A Case of Concurrent Schwannoma and Meningioma at the Same Cervical Level

Abstract

  Concurrent spinal tumors such as schwannomas and meningiomas are usually associated with neurofibromatosis type 2 (NF2). Here we report an extremely rare case of concurrent schwannoma and meningioma at the same cervical spinal level. This patient did not meet the diagnostic criteria for NF2. Because the surgical strategy for spinal schwannomas may differ if meningiomas are concurrently present, it is important to pay attention to preoperative imaging findings. Unlike in previous patients, however, it was difficult to diagnose the presence of two different tumors based on preoperative images of the present patient. Preoperative images and intraoperative findings must therefore be carefully assessed to determine whether spinal tumors extending into the intradural and extradural spaces consist of concurrent schwannomas and meningiomas.
