[A case of thoracic spondylosis presented with an attack of abnormal sensation and hyperhydrosis on the upper back]

A 23-year-old man presented an attack of abnormal sensation and hyperhydrosis on his upper back when he was tense or took a bath. This presentation continued for a month after commencement of Judo practise. Neurological examination found hyperactivity of bilateral deep tendon reflex alone. Magnetic resonance image demonstrated that the anterior thoracic spinal cord at the Th 4/5, 5/6 and 7/8 level were compressed by a bony spur. In our case, limitation of exercise, and prescription of adenosine triphosphate disodium and vitamin B led to a favourable outcome. Thoracic spondylosis in a young person is rare and there have been no standard protocols for the treatment. Thus, further clinical investigations are warranted.
