摘　　要：We reported a rare case of a dialysis patient coincident pituitary prolactinoma with calcification. A 55-year-old woman who had undergone hemodialysis for 8 years was admitted to the nephrology unit because of headache, blurred vision, and hypotension. Physical examination was normal; endocrinological examination demonstrated elevated serum levels of prolactin （〉4240 mlU/L）, but other hormonal profiles, such as growth hormon, adrenocorticotropic hormone, thyroid stimulating hormone, free triiodothyronine, free thyroxine, follicle-stimulating hormone and luteinizing hormone, were absolutely or relatively lower. A cranial computed tomography （CT） suggested saddle area a high-density screenage with an anteroposterior diameter of 1.0 cm. A cerebral magnetic resonance scan confirmed the pituitary adenoma accompanied with calcification. Contrast-enhanced Tl-weighted images revealed a less enhancing tumor, 14 mm wide round lesion with a high intensity signal. It enlarges the sella turcica, but the optic chiasma is not displaced. We suggest that in the differential diagnosis of any hemodialysis patient with severe headache, hypotension, and visual disturbances, this syndrome should be considered as prompt pituitary adenoma.We reported a rare case of a dialysis patient coincident pituitary prolactinoma with calcification.
