[Pulmonary alveolar proteinosis and crazy paving pattern in high resolution CT]. / Proteinosis alveolar pulmonar y patrón en empedrado ("crazy-paving") en tomografía computarizada de alta resolución.

We present a case of pulmonary alveolar proteinosis in a 27 year old male, in which high resolution computerised tomography shows a typical crazy paving pattern. This test led to a specific differential diagnosis, in spite of the lack of specificity in the clinical presentation. The bronchoalveolar wash was not conclusive and the definitive diagnosis was made with a transbronchial biopsy. We review the most characteristic aspects of this rare disease and of the crazy paving pattern in high resolution CT.

Proteinosis alveolar pulmonar y patrón en empedrado (“crazy-paving”) en tomografía computarizada de alta resolución / Pulmonary alveolar proteinosis and crazy paving pattern in high resolution CT

Se presenta un caso de proteinosis alveolar pulmonar en un varón de 27 años en el que la tomografía computarizada de alta resolución muestra un típico patrón “crazy-paving” o en empedrado, siendo esta prueba la que orienta hacia un diagnóstico diferencial concreto, a pesar de la inespecificidad de la presentación clínica. El lavado broncoalveolar no es concluyente y el diagnóstico definitivo se hace con biopsia transbronquial.Se revisan los aspectos más característicos de esta rara enfermedad y del patrón “crazy-paving” o en empedrado en la tomografía computarizada de alta resolución

[Silicosis]. / Silicosis.

Silicosis, which acquired great significance during the period of increase in mining and construction, continues to be a pathology with a high morbidity and mortality within pneumoconiosis. Exposure to silica produces pathological, clinical and radiological alterations that together with compatible personal antecedents suggests its diagnosis in a simple way. The associated complications as well as its differential diagnosis from other types of pneumopathy mean that a review of this entity is needed.

[Hypersensitivity Pneumonitis (extrinsic allergic alveolitis)]. / Neumonitis por hipersensibilidad (alveolitis alérgica extrínseca).

Farmer's lung was first described in 1932. We can define hypersensitivity pneumonitis as a pulmonary and systemic disease that is accompanied by dyspnoea and coughing; it is caused by an immunological type of inflammation of the alveolar walls and the terminal airways and it is secondary to the repeated inhalation of a variety of antigens by a susceptible host. It can be said that it is an underdiagnosed disease and only a high degree of clinical manifestations and a detailed history of exposure can lead to an early diagnosis and satisfactory treatment. A combination among clinical-radiological, functional, cytological or pathological findings leads in some cases to a diagnosis. Treatment is based on avoiding further exposure to the causal agent and in the more serious cases the administration of systemic corticoid treatment.

Neumonitis por hipersensibilidad (alveolitis alérgica extrínseca) / Hypersensitivity Pneumonitis (extrinsic allergic alveolitis)

El pulmón del granjero se describió por primeravez en 1932. Podemos definir la neumonitis por hipersensibilidadcomo una enfermedad pulmonar y sistémicaque cursa con disnea y tos, y que se produce porla inflamación de tipo inmunológico de las paredesalveolares y vías aéreas terminales y que es secundariaa la inhalación repetida de una variedad de antígenospor un huésped susceptible. Puede decirse que es unaenfermedad infradiagnosticada y sólo un alto grado desospecha clínica y una historia detallada de la exposiciónpueden llevar a un diagnóstico precoz y un tratamientosatisfactorio. Una combinación entre los hallazgosclínico-radiológicos, funcionales, citológicos o anatonomopatológicos,en algunos casos, nos llevarán aldiagnóstico
