Background: Intraneural ganglions are rather rare non - neoplasmatic tumors of peripheral nerves, their ethiology is unclear and their preferred localization is uncommon peroneal nerve. Reports on this subject in available literature are of casuistic character.
Case report: In this paper 3 surgically treated cases of the intraneural ganglion in the common peroneal nerve have been described. Authors attempt to establish the ethiopathogenesis of described tumors and present different operative techniques applied in certain cases depending on
intraoperative findings. Own observations are confronted with other authors experiences and results. In one case the result of treatment was very good and in one case no recovery was obtained.
Conclusions: Results of intraneural ganglions treatment are generally good. Poor results are obtained in cases where neurological deficit prior to surgery is big and intraoperatively the significant part of the nerve trunk appears to be damaged.
