- Epileptogenic Tubers Are Associated with Increased Kurtosis of Susceptibility Values: A Combined Quantitative Susceptibility Mapping and Stereoelectroencephalography Pilot Study
Ten patients with tubers related to tuberous sclerosis complex underwent quantitative susceptibility mapping. The QSM and R2* distributions from tubers studied with stereoelectroencephalography demonstrated that increased kurtosis of quantitative susceptibility mapping values was highly specific and associated with epileptogenicity.
- Resisted Inspiration Improves Visualization of CSF-Venous Fistulas in Spontaneous Intracranial Hypotension
This retrospective cohort of patients with observed or suspected CSF-venous fistula identified during standard maximum suspended inspiration CT myelography were rescanned using resisted inspiration and the Valsalva maneuver. Visibility of the CSF-venous fistula was greatest during resisted inspiration in most of the cases.
- Ecchordosis Physaliphora: Does It Even Exist?
Notochordal lesions span a spectrum of disease ranging from benign notochordal remnant (ecchordosis physaliphora) to low-grade to aggressively malignant. Benign notochordal remnant cannot be reliably distinguished from low-grade chordoma as they may have overlapping imaging features. Repeat imaging, beginning at 6-month intervals, is a more clinically relevant method for evaluating the malignant potential of these lesions.
