BACKGROUND: Brain metastases are one of the main causes of morbidity and mortality of patients with oncological disease. In non-small cell lung carcinoma (NSCLC), the risk of CNS secondary development is 30-50%. An unusual diagnostic and therapeutic problem is the finding of suspicious pituitary lesions. Obtaining a differential diagnosis relies on evaluating the clinical course of the disease (visual disturbances, diabetes insipidus (DI), weakness etc.), and performing endocrinological examinations and imaging analyses (CT, but mainly MRI). Sometimes, however, definitive resolution of the problem requires histological assessment of the tumor. CASE REPORT: A 65-year-old patient with a newly diagnosed metastatic lung adenocarcinoma was admitted to our department for a first cycle of chemotherapy consisting of cisplatin and navelbine. However, at the beginning of hospitalization, the patient developed qualitative disturbances in consciousness and disorientation. Emergency CT of the CNS revealed a tumor of the pituitary gland, and a subsequent MRI showed intraseller and suprasellar masses making contact with the optic chiasma. An endocrinological examination revealed panhypopituitarism. Pituitary metastasis of NSCLC was confirmed by tumor histology using the trans-sphenoid approach. CONCLUSION: Lung and breast carcinomas are among the most common cancers to metastasize to the pituitary gland. The incidence of pituitary metastases is reported to be 0.4-28.1%. Clinically, they are mostly silent, but may manifest as endocrine disorders, such as DI, hypothyroidism, and hypocorticism, or as visual disturbances due to compression of the optic nerve. Management depends on the establishment of a correct diagnosis.

BACKGROUND: Pituitary metastases are a rare complication of generalized cancer. Metastases to the pituitary gland occur in only 1% of patients operated on for sellar tumor. The most common presenting symptom in patients with pituitary metastases is diabetes insipidus, whereas this is rare in those with pituitary adenoma. MATERIAL AND METHODS: This publication presents the cases of two patients with pituitary metastases and a systematic review of the literature. English-language publications related to pituitary metastases and published from 1957 to 2016 were identified using the PubMed database. RESULTS: A total of 131 publications containing information about 259 patients (121 female and 138 male; mean age, 57.3 years) were identified. The most often metastasized breast carcinoma (24.6%) and lung carcinoma (23.8%), followed by thyroid carcinoma (11.3%), renal cell carcinoma (7.8%), hepatocellular carcinoma (4.3%), colorectal carcinoma (3.5%), and malignant melanoma (3.5%). The most frequent initial symptoms were manifestations of diabetes insipidus (39.6%), anterior pituitary deficiency (44.9%), perimeter disorders (51.6%), headache (37.6%), cranial nerve palsy (33.5%), and pseudoprolactinemia (16.7%). Radiotherapy (67.8%) and surgical treatment (63.9%) were the most frequently used treatment. CONCLUSION: The average survival time from the onset of metastatic disease was 11.8 months. Surgical therapy alone or in combination with radiation therapy does not prolong survival, but alleviates symptoms and improves quality of life.Key words: pituitary metastasis - diabetes insipidus - hypopituitarism - transsphenoidal surgery The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.
