The is a case report of the metastatic adenocarcinoma in the pituitary gland, of which the primary site is not identified. The predilection of metastatic carcinoma for the posterior hypophysis may be due to the fact that the neural protion has a blood supply directly from the systemic circulation, while the anterior lobe does not. The clinical manifestations are polyuria, polydipsia, indicating insufficiency in the posterior lobe of the pituitary, but the function of the anterior pituitary gland is preserved, The clinical diagnosis has been made by C.T. scan of brain, but it is difficult to differentiate from the pituitary tumor. the diagnosis was confirmed by surgical biopsy of the pituitary gland and it revealed the metastatic adenocarcinoma from unknown site.
