Pulmonary cryptococcosis mimicking neoplasm in terms of uptake PET/CT

Avenida Doutor Arnaldo, 455, Pacaembu. São Paulo, SP, Brazil, 01246-903. E-mail: [email protected]. All 20 reports were reviewed and defined as follows: “not described”—when features of EFN were overlooked; “described but not suggested”—when EFN features were described but the diagnosis was not suggested in the report; and “suggested”—when EFN findings were described and its diagnosis was suggested. The outcome was surprising. As shown in Figure 2, we found a progressive number of diagnoses over the years, especially after 2013. In 2011, when radiologists were still unaware of the entity, the number of correct diagnoses was zero. In 2014, Figure 2. The 4-year progression of EFN diagnosis data at a single institution. after the educational intervention, there were no more missed diagnoses of EFN at the institution. We can suggest that the dissemination of knowledge at our institution changed the pattern of the diagnosis of a disease. We believe that, in the next few years, EFN will become known worldwide, the labels “rare” and “unknown” therefore no longer being associated with this entity.
