The authors present a radiographic image portraying the "thymic sail sign" and the "thymic wave sign," both normal findings in infant radiographs and present a short description of these signs. These are distinguished from pathologic findings such as the "spinnaker-sail sign" in pneumomediastinum.

Perineal groove is a rare congenital anorectal malformation, with incidence yet undetermined. It is almost exclusive to the female newborn and its embryogenic origin remains uncertain. We present a case-report of a newborn girl that was discharged from the nursery without complications. At her first appointment at primary care we noted a wet sulcus connecting the posterior vaginal commissure CASO CLÍNICORevista Científica da Ordem dos Médicos www.actamedicaportuguesa.com 671 Barbosa M, et al.

A 64-year-old man presented with unintentional weight loss of 22 kg in the preceding 9 months, cough, night sweating and low-grade fever. The lag time between onset of symptoms and first medical visit was explained by a long history of homelessness and intravenous drug abuse.Posteroanterior chest radiogram showed biapical large cavities (Fig. 1, arrows), as well as reticulo-nodular opacities, volume loss in left lung and pleural thickening. Computed tomography (Fig. 2) highlighted the thick-walled cavities and their bronchial communication (arrow) suggesting endobronchial spread of an infectious process. 1On the basis of these findings the diagnosis of postprimary tuberculosis was supposed and confirmed with positive smear and culture results. Human immunodeficiency virus testing was negative.A successful treatment protocol of isoniazid, rifampicin, pyrazinamide and ethambutol was administered.Despite a sustained minor reduction of the incidence of TB in developed countries, it is still challenging, even in the 21 st century mainly by HIV co-infection, substance abuse and emergence of drug-resistant tuberculosis.
