    Abstract:
    Symptomatic pituitary metastases are uncommon and have been reported mainly in autopsy series. Although all types of malignancies can metastasize to the pituitary gland, a review of the literature has indicated that lung and breast carcinomas are the most frequent primary tumors while hepatocellular carcinoma metastasis has only recently been described. A 59-year-old man with abdominal pain and fever was admitted to our hospital. Hepatosplenomegaly was present without signs of ascites. Laboratory tests showed only abnormal hepatic biochemistry while the radiological studies revealed a solid mass occupying the left hepatic lobe. The patient underwent excision of the left hepatic lobe and was closely followed-up. Six months later he readmitted with headache and visual disturbances. MRI revealed a solid mass in the sella region pressing the optic chiasma. Transsphenoidal excision of the pituitary mass was followed and the histological examination of the tumor was compatible with hepatocellular carcinoma. Symptomatic pituitary metastases are uncommon and may be difficult to differentiate from pituitary adenomas. The present case emphasizes on the capricious nature of hepatocellular carcinoma and on the importance of the individualized therapeutic approach.
