Rationale: Intraspinal anesthesia, the most common anesthesia type of orthopedic operation, is regarded as safe and simple. Despite of the rare incidence, puncture related complication of intraspinal anesthesia is catastrophic for spinal cord. Here we present an intradural hematoma case triggered by improper anesthesia puncture. The principal reason of this tragedy was rooted in the neglect of spine deformities diagnosis before anesthesia. To the best of our knowledge, there is no specific case report focusing on the intradural hematoma triggered by improper anesthesia puncture., Patient Concerns: Hereby a case of thoracolumbar spinal massive hematoma triggered by intraspinal anesthesia puncture was reported. The presenting complaint of the patient was little neurologic function improvement after surgery at 6-month follow-up., Diagnoses: Emergency MRI demonstrated that massive spindle-like intradural T2-weighted image hypointense signal masses from T12 to S2 badly compressed the dural sac ventrally, and his conus medullaris was at L3/4 intervertebral level with absence of L5 vertebral lamina. Hereby, the diagnoses were congenital spinal bifida, tethered cord syndrome, spine intradural hematoma, and paraplegia., Interventions: Urgent surgical interventions including laminectomy, spinal canal exploration hematoma removal, and pedicle fixation were performed. The patient received both medication (mannitol, mecobalamin, and steroids) and rehabilitation (neuromuscular electric stimulation, hyperbaric oxygen)., Outcomes: Postoperation, he had regained only hip and knee flexion at II grade strength. His neurologic function was unchanged until 3 weeks postoperation. Six-month follow-up showed just little neurologic function improvement, and the American Spinal Injury Association grade was C., Lessons: By presenting an intradural hematoma case triggered by improper anesthesia puncture, we shared the treatment experience and discussed the potential mechanism of neurologic compromise. The principal reason for this tragedy is preanesthesia examination deficiency. Necessary radiology examinations must be performed to prevent misdiagnosis for spinal malformation.

Rationale: Tertiary syphilis can manifest as gummatous disease, but gumma of the spine has been extremely rarely reported., Patient Concerns: A 61-year-old male complained of worsening pain and numbness in both lower legs for four weeks., Diagnoses: Syphilis of the Lumbar Spine., Interventions: Pedicle screw fixation (L3-S1) and posterior decompression of the vertebral canal at L4-5 were performed., Outcomes: The postoperative VAS score of both lower extremities decline to 2 from 7 at admission. Dorsal thumb extensor motor power (left/right) at day 7 postoperatively was 3/3 (versus admission: 1/1). Laboratory examinations showed normal white blood cell count (versus admission: 13.8 × 10/L; reference value: 4.00-10.00 × 10/L) and decline in C-reactive protein (20.35 mg/L versus admission: 77.43 mg/L; reference value: 0.00-10.00 mg/mL) and ESR (58 mm versus admission: 73 mm; reference value: 0-15 mm)., Lessons: Our case illustrates that although gummatous disease of the spine may be extremely rare, it should be considered in the differential diagnosis of tuberculosis or malignancy of the spine so as to avoid a wrong diagnosis and incorrect treatment., (Copyright © 2017 The Authors.
