Summary A scintigraphic pattern consisting of peripheral pulmonary hypoperfusion is presented. This curvilinear or circumferential zone of decreased radio-activity is usually best recognized along the interlobar fissures. It is thought that the observed pattern results from numerous microemboli lodging in the small axial arteries at the lung periphery. In cases where multiple views, especially lateral projections, are obtained with the gamma camera, it is almost as common as the generally accepted discrete local defect.
