RESUMO
We present a patient without specific symptoms of vasculitis, with normal acute phase reactants, but with the pathological diagnosis of Takayasu' arteritis that was referred for a PET-CT with (18)F-FDG. Scan findings showed inflammatory activity in the vessel walls of the aorta and after the appropriate treatment, a second scan with (18)F-FDG, correctly assessed the therapeutic response. We discuss the contributions of PET-CT with (18)F-FDG in the management of this pathological entity.

Presentamos un caso de carcinoma adenoide quístico de tráquea demostrado mediante TC multidetector de 64 coronas, PET-TC, y correlación anatomopatológica, en un paciente con hemoptisis. En este artículo revisamos el diagnóstico diferencial de las lesiones traqueales únicas focales mediante tomografía computarizada (TC). Las técnicas de imagen permitieron el diagnóstico e infravaloraron la invasión de la pared traqueal en este caso, confi rmada con posterioridad mediante el estudio histológico
We present a case of adenoid cystic tracheal carcinoma detected by computerized tomography (64-MDCT) with cyto-histological correlation in a patient with hemoptysis. In this article we review the differential diagnosis of solitary focal tracheal lesions as they appear in computerized tomography (CT). In this case, image methods suggested the diagnosis but underestimated the tracheal wall invasion, which was established by histologycal examination of the resected tumor
