[A case of simultaneous medullary hemorrhage and hematomyelia].
We reported a case of simultaneous medullary hemorrhage and hematomyelia. A 93-year-old woman, who had hypertension, was admitted to our hospital because of headache, numbness and weakness of the left extremities, and somnolence. On admission, weakness and disturbance of tactile sensations were observed in the left extremities. Magnetic resonance imaging showed medullary hemorrhage and hematomyelia and these two lesions were separated. Medullary hemorrhage was at the left dorsal paramedian area within mid-lower medulla oblongata, and hematomyelia was at the left side of the gray matter from medullo-cervical junction to upper cervical cord. Five days later from admission, weakness occurred in the right lower extremity and also in the upper extremity. This process suggested that the main lesion of tetraparesis was medullo-cervical junction. Review of 16 cases of medullary hemorrhage demonstrated that frequent neurological signs were palatal weakness, nystagmus, and disturbance of pain and temperature sense. But our case showed only disturbance of tactile sensations. Review of 19 cases of hematomyelia demonstrated that frequent neurological signs were sensory disturbance, paralysis and localized pain. Our case showed only paralysis. The cause of simultaneous hemorrhage was considered arteriovenous malformation or simultaneous multiple hypertensive hemorrhages.
