title: [The methodological bases of topographic neuropathomorphology].
abstract: This paper describes the major features of topographic and anatomical studies of CNS structures, CSF circulation system, extracerebral structures and vertebral column. These methods include brain fixation, which is able to prevent post mortem brain deformation due to decalcification (even for block-preparations like "brain-skull base" or "posterior cerebral fossa-cervical spine"). The author also presents the following methods: spatial reconstruction of the brain and skull base subtracted from the series of slices of different thickness and various planes of transection; biopsy investigation of cerebral midline structures and CSF system in relation with skull base and convex structures; staged microdissection of tumors; filling of arterial and venous systems. All these modalities were used in examining the topographical features of craniopharyngiomas, hypophyseal adenomas, parasagittal and sagittal meningiomas, pineal tumors, VIII cranial nerve neurinomas, arachnoid cysts and in developing surgical approaches to the tumors of the third ventricle, skull base and foramen magna.
