Reversible increased technetium-99m-HMPAO cerebral cortical activity: a scintigraphic reflection of luxuriant hyperperfusion.

A hemiparetic and aphasic patient, 3 days after acute traumatic transection of the left internal carotid artery requiring life-saving total embolic occlusion, revealed ipsilateral increased peripheral hemispheric 99mTc-HMPAO activity. Ten days postocclusion, HMPAO peripheral cortical flow normalized as hemiparesis and aphasia significantly cleared. The initial lateralized HMPAO hyperactivity pattern may reflect reactive hyperemia, a sign previously identified by contrast angiography and often associated with a better prognosis in evolving CVA. Evanescent peripheral cerebral hyperemia may represent beneficial cortical collateralization of the periinfarct area of a deeper lacunar (white matter) CVA.

Migratory osteolysis.

Migratory osteolysis is a recently recognized syndrome characterized by a migratory articular pain pattern of the lower extremities and associated radiographically with localized and reversible juxta-articular osteoporosis. Serial bone scans, both dynamic and static, appear to offer a new and more sensitive means for diagnosing and monitoring of this condition. The dynamic studies suggest that augmented osseous blood flow is responsible, at least in part, for increased radioactivity in clinically involved areas and presumably is mediating the osteoporotic process.
