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. 511 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 American Journal of Medicine's editorial office.
