Subdural empyema associated with an apparent regional hyperperfusion (luxury perfusion).
A patient with a subdural empyema demonstrated a late arterial "blush" during a 99mTc-pertechnetate cerebral dynamic flow study which "washed out" in the delayed images. Cerebral arteriography and subsequent autopsy documented inflammatory tissue surrounding the empyema, resulting in this scintigraphic pattern.
