A Dictionary of Hallucinations
Blom JD. A Dictionary of Hallucinations. Springer 2010, 553 pages, 100 illustrations, $99.00.
Although this clearly is not a neuroradiology textbook, it is nonetheless fascinating.
The author of this 500-page hardcover book, Dr. Jan Dirk Blom, has compiled innumerable short vignettes related to a host of different medical terms, biographical sketches, physiological phenomena, psychological disorders, geophysical observations, and the like, most of which seem to have had their origin from imaginings, frank hallucination, dreams, or the disclosures of mysterious “facts.” The list of described features is amazing — who was Charles Dogeon, how to explain the moon illusion (or … Continue reading >>

SIH (Spontaneous intracranial hypotension). Why should we ban “CSF hypovolemia” ? Because it’s a misnomer
Spontaneous intracranial hypotension (SIH) is now a fairly well known syndrome. Leakage of CSF is considered the pathogenetic factor, even in cases in which it is not demonstrated.
The loss of CSF volume explains the usual complaint of orthostatic headache, relieved by lying down, and the characteristic MRI findings: 1) thickening of the dura, enhancing after contrast medium administration, 2) subdural fluid collections, 3) sagging of the brain, 4) dilatation of the venous structures, which includes enlargement of the dural sinuses and veins, enlargement of the pituitary gland, and, in the spinal canal, engorgement of the epidural plexuses. All these … Continue reading >>

Annotated Bibliography #9
1. Zhang Q, Raoof M, et al. Circulating mitochondrial DAMPs cause inflammatory responses to injury. Nature (letters) Vol 464,4 March 2010. You will need a glossary for this paper: DAMP = ‘damage’-associated molecular pattern. Cellular disruption by trauma will release mitochondrial DAMPs with evolutionarily conserved similarities to bacterial ‘pathogen-associated molecular patterns’ into the circulation which signal through innate immune pathways (identical to those activated in sepsis) to create a sepsis-like state. Or just read #2 paper below for a translation of the findings to something understandable by mortals.

Apparent Diffusion Coefficient of Glial Neoplasms: Correlation with Fluorodeoxyglucose–Positron-Emission Tomography and Gadolinium-Enhanced MR Imaging • A.I. Holodny, S. Makeyev, B.J. Beattie, S. Riad, and R.G. Blasberg
The authors state that contrast enhancement does not always correlate with tumor histology and thus they compared the findings of FDG-PET and apparent diffusion coefficient maps to postcontrast MR images in 21 patients with cerebral glial neoplasias. All images were subjectively and objectively evaluated and correlation coefficients calculated for all regions of interest analyzed. Subjective evaluation showed a 60% correlation between PET and ADC with a greater overlap between PET and ADC … Continue reading >>

A Prospective Trial of 3T and 1.5T Time-of-Flight and Contrast-Enhanced MR Angiography in the Follow-up of Coiled Intracranial Aneurysms • T.J. Kaufmann, J. Huston III, H.J. Cloft, J. Mandrekar, L. Gray, M.A. Bernstein, J.L. Atkinson, and D.F. Kallmes
Other past articles have dealt with comparisons between DSA and contrast enhanced MRA for detection of residual post treatment aneurysms. This article deals with a similar topic but addresses the question of which is better for MRA in this situation: 1.5T or 3.0T? The authors prospectively studied 63 coiled aneurysms within one week of obtaining DSA in them all. The … Continue reading >>
