Syringomyelia?,”Fluid-filled cavity in the spinal cord that may represent dilation of the central canal or a separate cavity within the spinal parenchyma. It most likely presents within the cervical and thoracic spine but can also involve the brainstem. The condition is most likely associated with Arnold Chiari malformation type 1 but may also be acquired from inflammation, infection a tumor, or trauma involving the spine. Typically presents with loss of pain/temp sensation in the dermatomes corresponding to the site of spinal involvement (“”cape distribution””). Vibration/proprioception is preserved as the dorsal spinal column is not usually affected. As the cavity enlarges, there can be interruption of the anterior horn gray matter
resulting in lower motor neuron signs in the upper limbs (areflexic weakness).”
