Pituitary hormone concentrations in cerebrospinal fluid in patients with prolactin and growth hormone-secreting tumors.
GH, PRL, LH, FSH and TSH were measured in serum and in cerebrospinal fluid (CSF) in 16 patients with chromophobe adenomas, in 8 with acromegaly and in 18 subjects with neurological diseases without endocrine troubles. Elevated mean GH and PRL levels in serum and in CSF were found in patients with chromophobe adenomas and with acromegaly. No constant correlation was observed between serum and CSF values. The highest hormonal levels in CSF were usually observed in adenomas with suprasellar extension, but this finding was inconstant. The determination of hormonal levels in CSF does not seem to supply any reliable information about the characteristics of pituitary tumors.
