Noncardiogenic Pulmonary Congestion following Bone Marrow Transplantation

We report a 36-year-old female who developed acute pulmonary congestion as the first presenting sign of venoocclusive disease (VOD), complicating an otherwise successful bone marrow transplantation (BMT). Left ventricular function was normal by echocardiography. Conservative therapy included oxygen, Lasix, and low dose dopamine. Hepatic toxicity, the typical presenting feature of VOD, occurred in our patient 72 h after pulmonary congestion. VOD occurs in 20-50% of BMT patients and is the result of widespread endothelial damage as a result of chemoradiotherapy. The dominating clinical feature is liver toxicity. Pulmonary manifestations of VOD have not been described as presenting features, and in fact have been noted as rare and late sequelae of BMT. Therefore, in the setting of preserved left ventricular function, acute pulmonary congestion early after BMT may represent the onset of VOD.
