title: Arteriographically confirmed focal defect in colloid spleen scan with no gross pathologic lession: case report.
abstract: A focal avascular defect in an enlarged spleen, clearly shown both by 99mTc-sulfur colloid scanning and by celiac angiography, could not be associated with any gross pathologic abnormality at splenectomy. Vascular lesions can probably produce focal defects on the scan in the absence of infarction.
