    Abstract:
    OBJECTIVES: To evaluate the clinical manifestation and diagnostic characteristics of pulmonary sequestration. METHOD: By retrospective analysis. RESULTS: 21 cases of pulmonary sequestration, identified by surgicea-pathologically, were reported. Only 4 cases were correctly diagnosed before operation, the other 17 cases were misdiagnosed as cyst, benign tumor or bronchiectasis. 177 cases (including the cases of our own) consist: 146 cases of intralobular type and 31 cases of extra lobular type. In 21 cases of our series, the lesions were found predominantly in the left lower lobe (13), right lower lobe (5), right upper lobe (2), right middle lobe (1). The manifestation of chest X-ray were well defined mass-like density, or cystic shadow with fluid level. CONCLUSIONS: Imaging with ultrasound, CT scan and MRI has important value in establishing a definite diagnosis by showing the anomalous artery. However, retrograde aortography plays a decisive role for confirming the diagnosis.
