Journal of Thoracic Imaging: April 2003 - Volume 18 - Issue 2 - p 97-99

The authors report two cases of round atelectasis that showed increased accumulation of technetium (Tc) 99m depreotide on planar and single photon emission computed tomographic scintigraphy. It should be considered that round atelectasis is a potential nonmalignant cause for positive 99mTc depreotide scintigraphy.
