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 and/or radiograph with a brief case history—for our readers to solve. The correct answer appears on p. 262 of this issue. If you would like to contribute a Diagnostic Dilemma, please submit a high-quality copy of the EKG or radiograph with a brief synopsis (<250 words) of the case to the AJM editorial office.
