  • The Diagnostic Value of Multi-slice Spiral CT for Bronchial Mucoid Impaction in Early Central-type Carcinoma of Lung

    ObjectiveTo discuss the diagnostic value of multi-slice spiral CT for bronchial mucoid impaction in early central-type carcinoma of lung. MethodsWe used multi-planar reformat, maximum intensity projection and minimum intensity projection to observe the characteristics of 15 patients with bronchial mucoid impaction in early central-type carcinoma of lung treated between March 2010 and October 2013. The characteristics included location, shape and enhanced performance of the tumor and the bronchial mucoid impaction. All the cases were confi rmed by operation or pathology. ResultsAmong the 15 cases, 12 were squamous cell carcinoma and 3 adenocarcinoma; 8 occurred on the right and 7 on the left. All the tumors showed equal density and were enhanced moderately. Bronchial mucoid impaction showed low density, no enhancement, accompanied bronchiectasis and occurred in bronchi which were far from the tumor, and there were 9 cases of strip, 5 of fabrication, and 1 of nodositas or cystic carcinoma. ConclusionThe location and shape of tumor and bronchial mucoid impaction are displayed clearly by multi-slice spiral CT and enhancement scanning can differentiate tumor from bronchial mucoid impaction. Multi-slice spiral CT has important diagnostic value in bronchial mucoid impaction of primary lung cancer in its early stage.

  • The CT Characteristics of Pleural Lung Cancer and Misdiagnosis Analysis

    ObjectiveTo discuss the CT characteristics of pleural lung cancer, and analyze the reason for misdiagnosis. MethodsThe CT data of 8 patients with pleural lung cancer confirmed by postoperative pathology and treated in Renshou People's Hospital and Fist Affiliated Hospital of Chongqing Medical University between January 2010 and December 2013 were retrospectively analyzed. ResultsAmong the 8 cases of pleural lung cancer, 6 occurred on the left and 2 on the right; there were 3 nodular and 5 irregular masses; 6 had uniform density and 2 had irregular focus and relatively lower density; 4 had osteolytic destruction of adjacent ribs; 6 had pleural effusion; and 5 had mediastinal lymph nodes enlargement, in which 1 had multiple lymph node metastasis of left lung hilum, left supraclavicular region and left axillary. All the 8 cases were enhanced moderately. ConclusionPleural lung cancer has certain featured manifestations on CT. Analyzing the features carefully, considering clinical symptoms, and cytological examination of hydrothorax can reduce the incidence of misdiagnosis.
