title: Sonography and scintigraphy are necessary in diagnostics of cystic thyroid lesions.
abstract: Thyroid sonography in an otherwise asymptomatic 50-year-old woman revealed a mainly cystic lesion within the right thyroid lobe. Thyroid (99)Tc scan showed an enhanced uptake over the right thyroid lobe with suppressed activity over the remaining thyroid tissue. Following aspiration of 6 ml of cyst fluid, a solid lesion became apparent in the location of the original cyst corresponding to the scintigraphically detected autonomous adenoma. This case report emphasizes that ultrasonography and scintigraphy are complementary methods and should be used as such in the primary evaluation of thyroid nodules.
