Schwannomas are the most common type of spinal tumor, and they most commonly occur in intradural extramedullary locations. Intramedullary schwannomas of the central nervous system are very rare and are difficult to diagnose using preoperative imaging. Here, we report a rare, tiny cervical intramedullary schwannoma and review the literature regarding the clinical presentation, magnetic resonance imaging, pathology, and surgical experience associated with this rare tumor type.
