[Pulmonary sequestration associated with high levels of tumor markers in serum].
A 20-year-old woman was admitted to our hospital because of an abnormal shadow on a chest X-ray film. Laboratory tests done on admission showed high levels of tumor markers in serum. A computed-tomographic scan of the chest showed a multilocular cystic mass in the S10 of the right lung. Angiography revealed an abnormal artery that branched from the abdominal aorta, and therefore pulmonary sequestration was diagnosed. A right lower lobectomy was done. Analysis of fluid from the cyst revealed very high levels of CA19-9, CEA, and SLX. In an immunohistochemical study, epithelial cells of the cyst's walls were stained for CA19-9, CEA, and SLX. After the operation the levels of these tumor markers in serum were almost normal.
