False-negative CTs in astrocytomas

The value of repeat scanning

Department of Neurology (Drs. Wulff, Proffitt, and Ziegler), Kansas University School of Medicine, Kansas City, KS, and Ball Memorial Hospital (Dr. Panszi), Muncie, IN.

In three cases of supratentorial astrocytomas, initial CT with contrast revealed no abnormality. The interval between the first negative scan and subsequent positive scan was 6 to 20 weeks. The reason for the false-negative scans are obscure. In occasional cases other diagnostic tests, i.e., EEG, may give clues to the presence of the tumor.
