A spontaneous cervical epidural hematoma is an infrequent cause of cord compression. The commonest clinical presentations are with paraparesia and tetraparesia. Transient hemiparesia is very rare and a sensory-motor syndrome is exceptional.
A 38 year old man had sudden onset of spontaneous interscapular vertebral pain with bilateral root radiation. A few minutes later he started to have weakness and sensory loss in his right limbs. On clinical examination there was pain on pressure over the spinal apophyses of the T4 and T5 vertebrae, hemiparesia and hemi-hypoalgesia of the right limbs. After ten hours this had all returned to normal. MRI of the cord showed an epidural hematoma extending from C6 to T2. Coagulation studies and spinal arteriography were normal.
The sensory motor syndrome is an unusual form of presentation of a spontaneous cervico-thoracic epidural hematoma. Root pain is a symptom of great value for orientation of a syndrome which would otherwise seem to be of central origin. The explanation for this clinical findings may be compression of both lateral cord pathways due to their particular blood distribution. Regarding therapeutic approach, this should be conservative, with close observation to see whether it will resolve spontaneously in a short period of time.
自发性颈段硬膜外血肿是脊髓受压的罕见原因。最常见的临床表现是双下肢轻瘫和四肢轻瘫。短暂性偏瘫非常罕见,感觉运动综合征则更为罕见。
一名38岁男性突发自发性肩胛间区脊柱疼痛,并伴有双侧神经根放射痛。几分钟后,他开始出现右下肢无力和感觉丧失。临床检查发现,T4和T5椎体棘突压痛,右下肢偏瘫和偏身痛觉减退。10小时后,所有症状均恢复正常。脊髓MRI显示硬膜外血肿从C6延伸至T2。凝血研究和脊髓血管造影均正常。
感觉运动综合征是自发性颈胸段硬膜外血肿的一种不寻常表现形式。根性疼痛是一种非常有价值的症状,有助于明确一种看似源于中枢的综合征。这种临床发现的解释可能是由于双侧脊髓侧索通路的特殊血液分布导致受压。关于治疗方法,应采取保守治疗,密切观察,看其是否会在短时间内自行缓解。
