Diagnostic dilemma

In those issues in which our regular Case of the Month does not appear, The Green Journal will present a Diagnostic Dilemma—an electrocardiogram or radiograph, or both, with a brief case history—as a challenge for our readers to solve. The correct answer appears on page 741. If you would like to contribute a Diagnostic Dilemma, please submit a high-quality copy of the electrocardiogram or radiograph with a brief synopsis (fewer than 250 words) of the case to the editorial office of The American Journal of Medicine.
