“…Glazer et al (1982) reported five characteristic CT features of mediastinal thyroid: (1) anatomical continuity with a cervical thyroid, (2) focal calcification, (3) relatively high CT number, (4) rise in CT number with contrast enhancement and (5) prolonged enhancement after contrast administration. On the other hand, mediastinal involvement in recurrent thyroid carcinoma is reported to have a non-specific CT appearance, such as lymphadenopathy or chest wall invasion (Pearlberg et al 1989). In contrast, normal thymus has a bilobed, arrowhead-shaped cross-section at all ages and can be detected by residual flecks of thymic parenchyma within the gradually increasing amount of parenchymal fat (Moore etal.…”

Visualization of the thymus with therapeutic doses of radioiodine in patients with thyroid cancer

et al. 1993

Two cases of papillary carcinoma of the thyroid are presented in which whole-body scans following therapeutic doses of iodine-131 revealed intense anterior mediastinal uptake. In both cases, the mediastinal uptake was absent from scans obtained after removal of the entire thymus. Histologically, the resected thymus glands showed hyperplasia and contained neither thyroid tissue nor metastatic foci of thyroid carcinoma. We therefore concluded that anterior mediastinal uptake of radioiodine may be caused by hyperplasia of the thymus.
