Carbamate poisoning: high resolution CT and pathologic findings

Carbamate insecticides are commonly used agricultural insecticides. The major cause of morbidity and mortality in acute carbamate poisoning is respiratory failure associated with pulmonary edema. Although carbamate poisoning is well recognized in the clinical literature, the findings of high resolution CT (HRCT) with carbamate have not been reported. We report the radiographic and HRCT findings of a patient with acute carbamate poisoning who had pathologically proven interstitial pneumonitis after resolution of initial pulmonary edema.
