Extralobar sequestration located in the anterior mediastinum is a rare disease. Here we report a resected case of extralobar sequestration located in the anterior mediastinum.
A 16-year-old woman was admitted to our hospital with an abnormal shadow in the left middle lung field on chest X-ray film. Chest CT and MRI demonstrated a mass lesion in the left anterior mediastinum. Aortogram and pulmonary arteriogram showed no aberrant artery feeding the mass. Mediastinal tumor or pulmonary sequestration was suspected. Left thoracotomy was performed on August 15th, 1996. The mass exsisted between the anterior mediastinum and left upper lobe S3, and had a stalk connected to the hilum. The stalk contained branches of pulmonary artery, pulmonary vein, and bronchial artery. The resected mass consisted mainly of cystic lesions and had no connection with the bronchus, and was diagnosed pathologicaly as extralobar pulmonary sequestration.
