ABSTRACT
Los meningoteliomas pulmonares son tumores raros que se manifiestan morfológicamente como nódulos de pequeño tamaño. Aparecen con mayor frecuencia en la sexta y en la séptima década de la vida, con predilección por el sexo femenino. Su etiología es desconocida y en el diagnóstico radiológico diferencial deben incluirse las enfermedades que cursan con un patrón nodular. Diversos autores han documentado una clara asociación, estadísticamente significativa, entre esta entidad y diversas enfermedades pulmonares, y la más frecuente es el adenocarcinoma de pulmón. Existen actualmente muy pocos casos radiológicos documentados en la literatura médica. Presentamos el caso de una paciente con antecedentes de carcinoma de mama y de recto metacrónicos. En el estudio de extensión de este último se evidenció un patrón micronodular pulmonar bilateral. Los hallazgos radiológicos se interpretaron inicialmente como metástasis y se alcanzó el diagnóstico definitivo de meningoteliomatosis mediante biopsia pulmonar (AU)
Pulmonary meningotheliomas are rare tumors that manifest as small nodules. They are most common in the sixth and seventh decades of life and are more common in women. Their cause is unknown and the imaging differential diagnosis should include other diseases that course with nodular patterns. Several authors have documented a statistically significant association between pulmonary meningotheliomatosis and diverse lung diseases, with adenocarcinoma of the lung being the most frequently associated disease. Very few cases of radiologically documented meningotheliomatosis have been reported. We present a case of a patient with a history of metachronous breast and rectal cancer. A micronodular pattern was observed in both lungs during CT examination to determine the extent of rectal cancer. The radiologic findings were initially interpreted as metastases and the definitive diagnosis of meningotheliomatosis was reached after lung biopsy (AU)

Tumour thrombosis of the inferior cava vein is usually associated with primary renal cell cancer. To our knowledge, this is the first case reported of adrenal metastasis of breast cancer extending into the inferior vena cava. There are few references in the literature documenting this extension with positron emission tomography (PET) and enhanced computed tomography (CT). The authors focus on the role of combined PET-CT imaging in the accurate detection of malignant thrombus (AU)
