Diencephalic syndrome of emaciation (Russell's syndrome). Long-term survival

Abstract

Three cases of diencephalic syndrome are reported. Two of them, which have been observed postoperatively for more than 7 years, showed typical clinical and endocrinologic features at the time of their first admission, but showed mass signs uncharacteristic of diencephalic syndrome after recurrence of the tumor. Recent data showed a normal baseline for plasma growth hormone but abnormalities in provocation tests. The significance of age in the manifestation of the syndrome is briefly discussed, especially in relation to the tendency toward normalization in the growth hormone level at a later age.
