case_images: A) and colon activity (white arrow in Figure 1 A) were seen. A diagnostic scan was performed after withholding thyroxin therapy for four weeks on follow-up two years after the therapy.
case_images: Anterior and Posterior Whole-body Scan Images on Follow-up Scan After Two Years of I-131 Therapy. A and B show intense accumulation of I-131 in left humerus mimicking metastatic disease. There was no uptake in thyroid bed demonstrating successful ablation of the remnant. C, Anterior and D, Posterior show that whole-body scan images were normal after having a bath and removing head scarf. There was physiological activity in the bowel and stomach in both scans.

case_images: Tg levels were 115 micro-IU/mL and > 0.2 ng/mL, respectively when the diagnostic scan was acquired. The diagnostic whole-body scan was performed 48 hours after administration of 185 MBq I-131 and showed accumulation of radioiodine in her left humerus mimicking metastatic disease (Figure 2 A and 2 B). There was no evidence of metastatic disease after 72 hours (Figure 2 C and 2 D).

case_images: Tg levels were 100 micro-IU/mL and < 0.1 ng/mL, respectively when the diagnostic scan was acquired. The diagnostic whole-body scan was acquired 48 hours after administration of 185 MBq I-131 and showed accumulation of radioiodine in his right shoulder mimicking metastatic disease (white arrows in Figures 3A and 3C) and intense bowel activity (black arrows in Figures 3A and 3B). There was no evidence of metastatic disease after self-cleaning after 72 hours (white arrow in Figure 3 D).

case_images: Anterior Neck Spot View. Uptake in thyroid bed is demonstrated with white arrows. Additionally, focal accumulation of radioiodine is seen in right maxillary region (black arrow) that belonged to a dental inflamation. See physiological nasal activity.

case_images: Diagnostic radioiodine scan was performed after withholding thyroxin therapy with a serum TSH level of > 150 micro-IU/mL and serum Tg level of < 0.2 ng/mL and demonstrated a focal accumulation of radioiodine in her right maxillary region belonged to a dental inflamation and physiological nasal radioiodine activity (Figure 4).

case_images: Anterior Neck Spot View. A, Uptake inferior to left thyroid bed that belonged to oesophageal activity is shown with white arrows. B, Uptake is cleaned with a drink of water.

case_images: Diagnostic radioiodine scan was performed after withholding thyroxin therapy with a serum TSH level of > 30 micro-IU/mL and serum Tg level of < 0.2 ng/mL and demonstrated a focal accumulation of radioiodine belonged to oesophageal activity (Figure 5A). After drinking water there was not any activity (Figure 5B).
