Mayo Clinic Challenging Images for Pulmonary Board Review is a collection of over 150 entities selected from over 1,500 examples of very unusual intrathoracic conditions, spanning more than 45 years of service by a highly respected clinician. Appropriate images of all these conditions are shown along with the "pearls" of how to interpret the chest x-ray and other images. As the old adage says, a picture is worth a thousand words, so by spending a few minutes, or less, on each of the 100+ conditions, the reader won't forget what he or see saw, thereby possibly saving the patient expensive, sometimes invasive surgeries including thoracotomy, procedures. This will be indispensable resource for every pulmonologist, thoracic surgeon, and radiologist.
