| ABSTRACT |
|
A case of basilar impression surgically treated in a female patient aged 22 years is presented. A myriad of abnormal neurologic findings were present that were secondary to compression of neural tissue by anormalous bony structure at craniovertebral junction. Metrizamide computerized tomography with coronal and sagittal reconstruction identified bony abnomalities and displacement of the surrounding neural structures. The surgical intervention for the treatment of the basilar impression consisted of ventral decompression by transoral odontoidectomy and of dorsal decompression by an enlargement of foramen magnum and by laminectomy of C1, followed by occipito-atlanto-axial bony fusion. |
