UNEXPECTED ACCUMULATION OF TL-201 IN CEREBRAL INFARCTION

Three cases of cerebral infarct that unexpectedly showed accumulation of thallium-201 on single photon emission CT are presented here. In th e first case, infarction developed following removal of an intracerebr al hematoma. In the second case, infarction developed due to deep veno us thrombosis as demonstrated by angiography. In the third case, hemor rhagic infarction was diagnosed by the follow-up CT. The findings in t hese cases demonstrate that thallium-201 accumulation may occur in the liquefaction stage of cerebral infarction.
