Abstract
Anterior Spinal Cord Infarction (ASCI) syndrome typically results from ischemia that affects the anterior spinal artery territory characterized by history of sudden onset flaccid paraplegia or quadriplegia depending on the level of the lesion. We describe a 57-years-old woman with sudden onset flaccid weakness of the lower limbs and numbness of the feet of two days duration, preceded by a day history of fever and several episodes of vomiting. Examination initially revealed bilateral hypotonia, hyporeflexia and dense paraplegia, with preservation of dorsal column sensations (fine touch/2-point discrimination, position and vibration sensation). Twenty-four hours thereafter a repeat examination showed hyper-reflexia and extensor plantar response with spastic paraplegia. Thoracic spine Magnetic Resonance Imaging (MRI) revealed thinning of the spinal cord extending from T1 to T9 levels with associated widening of the thecal sac suggestive of anterior spinal cord infarction with no other signal changes seen within the substance.
