子宫内膜异位症累及神经系统者罕见。作者报道1例妇女常年经期剧烈头痛,后证实为反复蛛网膜下腔出血并提示椎管内有子宫内膜组织,并通过抑制雌激素分泌防止出血发作。 Endometriosis involving the nervous system are rare. The authors report a woman with severe headache at perennial menstrual periods, confirmed subsequent subarachnoid hemorrhage and suggestive of endometrial tissue in the spinal canal and prevented the onset of bleeding by inhibiting estrogen secretion.
