FORAMEN MAGNUM SCHWANNOMA WITH AN UNUSUAL CLINICAL PRESENTATION - CASE-REPORT

This case report illustrates a patient with a unilateral localized epi dural schwannoma at C1-2 level, showing contralateral spinal cord symp toms and signs. The clinical presentation was compared with the neuror adiological examinations showing an epidural cord turner at the right C1 - C2 level. However, the neurological examination revealed contrala teral hemiparesis and ipsilateral hemihypoalgesia, indicating a contra lateral Brown-Sequard syndrome. We presumed with this slow growing tum or, contralateral cord involvement may result from counter pressure on the spinal cord, which may be generated by cord deviation and by freq uent neck rotation.
