ABSTRACT

RESUMEN La hemorragia alveolar difusa es un hallazgo clínico patológico, consecuencia de una lesión en la microcirculación pulmonar que se presenta con sintomatología inespecífica e incluso en pacientes asintomáticos. Se diferencian tres diagnósticos histopatológicos, siendo la capilaritis el más común y secundario a patologías autoinmunes. Se presenta el caso de un paciente, con hallazgo imagenológico y en lavado broncoalveolar, compatible con hemorragia alveolar difusa en quien se descartó como causa, enfermedades autoinmunes e infecciosas; durante la anamnesis, se identificó inicio reciente de montelukast, con relación temporal, respuesta a suspensión, cambio imagenológico y escalas de probabilidad de reacción adversa de Naranjo que apoya el diagnóstico.


ABSTRACT Diffuse alveolar hemorrhage is a pathological finding, defined as a consequence of a lesion in pulmonary microcirculation which occurs with non-specific symptoms, and sometimes it may show no symptoms. Three histopathological diagnoses are to be differentiated. The most common is capillary inflammation, which is secondary to autoimmune conditions. We present the case of a patient with image studies and bronchoalveolar lavage compatible with diffuse alveolar hemorrhage, in whom autoimmune and infectious causes were ruled out. The history of the patient indicated recent use of montelukast, being this time-related with the patient's clinical condition. The patient responded when the drug was withheld, image studies showed particular findings, and results in the Naranjo ADR scale supported the diagnosis.
