RESUMEN
Hypersensitivity reactions are characterized by inappropriate response of the immune system to an inciting antigen, which results in damage to various body tissues. Respiratory system can be involved as a part of hypersensitivity reaction by a myriad of conditions ranging from infective pathologies like tuberculosis to non-infective processes such as asthma, graft- versus host disease, sarcoidosis and vasculitic disorders. Recognition of specific imaging features in appropriate clinical setting helps in diagnosing these conditions. We present a review of mechanism of different types of hypersensitivity reactions; and imaging features of various such pathological conditions affecting the respiratory system.
