Case of the Week
I would like to thank Dr Castillo for providing me the opportunity to be the section editor for the AJNR Case-of-the-Week (COW). It has been about 4 months since I assumed this responsibility and, I would also like to take this opportunity to thank colleagues from all over the world toward their contribution to the COW.
It has been about 2 – 3 years since COW was introduced by Dr Castillo. It has grown to be a tremendously popular site (sometimes receiving up to 10,000 views per month). With the hope of adding to the educational content of COW, Dr. … Continue reading >>

Cases of the Week
The case of the week feature is very popular. We now have over 18 months of cases accumulated. Every week, more than 5000 individuals (at times as close to 8000!) look at them. The database can be searched by diagnosis and or blindly by date of posting. The cases are illustrative and their degree of difficulty varies making them interesting for individuals with all levels of knowledge in neuroradiology. It is my desire, that residents and fellows will used them to study. Submissions are open only to fellows in Neuroradiology. Since AJNR and other journals accept very few case reports, … Continue reading >>
