Reversible Pisa syndrome associated to subdural haematoma: case-report

Background Pisa Syndrome or Pleurothotonus is a relatively rare truncal dystonia, characterized by tonic flexion of the trunk and head to one side with slight rotation of the body. Since frequently associated to specific drugs such as antipsychotics and cholinesterase inhibitors or to Parkinson Disease, a pathophysiological role of cholinergic-dopaminergic imbalance has been suggested. We report here the first case of Pisa Syndrome due to an extracerebral pathology as subdural haematoma.
