Abstract:
We describe a patient with AIDS who presented with focal neurological symptoms, and who had contrast-enhancing brain lesions on MRI which demonstrated increased thallium-201 uptake on SPECT. These findings were consistent with lymphoma; however, brain biopsy established a diagnosis of progressive multifocal leukoencephalopathy (PML). To our knowledge, this is the first reported case of PML with increased thallium-201 uptake on brain SPECT.
