Cervical Intramedullary Schwannoma Research Articles

Upper cervical intramedullary schwannoma of the spinal cord presenting with myelopathy: illustrative case.

Intramedullary schwannomas account for 1.1% of all spinal schwannomas. Preoperative diagnosis is best accomplished by thoroughly evaluating clinical and radiological characteristics, accompanied by a high index of suspicion. The authors report a case of C2-3 intramedullary schwannoma in a young male who presented with neck pain and vertigo. The current literature is also reviewed. The authors reviewed the data of a young male with a 2-month history of neck pain and vertigo. Magnetic resonance imaging of the brain and cervical spine showed an intramedullary mass at C2-3 with a syrinx extending into the cervicomedullary junction. Laminectomy, myelotomy, and microsurgical excision of the mass under intraoperative neurological monitoring (IONM) were done. Postoperative pathology reported the specimen as a schwannoma. Gross-total resection of a schwannoma using IONM is the treatment of choice because of the lesion's benign nature, a better prognosis, and defined cleavage plane. Schwannomas should be included in the differential diagnosis of intramedullary spinal tumors. Because of its progressive nature, early surgery is recommended in symptomatic patients.

Cervical Intramedullary Schwannoma with Syrinx: Case Report and Review of the Literature

AbstractSchwannoma is a nerve sheath tumor originating from the Schwann cell. It is benign in nature and it arises from anywhere where Schwann cells can be found. It is rarely found in the parenchyma of the spinal cord. Intramedullary schwannomas (or neurilemmomas) without evidence of neurofibromatosis are rare spinal cord tumors. Intramedullary schwannoma was first reported in 1932 by Penfield. Our patient presented with neck pain, gradually worsening, weakness in the right upper and lower limbs, numbness in both shoulders, and a decrease in the grasping strength of both hands over a 4-year period. A magnetic resonance imaging of the spine showed a heterogeneously enhancing mass in the cervical spinal cord extending from the C2 to T1 levels with associated hemorrhagic changes. Histologically, the tumor was found to be composed of bland spindle cells with blunt-ended and sometimes wavy nuclei admixed with hyalinized vasculature. Surrounding reactive spinal cord parenchyma with frequent Rosenthal fibers was also observed. Focal Verocay bodies were evident, and with immunohistochemistry, there was diffuse and strong positivity for S100, which is confirmatory for the diagnosis of schwannoma. We report a case of cervical intramedullary schwannoma presented with syringobulbia in a young adult.

Surgical Resection of a Cervical Intramedullary Schwannoma: A Case Report and Literature Review

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.

Surgical resection of a cervical intramedullary schwannoma:A case report and literature review

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.

Intramedullary schwannoma of the cervical spinal cord

Summary Intramedullary spinal schwannoma is rare. Here, we report the case of a patient with solitary cervical intramedullary schwannoma that was detected by magnetic resonance imaging (MRI) and treated with total surgical resection. We have also reviewed similar cases reported in the literature. Our patient was a 44-year-old male tennis coach who presented with clumsiness, numbness, and weakness in all four limbs for 2 years. He exhibited Hoffman's sign and Lhermitte's sign, and showed sensory impairment below the C4 level and increased deep tendon reflexes; the muscle power of all four limbs was grade 4. MRI showed an intramedullary lesion with homogeneous enhancement at the C5–C6 level, approximately 3.6 cm in its greatest diameter. He underwent total resection of the tumor. Histopathological findings were consistent with the diagnosis of a benign schwannoma. The postoperative course was uneventful, and the patient was discharged without any change in his neurological status, apart from improvement in the strength of both his upper limbs. Intramedullary spinal schwannoma, although rare, is a benign tumor and, unlike intramedullary ependymoma and astrocytoma, can be cured by surgical treatment. Gross total resection can be achieved with minimal risks and a good clinical outcome.

Intramedullary Spinal Schwannoma: Case Report and Review of Preoperative Magnetic Resonance Imaging Features

Intramedullary schwannomas are rare spinal cord tumours. Correct preoperative diagnosis is essential for proper surgical planning and complete resection. We present a case of cervical intramedullary schwannoma followed by discussion on its preoperative magnetic resonance imaging features and review of the literature.

Cystic cervical intramedullary schwannoma with syringomyelia

We report a case of cervical intramedullary cystic schwannoma associated with segmental syrinx in a young adult without evidence of neurofibromatosis. The relevant literature is reviewed.

Solitary cervical intra- and extramedullary schwannoma

A case of solitary cervical intramedullary schwannoma with an extramedullary extension is reported. This case demonstrates the difficulty of radiologic diagnosis of these tumours and the necessity for pre-treatment biopsy.

Chiari type i malformation with an associated Intramedullary schwannoma

A case of Chiari type I malformation associated with a cervical intramedullary schwannoma is presented. A review of the literature concerning intramedullary schwannomas revealed their most frequent location to be in the cervical region. Their optimal treatment seems to be total removal as early in the course as is feasible. Emphasis is given to the need for actual demonstration of the cystic nature of the swollen spinal cord when dealing with Chiari type I malformation.
