ABSTRACT

A radionuclide angiogram done with ^99mTc immediately after the onset of symptoms of a cerebrovascular accident revealed the expected findings of decreased flow on the affected side. However, a repeat study 11 days later showed markedly increased flow in the same area with pronounced uptake also seen on the early static images. By 23 days, the flow pattern and early static images had reverted to normal. This sequence appears to represent a radionuclide demonstration of the "luxury-perfusion syndrome" and supports the hypothesis that the occurrence of this syndrome in ischemic cerebrovascular disease is a transient, time-dependent phenomenon. Clinicians should be aware that this pattern of increased flow can be compatible with the diagnosis of stroke.
