She had a placental abruption and lost approximately 2000 ml of blood. During the procedure, she received two units of packed red blood cells and intravenous fluids. She has no history of serious illness and takes no medications. She is sexually active with one male partner, and they use condoms inconsistently. She is alert and oriented to person, place, and time. Her temperature is 37.2C 98.9F, pulse is 90min, respirations are 15min, and blood pressure is 9458 mm Hg. Examination shows decreased sensation to temperature and pinprick below her waist and 05 muscle strength in her lower extremities. She feels the vibrations of a tuning fork placed on both of her great toes. Deep tendon reflexes are absent in the lower extremities and 2 in the upper extremities. Which of the following is the most likely diagnosis?? A: Tabes dorsalis, B: Anterior spinal artery syndrome, C: Guillain-Barré Syndrome, D: Brown-Séquard syndrome, E: Posterior spinal artery syndrome,  <response>: This is a clinical vignette describing a 36-year-old woman who has back pain and numbness in her lower extremities after an emergency C-section delivery. She lost a significant amount of blood during the procedure. On exam, she has decreased sensation, weakness, and absent reflexes in her lower extremities but intact vibration sense. Based on the acute onset after blood loss, sensory and motor findings isolated to the lower extremities, and preserved proprioception, this is most consistent with anterior spinal artery syndrome.Tabes dorsalis involves sensory ataxia and absent reflexes but is a chronic condition caused by tertiary syphilis infection. Guillain-Barré would cause weakness but ascending, not isolated to a vascular distribution. Brown-Séquard involves ipsilateral motor and proprioceptive loss with contralateral paintemperature sensory loss, different than this case. Posterior spinal artery syndrome would spare motor function.B: Anterior spinal artery syndrome
