[Diagnosis and surgical treatment of pituitary chromophobe adenomas of the "embryonal" type].

Verified "embryonal" adenomas were studied in 24 patients. It is established that these tumors are characterized by considerable spreading beyond the sella turcica, frequent growth into the cavernous sinuses, and rich vascularization. Diencephalo-vascular symptoms predominate in the clinical picture. Neurosurgical diagnosis calls for a complex of auxiliary methods of examination. The possibilities for radical removal of pituitary "embryonal" adenomas are limited. Attempts to remove as much of the tumor as possible, however, are justified. This proves possible if the specific sequence of the main stages of the operation with the use of microsurgical techniques is observed.
