Las diferentes manifestaciones de la aspergilosis pulmonar. Hallazgos en tomografía computarizada multidetector / The different manifestations of pulmonary aspergillosis: Multidetector computed tomography findings

La aspergilosis pulmonar es una infección micótica causada la mayoría de las veces por la inhalación de esporas de Aspergillus fumigatus. Sin embargo, al hablar de aspergilosis, en realidad nos referimos a un abanico de manifestaciones clínicas y radiológicas que dependen directamente del estado del sistema inmune del paciente, de la existencia de enfermedad pulmonar previa y de la virulencia del organismo. Son 4 los tipos de aspergilosis pulmonar (aspergiloma, aspergilosis broncopulmonar alérgica, aspergilosis necrosante crónica y aspergilosis invasiva), cada uno con hallazgos radiológicos distintos. En este artículo revisamos el espectro de signos de la aspergilosis pulmonar en la tomografía computarizada multidetector y los correlacionamos con los síntomas y la respuesta inmune del paciente. Se abordarán asimismo los principales diagnósticos diferenciales (AU)

Pulmonary aspergillosis is a fungal infection usually caused by inhaling Aspergillus fumigatus spores. However, when we talk about aspergillosis, we normally refer to the spectrum of clinical and radiological findings that depend directly on the patient's immune status, on the prior existence of lung disease, and on the virulence of the infective organism. There are four types of pulmonary aspergillosis (aspergilloma, allergic bronchopulmonary aspergillosis, chronic necrotizing pulmonary aspergillosis, and invasive aspergillosis), and each type has its own distinct radiologic findings. We review the signs of pulmonary aspergillosis on multidetector computed tomography and we correlate them with patients’ symptoms and immune responses. Likewise, we discuss the differential diagnoses (AU)
