ABSTRACT
Background:: Pulmonary cystic nodules are a relatively frequent finding in chest computed tomography (CT). There is a possible association between this finding and lung cancer. Aim: To report eight patients with malignant lung cystic lesions. Material and Methods: Retrospective analysis of images in a CT database from 2007 to 2015, looking for cystic lesions of the lung with wall thickening, whose pathological diagnosis was lung cancer. Results: We identified eight patients with cystic nodules aged 44 to 77 years, of which five were women. Six were active and two former smokers. The pathological diagnosis was adenocarcinoma in seven cases and squamous cell in one. The mean diameter of the cystic lesions was 11.5 mm. The mean diagnostic delay time was 871 days (range 0-1592). The main finding was a gradual thickening of the nodule walls. Conclusions: The presentation of lung cancer as cystic nodules is uncommon. In this series, the change in morphology due to a thickening of the walls with or without a diameter increase, was the clue for the diagnosis.

El tromboembolismo pulmonar (TEP) es un cuadro de lta morbimortalidad, siendo la principal fuente embolígena, la trombosis venosa profunda (TVP) de las extremidades inferiores (EE.II). Debido a esto, el estudio de un paciente con sospecha clínica de TEP, incluye la evaluación de las venas de las extremidades inferiores. La venografía por TAC ha demostrado ser muy útil en la evaluación de la TVP, existiendo numerosos trabajos que avalan su buena correlación con el Doppler venoso de extremidades inferiores. En nuestro estudio correlacionamos los hallazgos del doppler con los de la venografía por TAC en la detección de TVP de las extremidades inferiores en pacientes con sospecha clínica de TEP. Encontramos una muy buena correlación entre ambos métodos, con una sensibilidad del 100 por ciento y una especificidad del 88,9 por ciento para la venografía por TAC comparado con el doppler. Estos hallazgos que son compatibles con lo descrito en la literatura.
