title: [Cervical spine osteochondroma presenting with torticollis and hemiparesis].
abstract: Osteochondromas are slow-growing benign bone tumors that are located frequently in the long bones. Approximately 1-4% of them occur in the spine. Solitary spinal osteochondromas may produce a wide variety of symptoms depending on their location and relationship to associated structures. We report a case of a 74-year old woman who was admitted to our hospital with complaints of progressive left hemibody weakness and cervicalgia. Neurological examination disclosed mild left-sided hemiparesis and left torticollis. Computed tomography and magnetic resonance imaging of the cervical spine revealed an expansive lesion affecting the left C3-C4 facet joint. The patient underwent a posterior C3 and C4 hemilaminectomy, complete excision of the lesion and instrumented posterior cervical fixation. Histological examination confirmed the diagnosis of osteochondroma. After surgery her symptoms improved progressively with no neurological sequels.
