Whole-body scintigraphy before (1A) and 4 days after (1B) therapeutic dose of I-131. Uptake in axillae is suspected in the pre-dose scan but is evident in the post-dose scan. Note uptake also in the inguinal regions

No other definite uptake was seen besides a very faint dubious higher concentration in both axillary regions, which was disregarded (Figure 1A). At the routine post-therapeutic WBS done on February 6, in addition to the expected uptake in the cervical remnants, definite uptake in both axillary regions and even in tiny structures in the inguinal regions was seen (Figure 1B).
SPECT/CT 4 days after I-131 therapy. Beside radioiodine concentration in the surgical remnants of the thyroidectomy, significant uptake is detected in the axillary lymph nodes, mainly in the left axillat axilla

At least one enlarged lymph node in the left axilla could be precisely identified (Figure 2).

In January 24, 2012, leukocyte count was 8,590/mm3 (100%) and lymphocytes were 3,800/mm3 (44%), showing a small rise in the relative count beyond the normal upper limit of 40% (Table 1, Figure 3).
Computed tomography before (4A) and 9 weeks after (4B) I-131 therapy. Note the marked reduction of lymph nodes in the left axilla
