Color-Doppler US was performed on 20 patients with sub-clinic hypothyroidism which had been confirmed by laboratory tests. In all cases, color-Doppler US showed increased parenchymal flow, whose semiology was similar to the one known as "thyroid inferno" and currently associated, in the literature, with diffuse hyperfunction conditions. Quantitative measurements yielded no further element for differential diagnosis, while showing high flow speeds which were similar to those in hyperfunction. On the basis of consequent physiopathologic considerations, hypervascularization, as observed in hypothyroidism, is likely to be referred to the hypertrophic action of TSH, which was reported as high in all patients. In conclusion, the color-Doppler "thyroid inferno" pattern, which has been to date considered as specific of thyroid hyperfunction, has lost part of its diagnostic specificity, and further investigation--e.g. hormonal titers, scintigraphy--is needed for an unquestionable diagnosis to be made.
