Bronchial carcinoid tumors: assessment with CT of location and intratumoral calcification in 31 patients

Radiology. 1991 May;179(2):483-6. doi: 10.1148/radiology.179.2.2014296.

Abstract

Bronchial carcinoid tumors (BCT) have long been regarded as predominantly central and rarely calcified. The authors retrospectively reviewed computed tomographic (CT) findings in 31 patients (thin-section CT studies in 18) who were seen at their institution with the histopathologic diagnosis of BCT (27 typical, four atypical) during the years 1978-1989. Eighteen BCT (58%) were central and 13 (42%) peripheral, with peripheral defined as located more than 2 cm distal to the origin of the appropriate segmental bronchus. CT scans revealed varied patterns of calcification in seven (39%) of the 18 central BCT and in one (8%) of the 13 peripheral BCT (P less than .1); overall, CT scans revealed calcification in eight (26%) of the BCT. The eight calcified tumors were each of the typical histopathologic type. Peripheral BCT (42%) were nearly as common as central BCT (58%), and CT detection of calcification in BCT was not uncommon (39% of central lesions; 26%, overall).
