What is the Prevalence of a “Nontherapeutic” Thymectomy?

In this study, 27.8% of thymectomies were nontherapeutic, and most patients underwent an open approach. The most common benign diagnosis was thymic hyperplasia, a condition for which magnetic resonance imaging has a high predictive value. Consequently, further studies are warranted to determine the optimal evaluation of patients undergoing thymectomy for presumed thymoma.
