Pulmonary Tumor Embolism Syndrome from Occult Colonic Adenocarcinoma

Abstract

Pulmonary tumor embolism syndrome is a rare phenomenon that can occur in patients who have an occult neoplasm that metastasizes. We describe a case of an elderly woman with an undiagnosed colon cancer who suffered from respiratory distress and compromised pulmonary blood flow from micro-metastasis in the pulmonary arteries.
