Abstract

Since 1970 to 1971, 3 cases of tumor of foramen magnum were experienced and treated surgically at neurosurgical department of N.M.C. so clinical manifestation of tumor of foramen magnum were analyzed and evaluated with our 3 case and 7 cases of Symonds which was reported in 1937. The sex ratio was equal. Age distribution was highest among the patients in 4th decade. Tumor were meningioma neurofibroma orderly. Initial symptoms was neck or suboccipital pain, chief complains at time of admission were tetraplegia and paresis of limbs. The most commonly involved cranial nerves were 11th and 12th. The pattern of the muscle weakness of limbs was counter clockwise or clockwise. Sensory disturbances was subjective pain and paresthesia of the ipsilateral upper limb to lesion in early stage and objective sensory loss later. There were always pyramidal tract signs and increased pressure and protein in CSF. The plain cervical spine showed no pathological findings but revealed space occupying lesion on Pantopaque cervical myelgraphy through lumbar puncture. During operation and postoperative period respiro-cardio-vascular function was carefully observed.
