Here it is again, the January 2014 UNC Neuroradiology Neuropathology conference. It contains some rare and cool cases. We hope you enjoy it!
In June, 2015, Mauricio Castillo, MD, FACR, will complete an eight-year term as the Editor-in-Chief of the AJNR. He follows a short list of illustrious neuroradiologists, from Dr. Juan Taveras to Dr. Michael Huckman to Dr. Robert Quencer to Dr. Robert Grossman.
One only has to pick up any random issue of the AJNR to realize what a tremendous mark Mauricio has made on the journal. His imprint starts on the first page of content with his column, Perspectives. Probing, erudite, at times very witty, and always brilliant, Mauricio turns out a monthly commentary on the state of neuroradiology, … Continue reading >>
Diffusion MRI Improves the Accuracy of Preoperative Diagnosis of Common Pediatric Cerebellar Tumors among Reviewers with Different Experience Levels
Fellows’ Journal Club
(3 of 3)
DWI studies of 96 cerebellar pediatric tumors were analyzed by neuroradiologists and residents in radiology during 2 sessions, one that included the DWI studies and one that did not. These observers were asked to categorize the masses as: astrocytoma, medulloblastoma, ependymoma, or atypical teratoid/rhabdoid tumor. The addition of DWI resulted in significant improvement in the diagnosis of all tumors except ependymoma among all reviewers with different levels of experience.
BACKGROUND AND PURPOSE
Although utility of diffusion MR imaging in the preoperative diagnosis of common pediatric cerebellar tumors is generally recognized, its … Continue reading >>

Dr. Crues is a radiologist whose experience in MR imaging is vast, and … Continue reading >>
Subcortical Cystic Lesions within the Anterior Superior Temporal Gyrus: A Newly Recognized Characteristic Location for Dilated Perivascular Spaces
Fellows’ Journal Club
(2 of 3)
Fifteen patients with unusual dilated perivascular spaces in the subcortical white matter of the anterior superior temporal gyrus were presented. In one, pathology showed gliosis and innumerable perivascular spaces. Findings that suggest cysts in this location were perivascular spaces include: lack of symptoms, proximity to the subarachnoid space, adjacent blood vessels, and stability over time.
Cystic parenchymal lesions may pose an important diagnostic challenge, particularly when encountered in unexpected locations. Dilated perivascular spaces, which may mimic cystic neoplasms, are known to occur in the inferior basal ganglia and mesencephalothalamic regions; a … Continue reading >>
Saraf-Lavi E. Spine Imaging: Case Review Series. 3rd Ed. Elsevier; 2013; 352 pgs; $69.95.
The 3rd edition of Spine Imaging is the most recent addition to the popular Case Review Series. The text is a case-based presentation of 160 spine cases. In each case, a series of images is presented along with a brief history. The reader is then given a series of questions relevant to the topic and asked to identify the pathology. For each case, there is a detailed description of the pathology, a differential diagnosis, and a discussion of relevant imaging findings.
The cases … Continue reading >>
Runge VM, Nitz WR, Trelles M, et al. The Physics of Clinical MR Taught Through Images. 3rd Ed. Thieme; 2013; 288 pgs; $64.99.
For a clinical radiologist, understanding MR physics is a challenge and becomes even more so as new MR techniques and updated software programs become integrated into our daily work routine.
In this 288-page softcover book, The Physics of Clinical MR Taught Through Images, written by Drs. Runge, Nitz (PhD), Trelles, and Goerner (PhD), 123 topics, each of approximately 2 pages in length, address virtually all pertinent issues in the physics of MR. As the title … Continue reading >>
Simmen D, Jones N. Manual of Endoscopic Sinus and Skull Base Surgery. 2nd Ed. Thieme; 2013; 468 pgs; 1442 illustrations; $199.99.
Clearly designed for the ENT surgeon, Manual of Endoscopic Sinus and Skull Base Surgery by Drs. Simmen and Jones is a highly visual text centered primarily, but not exclusively, around the paranasal sinuses, with an abundant number of intraoperative photographs. For the radiologist with interest in head and neck imaging, the book has much to offer, though not with regard to the very short chapter titled “The Place of Radiology” as much as anatomic variants, surgical danger … Continue reading >>
Utility of Proton MR Spectroscopy for Differentiating Typical and Atypical Primary Central Nervous System Lymphomas from Tumefactive Demyelinating Lesions
Fellows’ Journal Club
(1 of 3)
The utility of MRS in differentiating lymphoma from tumefactive demyelination was assessed in 44 patients with the former and 21 with the latter. A Cho/Cr over 2.58 and a high lipid/lactate peak were more common in lymphoma, therefore MRS may help in differentiating these 2 entities.
BACKGROUND AND PURPOSE
It may be challenging to differentiate primary CNS lymphomas, especially primary CNS lymphomas with atypical MR features, from tumefactive demyelinating lesions by the use of conventional MR. This study aimed to investigate the usefulness of 1H-MR spectroscopy for making this discrimination.
MATERIALS … Continue reading >>

Written primarily with medical students in mind, but also for those in allied fields who may wish to have a survey of the field of radiology, Essential Radiology: Clinical Presentation, Pathophysiology, Imaging accomplishes that goal. It cuts a broad sweep across radiology, covering all systems with a truncated atlas of cross-sectional anatomy and a general chapter on the introduction to radiology. For those associated with medical schools where radiology is a required course for medical students, this book could serve as … Continue reading >>
Portions of this post originally appeared in an editorial by Mauricio Castillo in the January 2014 issue. They have been reproduced here in modified form.
As many of our readers may know by now, we are terribly saddened by the passing of our colleague and Senior Editor, Dr Lucien Levy. Lucien brought with him considerable enthusiasm and knowledge regarding advanced neuroimaging and was a true gentleman. An obituary with details about his life is also published in this issue of the American Journal of Neuroradiology (AJNR).
We welcome Dr Jody Tanabe as our new Senior Editor … Continue reading >>
Waldt S, Eiber M, Woertler. Measurements and Classifications in Musculoskeletal Radiology. Thieme; 2013; 224 pgs.; 423 illustrations; $129.99.
Measurements and Classifications in Musculoskeletal Radiology is a relatively slim 224-page reference text for key measurements in MSK imaging. The book is organized into 17 chapters, each covering topics ranging from joint anatomy, tumor classification, grading of cartilage and muscle injuries, and, most relevant to readers of AJNR, important measurements used in exams of the spine and craniocervical junction. The authors’ goal is to provide “a handy reference for everyday use” that covers a variety of measurement schemes and classifications … Continue reading >>
