Summary Radiosurgery ( RS ) is a well‐established ablative therapy for trigeminal neuralgia ( TGN ). Successful RS requires the delivery of an extremely high dose of radiation to a small cisternal portion of the nerve, which lies amidst critical structures. This study describes the utility of CT ‐cisternogram in RS targeting for TGN . We report on patients with TGN who required CT‐cisternogram for target identification for C yber K nife ( CK ) RS at our institution between S eptember 2010 and A pril 2015. CT ‐cisternogram is a well‐tolerated procedure that adds useful information to RS planning. Illustrative cases with complex anatomy and MRI artifacts related to postoperative changes and T eflon implant are described. CT ‐cisternogram is a complementary imaging modality that is useful in some patients, for RS target delineation.
