This occurs at the border zone between major cerebral arteries. Its CT findings are characteristic as a wedge shaped low density appearing either in the superior frontal region (watershed between anterior and middle and posterior cerebral artery), and always involving the deep white matter onto the ventricle wall. Even though the CT feature is small, a patient, without exception, suffers from neurologic deficit. We studied four cases of a watershed infarction on X-ray CT and compared with 123I-IMP SPECT. DSA was also made to demonstrate an obstruction of an artery which was usually found at the more proximal segment then what we expected from the CT feature. The findings on the 123I-IMP SPECT were better predictable of neurologic symptoms and they were larger in extent than the CT findings.</p>","PeriodicalId":21520,"journal":{"name":"Rinsho hoshasen.

Ten patients were examined. Plain CT showed all tumors as hypodense mass. After injection of contrast material, they were enhanced in various fashions. The enhancement patterns were divided into four types. On enhancement CT, highly enhanced area in the tumor was consistent with hypercellular region or vascular rich area, whereas poorly stained area revealed hypocellular area, interstitial xanthomatous change or cystic degeneration. It is concluded that the inter-tumoral difference in special distribution of hyper- and hypocellular areas leads to the variety of enhancement pattern on CT images.</p>","PeriodicalId":21520,"journal":{"name":"Rinsho hoshasen.
