Annotated Bibliography #8
1. Suk I, Tamargo RJ. Concealed Neuroanatomy in Michelangelo’s Separation of Light From Darkness in the Sistine Chapel. Neurosurgery 66:851-861, 2010. First of all, you need to see this as a pdf or printed as color. Black and white will not do. I’m not sure I buy the optic nerve thing at the end of the paper, but I am totally convinced about the brainstem/throat connection (read the paper and that sentence will make sense).
2. Columbano L et al. Anatomic Study of the Quadrigeminal Cistern in Patients With 3-Dimensional Magnetic Resonance Cisternography. Neurosurgery 66:991-998, 2010. Seems like … Continue reading >>
Annotated Bibliography #7
1. Samartzis D et al. Atlantoaxial Rotatory Fixation in the Setting of Associated Congenital Malformations. Spine 2010;35:E119–E127. New subtypes to the Fielding and Hawkins classification scheme for atlantoaxial rotatory fixation should exist to account for variations in anatomy and the existence of congenital anomalies/malformations.
2. Kim KH et al. Adjacent Segment Disease After Interbody Fusion and Pedicle Screw Fixations for Isolated L4–L5 Spondylolisthesis. Spine 2010;35:625–634. A low postoperative segmental lordotic angle, especially less than 20°, at index level was related with development of clinical ASD in both isthmic and degenerative spondylolisthesis patients.

Al-Otaibi et al. Clinically silent magnetic resonance imaging findings after subdural strip electrode implantation. J Neurosurg 112:461–466, 2010. Clinically silent abnormalities were found in 100% of subjects, including subdural hematomas in 35, cortical contusions in 25%, local edema in 25%, trans–bur hole cortical herniation in 25%, subdural hygromas in 10% and pneumocranium.
Ebner FL, et al. Intramedullary lesions of the conus medullaris: differential diagnosis and surgical management. Neurosurg Rev (2009) 32:287–301. Straight forward and all inclusive review of lesions that affect the conus (or any other part of the spinal cord, for that matter). 117 references.

Annotated Bibliography #4
This is the latest in my series of posts titled Annotated Bibliography, that is, current literature titles which are generally not from the mainstream Radiology journals, but rather from related neuroscience fields which I have stumbled across and find of interest. Enjoy!
1. Mitochondrial Neurogastrointestinal Encephalopathy Due to Mutations in RRM2B. Arch Neurol. 2009;66(8):1028-1032. Just read the intro section and look at the images. I had never head of MNGIE before. The FLAIR images provided at least sort-of point to the diagnosis of “mitochondrial disease”.
2. Depletion of B Lymphocytes From Cerebral Perivascular Spaces by Rituximab. Arch Neurol… Continue reading >>
Annotated bibliography #3
The Use of Recombinant Human Bone Morphogenic Protein in Posterior Interbody Fusions of the Lumbar Spine, J Spinal Disord Tech 2009;22:315–320. Anterior, posterolateral and transforaminal approaches have shown good outcomes with this stuff, and this paper adds posterior interbody fusion to the list.
Clinical Usefulness of CT-myelogram Comparing With the MRI in Degenerative Cervical Spinal Disorders. Is CTM Still Useful for Primary Diagnostic Tool? J Spinal Disord Tech 2009;22:353–357 No surprise here, the answer is yes.

Case 17-2009: A 30-year-old man with progressive neurological deficits. NEJM 2009; 360:2341-51. I will not give this one away, but I am adding this entity to my list of pathologies which can mimic anything (lymphoma, TB, sarcoid). Come on admit it, you go to the end and look at the answer first!

Other Journals
I like features in the journals that keep you up to date with other literature, like the old annotated bibliography that AJNR used to have. In that spirit, I will throw out some current literature that you might not have run across:
Occurrence of Basal ganglia germ cell tumors without a mass. Arch Neurol 2009; 66(6): 789-792. Kinda scary. BG germ cell tumors, biopsy proven, presenting with volume loss and even wallerian degeneration. Also hypometabolism on PET.
The timing and influence of MRI on the management of patients with cervical facet dislocations remains highly variable. J Spinal Disord Tech 2009; … Continue reading >>
