[The structure of pseudocystic formations in the temporal lobe in focal epilepsy]

The material obtained in open operative interventions from 117 patients with focal (temporal) epilepsy was studied. In 58% of the observations rounded and oval-shaped cavities with distinct borders without any lining, i.e. pseudocystic structures were found. By morphological traits they could be related to cribllurs as there is a vessel in each cavity. All-level disturbance of intracerebral vessels and damage of blood-brain barrier together with hypoxia associated with it are probably the reason for criblir development. Pseudocystic structures that are not connected with the vessel lesion could be of another, sometimes inflammatory genesis. Thus, pseudocystic structures that unite in a network of channels connected with subarachnoidal space occur in temporal lobe in focal epilepsy in over half of cases.
