Abstract:
The authors report 47 cases of substernal goiters operated between 1971 and 1990. Forty-five patients had mediastinal-cervical-goiters (g.c.m.) and 2 had ectopic goiter (g.e.). Cervicotomy was performed in the 45 g.c.m., in 3 cases associated with sternal "split". The g.e. were treated with thoracotomy. Computed Tomography (TC) has been performed since 1984 in 26 patients; Magnetic Resonance (RM) since 1987 in 6 patients. The diagnostic accuracy for TC was 84.6% and 100% for MR on anatomical-topographic-definition, and 80.8% and 83.3% for presumptive diagnosis of nature, respectively. Considering the high diagnostic accuracy, the possibility to reconstruct the images in sagittal and coronal planes, the RM seems to be the elective diagnostic procedure for all substernal goiters.
