Excessive colon activity from antidiarrheal medication causing false-positive In-111 octreotide studies

111In-octreotide potential pitfall uptake of laparoscopic wedge liver biopsy

Somatostatin receptor scintigraphy may show benign In-octreotide uptake due to physiologic, inflammatory, or reactive processes. Awareness of these findings helps the imager to avoid pitfall interpretation of primary or secondary malignancies. To the list of previously reported potential false-positive findings of In-octreotide, the author adds a case of tracer uptake from laparoscopic wedge liver biopsy.
