- FIGURE 1.
A 54-y-old woman with differentiated papillary thyroid carcinoma (pT2 N1a [6/21] Mx) after total thyroidectomy and lymph node dissection of centrocervical and left lateral compartment. (A) Planar scintigraphy shows two 131I-avid foci interpreted as thyroid remnant. (B) SPECT/CT (left column) and CT (right column) demonstrate that these foci correspond to LNMs in superior mediastinum (level VII)—shown here for right focus.
- FIGURE 2.
A 30-y-old woman with differentiated papillary thyroid carcinoma (pT2 N0 [0/10] Mx) after total thyroidectomy and lymph node dissection of centrocervical compartment. (A) Planar scintigraphy shows large 131I-avid foci interpreted as thyroid remnant and indeterminate. (B) SPECT/CT fusion images (left column) and CT (right column) demonstrate 1 focus corresponding to LNM in level II. (C) SPECT/CT (left column) and CT (right column) demonstrate 1 focus corresponding to LNM in level III.
- FIGURE 3.
A 43-y-old woman with differentiated papillary thyroid carcinoma (pT1 N0 [0/7] Mx) after total thyroidectomy and lymph node dissection of centrocervical compartment. (A) Planar scintigraphy shows 131I-avid foci interpreted as LNMs (arrows) and thyroid remnant. (B) SPECT/CT fusion images (left column) and CT (right column) demonstrate that these foci correspond to LNMs in level II and level IV—shown here for lower focus.

Imaging results in patients classified as N0 (A) or Nx (B) by histopathology. “Nx” denotes classification as indeterminate.
