[Complex Regional Pain Syndrome--an unusual etiology]

Complex Regional Pain Syndrome type 1 is characterised by neuropathic pain associated with autonomic dysfunctions. It frequently appears after major or minor trauma and more rarely may originate from conditions that compromise the central nervous system. Although few treatments have shown to be effective, their institution at an early stage is decisive for their success. For this reason it is important to ensure timely recognition of this clinical entity, attempting to identify its cause and the predominant underlying physiopathological mechanisms whenever possible. The authors describe a case of complex regional pain syndrome type 1, emphasising the rarity of this clinical situation in association with a Parkinsonian Syndrome.
