and observational cohort studies and has developed electronic data capture systems for multisite randomized studies. He is a member of the Society of Clinical Trials and the co-author of more than 50 peer-reviewed articles indexed on MEDLINE.… Continue reading >>

In Memoriam – Georges Salamon

salamon_obitGeorges Salamon, one of neuroradiology’s pioneers, early thought leaders, and international spokesmen died on October 10, 2015, at age 84. Born in Montpellier, France to a Russian father and a Polish mother of Jewish descent, he acutely experienced the traumas of World War II, but kept throughout his life a unique, optimistic spirit of adventure. Knowing the costs and benefits of the vicissitudes of life, Georges maintained an exceptional open-mindedness and a zest for change and new opportunities.

Receiving his Doctor of Medicine from the Faculty of Aix-Marseille in 1958, he was spurred into specialty training by his teachers, Herman Fischgold, Henri Gastaut, and Robert Naquet, graduating in radiology in 1962 and neurology in 1965. This dual experience in imaging and neuroscience provided the stimulus for Georges to enter the nascent field of Neuroradiology and the basis of a prestigious career bridging these disciplines. Post training, Georges quickly joined the Hôpital de la Timone in that “considerable town,” Marseille, first as assistant professor in 1964, and then as head of the Department of Neuroradiology from 1972 to 1996.

Though broadly curious and an eclectic thinker, Georges’ first scientific love was neuroanatomy. Between 1965 and 1970 his students’ numerous theses on cerebral vasculature formed the basis of and culminated in the publication of the Atlas of Arteries of the Human Brain in 1974, of Radiologic Anatomy of the Brain in collaboration with Y.P. Huang in 1978, and Vascularization and Cerebral Circulation with G. Lazorthes and A. Gill that same year. This work became the anatomic bible for a whole generation of neuroradiologists and neurosurgeons. It also served as a basis for the subsequent development of therapeutic angiography and the emergence in France of a new generation of vascular neuroradiologists under the joint stimulus of Georges Salamon and René Djindjian.

Differentiation between Cystic Pituitary Adenomas and Rathke Cleft Cysts: A Diagnostic Model Using MRI

Fellows’ Journal Club

Editor’s Comments

This is a retrospective study that included 54 patients with a cystic pituitary adenoma and 28 patients with a Rathke cleft cyst who underwent MR imaging followed by surgery. Regression analysis showed that cystic pituitary adenomas and Rathke cleft cysts could be distinguished on the basis of the presence of a fluid-fluid level, septation, an off-midline location, and the presence of an intracystic nodule.

Abstract

Diagnostic decision tree for the differentiation of cystic pituitary adenomas and RCCs using MR imaging.

Diagnostic decision tree for the differentiation of cystic pituitary adenomas and RCCs using MR imaging.

BACKGROUND AND PURPOSE

Cystic pituitary adenomas may mimic Rathke cleft cysts when there is no solid enhancing component found on MR imaging, and preoperative differentiation may enable a more appropriate selection of treatment strategies. We investigated the diagnostic potential of MR imaging features to differentiate cystic pituitary adenomas from Rathke cleft cysts and to develop a diagnostic model.

MATERIALS AND METHODS

This retrospective study included 54 patients with a cystic pituitary adenoma (40 women; mean age, 37.7 years) and 28 with a Rathke cleft cyst (18 women; mean age, 31.5 years) who underwent MR imaging followed by surgery. The following imaging features were assessed: the presence or absence of a fluid-fluid level, a hypointense rim on T2-weighted images, septation, an off-midline location, the presence or absence of an intracystic nodule, size change, and signal change. On the basis of the results of logistic regression analysis, a diagnostic tree model was developed to differentiate between cystic pituitary adenomas and Rathke cleft cysts. External validation was performed for an additional 16 patients with a cystic pituitary adenoma and 8 patients with a Rathke cleft cyst.

RESULTS

The presence of a fluid-fluid level, a hypointense rim on T2-weighted images, septation, and an off-midline location were more common with pituitary adenomas, whereas the presence of an intracystic nodule was
