Objectives. To evaluate tomographic changes in pulmonary tuberculosis (TB), degree of agreement among three radiologists regarding tomographic diagnoses, and sequelae following treatment. Methods. Cross-sectional and descriptive study of 74 TB patients confirmed by sputum culture and chest computed tomography before (CT1) and 6 months after (CT2) drug therapy. Results were performed by three radiologists blinded to clinical and laboratory results. Results. Main findings in CT1 included nodules indicating the presence of a tree-in-bud pattern in 93% of cases, ill-defined nodules in 84% of cases, consolidation in 77% of cases, architectural distortion in 71% of cases, cavitary lesions in 62% of cases, and ground glass opacities in 37% of cases. Airway involvement, characterized by increased thickness and dilatation of the bronchial walls, occurred in 93% of cases. Pleural involvement occurred in 54%. There was an agreement on active TB among the three radiologists in 85% of cases. The results in CT2 indicated the presence of architectural distortion in 91% of cases and cylindrical bronchiectasis in 86%. Conclusions. The study established a tomographic pattern for diagnosis of active TB characterized by the presence of airway nodules, consolidation, architectural distortion, and cavitary lesions, and an almost complete degree of agreement (Kappa) was observed among the radiologists (0.85). CT after treatment assists in defining the cure.

A dermatomiosite é uma miopatia inflamatória que cursa com manifestações cutâneas. No adulto acima de 50 anos, pode estar associada a neoplasias malignas, comportando-se como um grande sinalizador de malignidade. OBJETIVO: Demonstrar essa associação com aspectos peculiares: dermatomiosite de apresentação atípica paralela a dois tumores sincrônicos, em geral, não relacionados àquela. RELATO DO CASO: Descrevemos o caso de um paciente do gênero masculino de 72 anos, que desenvolveu dermatomiosite, inicialmente apenas com quadro cutâneo clássico, evoluindo com lesões vesiculobolhosas, e, meses após, com miopatia. Após extensa investigação, foi localizado um adenocarcinoma de próstata. Houve remissão da doença após tratamento do câncer e administração de glicocorticoide. Durante a retirada gradual do glicocorticoide, ocorreu reativação da dermatomiosite, sendo reiniciadas investigações, que revelaram a presença de carcinoma escamoso de língua. Tratada esta neoplasia, houve remissão completa, mesmo após a retirada total do corticoide. CONCLUSÃO: Trata-se de um caso raro por envolver as formas menos usuais de apresentação da dermatomiosite, tanto com relação ao quadro cutaneomuscular, quanto à sua associação a tumores de próstata e língua (tumores nunca antes relatados juntos). Este caso demonstra a importância da investigação minuciosa em busca de neoplasias na abordagem desses pacientes.Dermatomyositis is an inflammatory myopathy with skin manifestations. In the adult over the age of 50 years, it can be associated with malignant neoplasias, being, thus, a signal of malignancy. OBJECTIVE: To show the association of dermatomyositis of atypical presentation with two synchronous tumors, usually not related to that. CASE REPORT: We report the case of a 72-year-old male, who developed dermatomyositis, initially with only classic skin findings, which progressed to vesiculobullous lesions, and, months later, to myopathy. After extensive investigation, prostate adenocarcinoma was diagnosed. After treatment of the cancer and administration of glucocorticoid, the disease went into remission. During gradual glucocorticoid withdrawal, dermatomyositis recurred, and the new investigation revealed the presence of squamous cell carcinoma of the tongue. After treating this neoplasia, complete remission occurred, even after total corticoid withdrawal. CONCLUSION: This is a rare case involving less usual dermatomyositis presentation forms, relating to the cutaneous-muscle findings and the association with prostate and tongue tumors (tumors never reported together). This case demonstrates the importance of a careful investigation, searching for neoplasias, when approaching such patients.
