垂体瘤小于5毫米直径的,一般认为属于小垂体瘤范畴。摄头颅平片和常规体层片往往都不能发现它。近来,我院放射科采用薄层体层摄片,发现了一些其他方法不能诊断的小垂体瘤。我院神经外科为其中1例行垂体瘤摘除术,肿瘤直径仅4毫米大小。目前,国外手术大多采用经蝶窦凿开颅底的方法,少数用经颅切除鞍结节及蝶鞍前壁的方法切
Pituitary tumors less than 5 mm in diameter are generally considered to belong to the category of small pituitary tumors. Photographic skull slices and conventional body slices often cannot be found. Recently, the Department of Radiology of our hospital adopted a thin layer of radiography to find small pituitary tumors that cannot be diagnosed by other methods. Neurosurgery in our hospital is a case of pituitary adenoma removal, the tumor diameter is only 4 mm in size. At present, most foreign surgeries use transsphenoidal sinusoidal incision at the skull base, and a small number of methods for transcranial resection of saddle nodes and the anterior edge of the sella are used.
