ABSTRACT
PURPOSE: To evaluate the prevalence and degree of tracheal deviation seen on chest PA radiographs of thyroid lesions and to correlate these findings with their size, volume, pattern (localized or diffuse), location, and constitution . MATERIALS AND METHODS: Between May 1995 and July 1998, tracheal deviation seen on chest PA radiographs was retrospectively reviewed in 179 consecutive cases in which a thyroid lesion was seen on ultrasonography and/or CT of the thyroid. The criterion of tracheal deviation was more than 3mm. Thyroid lesions were classified as diffuse or localized according to their pattern; as central, marginal or borderline on the basis of their location, and as cystic, solid or mixed, depending on their constitution. RESULTS: Tracheal deviation was seen in 53 cases (29.6%, n=179); mean deviation was 5.6mm (3 -27 mm). Its incidence increased with lesion size (p0.05). The volume of the former type was measured and the incidence and degree of tracheal deviation was found to increase with lesion volume (p0.05). The most common location was borderline (n=30, 65.2 %), followed by central (n=12, 26.1%), and marginal (n=4, 8.7%). The most common type by constitution was solid (n=32, 69.6 %), followed by cystic (n=10, 21.7 %), and mixed type (n=4, 8.7 %) (p>0.05). CONCLUSION: Chest PA radiography revealed tracheal deviation of thyroid lesion in 53 cases (29.6 %). The incidence and degree of deviation increased with increasing size and volume of the lesion, but deviation did not correlate with the pattern (localized or diffuse), location or constitution of the lesion.
