摘要 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.
Abstract: 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.

(b) Sagittal T2-weighted magnetic resonance image demonstrating a slightly hyperintense lesion, with swelling surrounding it. (c–e) Sagittal, coronal, and axial T1-weighted magnetic resonance images, with gadolinium contrast, demonstrating homogeneous enhancement of the tumor. The tumor appears as a solid mass, located to the right side of spinal cord, with clear margins. (f) Hematoxylin and eosin staining from the biopsy of the mass showing bipolar spindle cells with nuclei arranged in a palisade pattern (Hematoxylin & Eosin stain; magnification, ×100).
