The following are Components of Brown sequard syndrome except: (A) Ipsilateral extensor plantar response, (B) Ipsilateral pyramidal tract involvement, (C) Contralateral spmothalamic tract involvement, (D) Contralateral posterior column involvement
Answer is D. . *The sensations that are transmitted only in dorsal and dorsolateral columns-kinesthetic and position sensations,vibration sensation, discrete localization and 2 point discrimination are lost on the side of transection because fibers in this column do not cross to opposite side until they reach medulla Brown-Sequard syndrome is characterized by loss of motor function (i.e. hemiparaplegia), loss of vibration sense and fine touch, loss of proprioception (position sense), loss of two-point discrimination, and signs of weakness on the ipsilateral (same side) of the spinal injury. ref Harrison20th edition pg 2700
