  • 척수 경색은 고양이에서 급성 척수 병증의 주요한 원인으로써 인식되고 있다. 사후 조직 병리학적 검사를 통해 확진 할 수 있지만 MR 영상학적 특징은 척수 경색의 진단에 가치있는 정보를 제공한다. 본 증례의 목적은 두 마리의 고양이에서 발생한 급성 척수 경색의 영상학적 특징을 설명하고 그 진단에 있어서 low field MRI (0.3 Tesla)의 유용성을 평가하는 것이다. 미확인 연령의 중성화 수컷, mixed breed 고양이가 급성의 사지 부전 마비를 주증으로 내원하였고 9살령의 중성화 암컷 domestic short hair 고양이는 후지 부전 마비로 내원하였으며 하루 후 후지 완전 마비가 나타났다. 이후 실시된 MR 영상에서 첫번째 고양이의 경우 두번째 경추부터 여섯번 째 경추 수준의 척수에서 병변이 분포하였으며 두번째 고양이의 경우 두번째 요추부터 다섯번째 요추 수준에서 병변이 나타났다. 두 고양이에서 공통적으로 주로 회백질에 분포한 척수 실질 내에 국소적인 병변이 확인되었으며 T2 강조 영상 및 FLAIR 영상에서 고신호를 나타내었고 DWI 영상에서 고신호, ADC map 에서는 저신호를 나타내었다. 히스토리, 임상증상 및 다른 실험실적 검사와 함께 MR 영상학적 특징을 통해 두 고양이에서 급성 척수 경색이 진단되었다.

  • Spinal cord infarction is uncommon and usually presents with sudden onset of motor and sensory disturbances. We report a case of a 64-year-old women without previous medical history, who presented with acute onset of paraplegia after lifting. However, radiologic examinations did not show any abnormal lesion in the spinal cord. And, cerebrospinal fluid studies also showed no remarkable findings. This case illustrates the cause of spontaneous paraplegia after lifting injury and we consider the presumptive cause of paraplegia as spinal cord infarction.

  • Authors report a case of a painless acute dissecting aneurysm of the descending aorta in a patient who presented with unexplained hypotension followed by simultaneous paraplegia and right arm monoparesis. To our knowledge, case like this has not been reported previously. Magnetic resonance imaging of the brain and spine revealed hemodynamic cerebral infarction and extensive cord ischemia, respectively. Computerized tomography angiography confirmed a dissecting aneurysm of the descending aorta. The cause of the brain infarction may not have been embolic, but hemodynamic one. Dissection-induced hypotension may have elicited cerebral perfusion insufficiency. The cause of cord ischemia may be embolic or hemodynamic. The dissected aorta was successfully replaced into an artificial patch graft. The arm monoparesis was improved, but the paraplegia was not improved. In rare cases of brain and/or spinal cord infarction caused by painless acute dissecting aneurysm of the aorta, accurate diagnosis is critical because careless thrombolytic therapy can result in life-threatening bleeding.

  • Nontraumatic intracranial subarachnoid hemorrhage (SAH) attributable to the thoracolumbar dural arteriovenous fistulas (DAVFs) has been extremely rare. A 41-year-old male patient was admitted with severe acute headache, neck stiffness, and pronounced low-back pain radiating to both legs. The T2-weighted MR imaging showed irregular signal void and enlarged, varix like pouch formation with spinal cord compression at the T11-12 level. The angiogram revealed a DAVF. We report a DAVF case with SAH that revealed an extensive infarction from C5 to the conus medullaris after undergoing operative treatment.

  • Cervical epidural steroid injection is frequently used in the conservative management of neck pain and cervical radiculopathy. Epidural cervical transforaminal injections are usually well-tolerated with mild side effects such as transient decreased sensory and motor function, or headache due to dural puncture. Although there are a few case reports about adverse effects of cervical epidural injection in the literature, it can cause severe complications such as large hematoma, infarction by spinal vascular injury. Subdural hematoma has been occurred much less common rather than epidural hematoma in the spinal cord. We report a rare catastrophic case of cervical spinal subdural hematoma with quadriparesis after cervical transforaminal epidural block.

  • Fat embolism syndrome is a rare but alarming, life-threatening clinical condition attributed to fat emboli entering the circulation. It usually occurs as a complication of long-bone fractures and joint reconstruction surgery. Neurological manifestations usually occur 12 to 72 hours after the initial insult. These neurological complications include cerebral infarction, spinal cord ischemia, hemorrhagic stroke, seizures, and coma. Other features include an acute confusional state, autonomic dysfunction, and retinal ischemia. In this case series, we describe three patients with fat embolism syndrome who presented with atypical symptoms and signs and with unusual neuroimaging findings. Cerebral fat embolism may occur without any respiratory or dermatological signs. In these cases, diagnosis was established after excluding other differential diagnoses. Neuroimaging using brain magnetic resonance imaging is of paramount importance in establishing a diagnosis. Aggressive hemodynamic and respiratory support from the beginning and consideration of orthopedic surgical intervention within the first 24 hours after trauma are critical to decreased morbidity and mortality.
