An Error of Omission

We read with great interest a recent article entitled “Posterior Mediastinal Sarcoidosis” by Rosseel et al (Chest 1986; 90:462-64). As the authors indicate, posterior mediastmnal lymphadenopathy in sarcoidosis has rarely been recorded. It may be expected that frequent use of CT in these cases may change our current concept about the incidence of such involvement in the disease, and additional well-documented cases are valuable contributions. It appears, however, that there may be an inadvertent error in the selection of illustrations reproduced in the article. While Figure 1A shows right paratracheal and Figure 2B demonstrates right paratracheal, anterior tracheal, prevenous and prearterial lymph nodes, the sections illustrating posterior mediastinal nodes are omitted. Their inclusion would markedly increase the intrinsic value of the paper. D
