Mucoid impaction of the trachea simulating a tumor: a case report.
Mucoid impaction of the trachea simulating a tumor has been rarely reported. We report such a case tomographically presenting as a tumor in a 75-year-old woman with chronic obstructive pulmonary disease (COPD). A rapid change in the shape of tracheal shadow with sharp angle was also shown tomographically. It is suggested that a changing shadow in the trachea demonstrated by tomography may be of value in distinguishing mucoid impaction of the trachea from true neoplasm.
