We present a right-hemispheric stroke patient with complex regional pain syndrome (CRPS). The regional cerebral blow flow (rCBF) as determined using single photon emission computed tomography (SPECT) showed contralateral increase of tracer uptake in the left thalamus accompained by crossed cerebellar diaschisi (CCD) in the left cerebellum. After rehabilitation, the CRPS in the right upper extremity recovered, although hemiplegia persisted on the left limbs. The rCBF determined a second time using SPECT showed that uptake was normal in the bilateral thalami, basal ganglia and bilateral cerebella. At a 6-month follow-up, the CRPS had not recurred. Our findings show that analysis of rCBF by SPECT is useful for the clinical evaluation and follow-up of CRPS. To the best of our knowledge, this is the first reported case with this particular pattern of symptoms and symptom resolution. (c) 2007 Elsevier Ltd. All rights reserved.
