Figure 1. (A) Anterior and (B) posterior views of the 131I whole body scan showing an irregular pattern of 131I uptake in the lower right chest region. Point sources indicate the skull vertex, shoulder and iliac crest levels, respectively. (C) The right lateral projection of the chest region shows 131I activity is anterior but could not clearly differentiate between breast and lung metastasis.

Figure 2. (A) Anterior and (B) posterior projections of a later 131I whole body scan now show bilateral 131I uptake in the lower chest regions. (C) Right and (D) left lateral projections of the chest confirm the 131I activity is in the bilateral breast regions. Point sources indicate the skull vertex, shoulder and iliac crest levels, respectively.
