Multiple primary intracranial tumors, or the presence of two or more primary intracranial tumors, are a rare clinical occurrence. The current study presents the case of a 28-year-old patient with concurrent left vestibular schwannoma, left cerebellar hemisphere dermoid cyst and craniovertebral junction malformation, specifically basilar invagination and Klippel-Feil syndrome. The patient exhibited symptoms of torticollis and recurrent headaches, with no apparent hearing loss. A far lateral approach was selected for surgical resection to address these complex conditions and achieve gross total resection in a single-stage surgery while preserving both facial and auditory nerve function. Successful gross total resection was achieved and the function of both nerves was effectively preserved. Of note, the coexistence of vestibular schwannoma and dermoid cyst in the same patient has not been documented in the existing literature. The present study provided a comprehensive account of the presentation and progression of this uncommon medical scenario. Furthermore, a surgical principle for the management of multiple primary intracranial tumors was proposed.
