DISSEMINATED NOCARDIA-TRANSVALENSIS INFECTION RESEMBLING PULMONARY INFARCTION IN A LIVER-TRANSPLANT RECIPIENT

Infections due to Nocardia transvalensis are extremely rare: only four disseminated infections with this pathogen have been reported, three of which ended fatally. This is the first report of a liver transplant recipient with Nocardia transvalensis infection. The patient had disseminated infection with pulmonary involvement, which presented as pulmonary infarction. Despite a ten-day delay in the administration of correct therapy, he responded rapidly to trimethoprim-sulfamethoxazole. The pitfalls of differentiating nocardial infection from pulmonary thromboembolism in solid organ transplant recipients and the diagnostic considerations unique to liver transplant recipients are discussed.
