RT Journal A1 Reuler JB, Meier D T1 LEptomeningeal carcinomatosis with normal csf features JF Archives of Internal Medicine JO Archives of Internal Medicine YR 1979 FD February 1 VO 139 IS 2 SP 237 OP 238 DO 10.1001/archinte.1979.03630390089031 UL http://dx.doi.org/10.1001/archinte.1979.03630390089031 AB We report two cases of leptomeningeal carcinomatosis in which CSF-positive cytologic features were present but other CSF measurements were normal—a most unusual combination. In both cases, the results of the cytologic examination led to substantial therapeutic alterations. Cytologic examination of the CSF should be performed in any case with unexplained CNS symptoms or signs, regardless of the character of the CSF.(Arch Intern Med 139:237-238, 1979)
