title: Abnormal Tl-201 limb scan due to unilateral tremor.
abstract: A abnormal intra- and interextremity distribution pattern on Tl-201 was observed on the limb scan of a patient with a unilateral tremor. This is ascribed to the increased blood flow in the muscles responsible for the tremor. The suggestion is made that the existence of tremor should be considered as a possible explanation for unexpected abnormalities on Tl-201 limb scintigrams.
