See discussion.","Note 6 in the lung EOD scheme instructs us to assume that a pleural effusion is negative if a resection is done. Does this also apply to a pericardial effusion? For example, if a pericardial effusion is seen on CXR, and a subsequent lobectomy reveals only a localized tumor, should the effusion be ignored?","For cases diagnosed 1998-2003: Ignore pericardial effusion which is negative for tumor. Assume that a pericardial effusion is negative if a resection is done and the tumor is pathologically confirmed to be localized.","2003"
