ABSTRACT

La aspergilosis pulmonar es una infección micótica causada por el Aspergillus fumigatus, saprófito del esputo humano normal. Se estudiaron cinco casos de pacientes con aspergilosis, cuatro de ellos adultos, tres del sexo femenino y uno masculino, todos de presentación no invasiva, y uno, pediátrico, sexo masculino, del tipo invasiva. Fueron estudiados con radiología convencional, tomografía computada (TC) helicoidal, TC multislice y video cápsula endoscópica. Afecta 3:1 a los hombres en relación con las mujeres. Hay tres formas de presentación: a) invasiva: en los pacientes neutropénicos, donde predomina la afectación pulmonar, con diseminación a cerebro, corazón, riñón, tracto gastrointestinal, hígado, tiroides y bazo; tiene mal pronóstico y la mortalidad es muy elevada; b) semiinvasiva: compromete fundamentalmente a pacientes con patología pulmonar preexistente; c) no invasiva: afecta cavidades preexistentes, cavernas TBC ( tuberculosis) o quistes, donde coloniza el hongo, y se denomina aspergiloma o micetoma.


Pulmonary aspergillosis is a mycotic infection caused by the Aspergillus fumigatus, saprophyte of the normal human sputum. Five patients with non invasive aspergillosis were studied, of whom 4 were adults (3 women, 1 man) and one, pediatric, with invasive aspergillosis. All of them were studied by conventional X-ray, spiral CT, multislice CT and video capsule endoscopy. The presentation is predominant among men (3 to 1). There are three forms of presentation: a) invasive: in neutropenic patients it prevails the lung affectation; the brain, heart, kidney gastrointestinal tract, liver, thyroid and spleen spreading has a bad prognosis and mortality rate is very high; b) semiinvasive: it mainly compromises patients with pre-existing pulmonary pathology; c) non invasive: affects pre-existing cavities, TBC caverns or cysts where the fungus establishes; it is called aspergilloma or mycetoma.
