4. The 18FDG-PET scan shows only mild tracer utilization in the right apical pulmonary nodule
The 18FDG-PET scan shows only mild focal tracer accumulation in the right upper lobe nodule, but some moderate tracer activity is also noted in the immediately adjacent pleura. The standard uptake value in the nodule itself was 2.3, with the immediate adjacent pleural activity reaching a standard uptake value of 3.2. No other sites of tracer accumulation were noted on the study, and the study was technically adequate. When incorporating the presence of only faint FDG uptake within the nodule, the Mayo Clinic Malignancy Risk Prediction Model (https://www.mdcalc.com/solitary-pulmonary-nodule-spn-malignancy-risk-score-mayo-clinic-model) estimates the probability of malignancy in this nodule to have decreased somewhat to 22.2%.
Several weeks later, the patient continued to complain of worsening chest and right upper quadrant pain which was now complicated by shortness of breath. Repeat frontal chest radiography (Figure 6) was performed.
