McDougall listed 42 cases of physiologic and pathologic causes of abnormal distribution of radioiodine that can be misinterpreted for metastatic cancer in whole-body I-131 scans. The authors previously presented infected sebaceous cyst in the scalp as a cause of false-positive I-123 uptake. The authors use I-123 for routine thyroid scanning and for total- body search for metastatic thyroid cancer. The authors report one more false- positive result caused by oozing in the chest wall from the biopsy site for a pulmonary nodule.
