Issue Date
We evaluated CT findings of bronchial carcinoid and accuracy of preoperative pathological diagnosis according to two subtypes. The subjects were 10 cases(typical;5, atypical;5), confirmed by surgery and tissue pathology. Sputum cytology(n=10), percutaneous aspiration(n=1) and bronchoscopic biopsy (n=8) were performed, preoperatively. The CT findings were analysed according to two subtypes. Typical carcinoid shows central location in all, and bronchial lumens just proximal to tumor were widened in two, whereas atypical carcinoid presented as peripheral leison in two. Among central atypical carcinoid, two cases showed flat meniscus appearance of lumen. Remaining one showed diffuse wall thickening. Intratumoral low density by necrosis was noted in one. Both subtypes show contrast enhancement. For preoperative diagnosis, sputum cytology & percutaneous aspiration were not conclusive at all. As for bronchoscopic biopsy, only 3 cases were accurately diagnosed as typical carcinoid. Typical carcinoid presented as endobronchial mass in all, whereas atypical carcinoid presented in various appearance. In all atypical & some typical carcinoid were misdiagnosed as primary lung cancer, preoperatively. However, in typical carcinoid, conservative surgery was possible. In conclusion, if there is discrepancy between CT findings & preoperative pathological diagnosis, full understanding of CT findings of bronchial carcinoid is imperative to choose appropriate surgical modality.
