Nice collections of cases, great quality pics and good discussion about each disease. But it misses DDx and findings discussion (ok, dr. Yousem has it in a pdf file on his website, but this is not practical). I recommend the case review authors to give a look at Mayo Clinic GI Imaging and Dr. Chew's MSK Teaching Files which are better case books (ok, they're more expensive, but are also more useful).
