Figure 1From: Selectively false-positive radionuclide scan in a patient with sarcoidosis and papillary thyroid cancer: a case report and review of the literatureCorresponding SPECT and fused SPECT/CT images showing concerning cervical lesions. SPECT coronal slice (left) and fused SPECT/CT image (right) demonstrating abnormal foci of accumulation of 99mTc04 − radioactive tracer in a lymph node of the left jugular chain, ipsilateral to the known thyroid tumor. [Dotted line (−−-) indicates submandibular gland; small dotted arrow indicates thyroid remnant; large arrow indicates the area of concern in the lateral jugular chain]. No appreciable 99mTc04 − uptake is observed in the superior mediastinum, where extensive nodal disease was identified on plain CT-Neck.Back to article page
