title: Diagnostic dilemma.
abstract: 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 742. If you would like to contribute a Diagnostic Dilemma, please submit a high-quality copy of the ECG or radiograph with a brief synopsis (<250 words) of the case to editorial office of the American Journal of Medicine.
