Neuraxial anaesthesia is widely used in surgical procedures; overall, epidural\nand intrathecal techniques. Nevertheless, several outcomes should be considered.\nThe incidence of neurologic complications after neuraxial anaesthesia\nis not perfectly clear (0% - 0.08%), although there are several described cases\nof spinal cord ischemia. We present a case of thoracic unilateral spinal cord\nsyndrome following lumbar spinal anaesthesia for periprosthetic knee fracture.\nOur patient suffered monoparesis in her left lower limb as well as decreasing\nof muscle strength and loss of tendon reflexes. The MNR showed left\nhyperintense intra-cord images from T7 to T12 attributed to spinal cord\noedema and a lineal hypointensity related to minimal haematic component.\nWhat made this case surprising was the fact that spinal anaesthesia was performed\nbetween L3 and L4 and the patient did not suffer paraesthesia associated\nwith local anaesthetic injection. She was treated with glucocorticoids,\ngabapentin and amitriptyline. She also was checked by physical rehabilitators,\nneurologists and Pain Unit physicians. We have found another case reported\nin the literature about thoracic cord injury after lumbar spinal puncture. In\nthis paper, we report possible aetiologies according to a review and neurological\nevolution of the patient seven months later.
