A 56-year-old man with prior left hand Dupuytren’s contracture suddenly developed
a right hand Dupuytren’s contracture-like posturing ([Figure A]). Bilateral palmar fascial thickening with flexion deformity of the fingers was
noted. Neurological examination also disclosed weakness of the right wrist and finger
extension, as well as of thumb and index finger abduction. Brain MRI revealed an acute
infarction in the left precentral “hand knob” area[1],[2],[3],[4] ([Figure B], [C] and [D]). We emphasize that Dupuytren’s contracture, a supposedly straightforward orthopedic
disorder, can be a stroke chameleon. By unbalancing a previous subclinical condition,
due to predominant weakness in the extensors, cortical “hand knob” infarction presented
as an “acute Dupuytren’s contracture” in this patient.
