Excision of a centrally based ventral intradural extramedullary tumor of the cervical spine through a direct posterior approach

Abstract This 3-dimensional operative video illustrates resection of 2 cervical spine schwannomas in a 19-yr-old female with neurofibromatosis type 2. The patient presented with lower extremity hyperreflexity and hypertonicity. Magnetic resonance imaging (MRI) demonstrated 2 contrast-enhancing intradural extramedullary cervical spine lesions causing spinal cord compression at C4 and C5. The patient underwent a posterior cervical laminoplasty with a midline dural opening for tumor resection. Curvilinear spine cord compression is demonstrated in the operative video. After meticulous dissection, the tumors were resected without complication. The dural closure was performed in watertight fashion followed by laminoplasty using osteoplastic titanium miniplates and screws. Postoperative MRI demonstrated gross total resection with excellent decompression of the spinal cord. The postoperative course was uneventful. The natural history of this disease, treatment options, and potential complications are discussed.

ABSTRACT A 7 yr old female spayed Yorkshire terrier was referred to the author's institute for a 5 mo history of recurrent cervical spinal pain. Neurologic examination did not reveal any deficits. Hematologic and serum analyses were within normal limits. Thoracic radiographs that incorporated the cervical spine did not show structural abnormalities. Magnetic resonance imaging of the cervical spine demonstrated a contrast enhancing, intradural extramedullary lesion at the level of the C2 vertebra. Hemilaminectomy was performed, during which a long, narrow nematode was visualized upon opening of the dura mater. The parasite was alive when removed during surgery, and the dog recovered with complete resolution of symptoms. The parasite was submitted and confirmed as a male adult Dirofilaria immitis. This is a novel case of an intradural D. immitis infection in the dog with a magnetic resonance imaging description of spinal D. immitis.

✓ A case is reported of a 45-year-old man who developed quadriplegia following a trivial motor-vehicle accident. Investigation including computerized tomography (CT) of the cervical spine revealed a large calcified lesion displacing the spinal cord and nerve roots, which proved to be a tuberculoma. The case is unusual in regard to the age of the patient, the size, location, and nature of the lesion, the mode of presentation, and the delineation of the lesion by CT scanning.
