title: Thrombocytopenic thrombotic purpura: severe clinic with no CT, minor MRI, but a SPECT correlate.
abstract: A 28-year-old woman with primarily therapy refractory TTP was followed neuroradiologically over 6 months. Despite pronounced neurological and neuropsychiatric symptoms including hemiparesis and aphasia she had unremarkable CT scans on two occasions. Three MRI exams showed no correlate for her neurological symptoms except a small petechial cortical hemorrhage in the right parietooccipital gyrus which may account for her TTP-related anxiety disorder. A cerebral HMPAO-SPECT showed long-standing right-sided hypoperfusion compatible with residual vasculature changes. The possible causes for the clinico-neuroradiological discrepancies are discussed in view of the literature.
