title: Unexpected accumulation of thallium-201 in cerebral infarction.
abstract: Three cases of cerebral infarct that unexpectedly showed accumulation of thallium-201 on single photon emission CT are presented here. In the first case, infarction developed following removal of an intracerebral hematoma. In the second case, infarction developed due to deep venous thrombosis as demonstrated by angiography. In the third case, hemorrhagic infarction was diagnosed by the follow-up CT. The findings in these cases demonstrate that thallium-201 accumulation may occur in the liquefaction stage of cerebral infarction.
