[Somatostatin analogs in the clinical management of pituitary neoplasms].

The medical approach to patients with secreting or clinically non-functioning pituitary adenoma as made considerable progress thanks to the use of new somatostatin analogs. They were first used to treat acromegaly in the mid 1980s and numerous studies have shown a reduction in GH concentration in over 90% of acromegalic patients. Good results were obtained using slow-release analog treatment also in TSH-secreting adenomas, whereas the therapeutic efficacy of these peptides in clinically non-functioning adenomas is still controversial. Treatment with somatostatin analogs improves symptoms, normalises hormone secretion and in some cases may induce a reduction in the volume of pituitary adenomas. Scintigraphy with octreotide may help to select patients who respond to this form of treatment.

Intracranial dissemination of an ACTH secreting pituitary neoplasm--a case report and review of the literature.

A 52-year-old woman developed recurrent hypercortisolism 3 yr after successful surgical treatment of Cushing's disease. At postmortem, eosinophilic pituitary tissue showing positive ACTH immunohistochemical staining was present in the frontal lobe and cerebellum but there was no tumor in the sella. In the absence of a pituitary tumor, extrasellar ACTH producing tissue could arise from seeding of the cerebrospinal fluid with tumor cells at the time of operation or from an atypical pituitary carcinoma. In this report we review the mechanisms of intracranial dissemination of pituitary tissue and ACTH-secreting pituitary carcinomas, including parasellar invasion, meningeal seeding, and cerebrospinal and hematogenous spread.
