Abstract

Tumors located in the craniocervical junction region are significantly challenging for surgical resection. We shared our experience of a meningioma at craniocervical junction resected through far lateral approach in a 68-year-old female. The patient presented with intermittent headache with discomfort in the neck and shoulders for 3 years without any positive signs. Magnetic resonance imaging (MRI) revealed a tumor of 3.6 cm × 3.0 cm × 2.5 cm lying at the ventral side of medulla oblongata, with T1 hypointensity, T2 hyperintensity, and a significant enhancement on T1-contrast image. The far lateral approach on the right side was planned to resect the tumor with a park-bench position. The patient underwent a standard craniotomy using a lazy S-shaped incision. The transposition of vertebral artery was performed carefully therein, followed by removal of part of the arches of atlas and axis. After exposure of the tumor, vertebral artery (VA) and posterior inferior cerebellar artery (PICA) adhesive to the lesion could be seen operatively. Truncating the supplying blood vessels of the tumor was taken as the first step, followed by resecting the tumor mass in a piecemeal manner. While preserving VA, PICA, posterior nerves, medulla oblongata, and cervical cord, gross-total resection was achieved under the careful operation. The patient tolerated the procedure well without any neurological deficits. Histological examination confirmed the tumor as a meningioma (World Health Organization [WHO] grade I). Postoperative MRI scan depicted complete resection of the tumor. The patient remained symptom free without any evidence of recurrence during the follow-up period of 1 year. Informed consent was obtained from the patient.
