[Intralobar pulmonary sequestration with high level of serum CEA; report of a case].
ABSTRACT We reported a case of intralobar pulmonary sequestration with a high level of the serum CEA. A 53-year-old woman whose chief complaint was cough was admitted to our hospital. Enhanced chest computed tomography (CT) revealed the mass in the left lower lung, lymph-nodes swelling, and the aberrant artery. Magnetic resonance angiography (MRA) conformed the aberrant artery from the descending aorta. The level of serum CEA elevated at 9.6 ng/ml. Left lower lobectomy was performed. A diagnosis of intralobar pulmonary sequestration (Pryce type II) was established in this case. Histopathologically, the peribronchial epithelial cells in pulmonary sequestration showed weak positive for anti-CEA monoclonal antibody. Postoperative course was uneventful and the serum CEA level was 3.5 ng/ml in the normal range at the postoperative 17th day.

ABSTRACT: A 74-year-old woman with rheumatoid arthritis was referred for a mass incidentally noted on chest radiograph. Chest CT scan showed cystic lesions in the right lower lobe. The lesion was evaluated as bronchiectasis, and she was followed up. Three years after the initial presentation, the appearance of the lesion had changed significantly and an elevated air-fluid level in the cystic structures was shown on chest CT scan. The preoperative serum progastrin-releasing peptide (proGRP) level was elevated (108.0 pg/ml; normal: <50 pg/ml). Histopathological specimen obtained by standard lower lobectomy confirmed that the lesion was an intralobar pulmonary sequestration. In the resected lobe, there was no malignant finding, but there were neuroendocrine tumorlet cells, which were positive for proGRP. One month after the resection, the serum proGRP level returned to normal. No pulmonary sequestration with high levels of proGRP has been reported, and this is the first case with elevated serum levels of proGRP.Internal Medicine 02/2008; 47(3):157-60. · 0.97 Impact Factor
