Transient crossed cerebellar diaschisis secondary to cerebral hyperperfusion following carotid endarterectomy.
نویسندگان
چکیده
We report a case of transient crossed cerebellar diaschisis secondary to cerebral hyperperfusion following carotid endarterectomy. The appearance of crossed cerebellar diaschisis under the presence of cerebral hyperperfusion may suggest the development of hyperperfusion syndrome.

Diaschisis is the depression of regional neuronal metabolism and cerebral blood flow (CBF) caused by dysfunction in an anatomically separate but functionally related neuronal region. It is most commonly recognized in association with stroke. Over 50% of patients with well-defined cerebral hemispheric lesions demonstrate crossed cerebellar diaschisis (CCD) as diminished CBF, oxygen consumption (...
متن کاملInterictal crossed cerebellar hyperperfusion on Tc-99m ECD SPECT.
Crossed cerebellar hyperperfusion (CCH) in epilepsy is a rare condition that is observed on ictal cerebral perfusion SPECT. The mechanism of CCH assumes that hyperperfusion in the epileptic foci of the unilateral supratentorium causes hyperperfusion secondary to the corticopontocerebellar pathway (CPCP)-mediated remote effect in the contralateral cerebellar hemisphere. This phenomenon is simila...

We report a girl with refractory partial seizures since 7 years of age, secondary to right frontal cortical dysplasia, who developed MRI and SPECT abnormalities in the contralateral hemicerebellar cortex. These became more marked, leading to left hemicerebellar atrophy. Crossed cerebellar diaschisis has been described mostly in hemispheric stroke and supratentorial tumours, but less often in ep...
متن کاملPreoperative Cerebral Oxygen Extraction Fraction Imaging Generated from 7T MR Quantitative Susceptibility Mapping Predicts Development of Cerebral Hyperperfusion following Carotid Endarterectomy.
BACKGROUND AND PURPOSE Preoperative hemodynamic impairment in the affected cerebral hemisphere is associated with the development of cerebral hyperperfusion following carotid endarterectomy. Cerebral oxygen extraction fraction images generated from 7T MR quantitative susceptibility mapping correlate with oxygen extraction fraction images on positron-emission tomography. The present study aimed ...

PURPOSE Cerebral hyperperfusion following carotid endarterectomy (CEA) occurs in patients with preoperative impairments in cerebral hemodynamics. The aim of the present study was to determine whether late images/early images on preoperative brain (123)I-iomazenil (IMZ) single-photon emission computed tomography (SPECT), which correlate with oxygen extraction fraction images on positron emission...
