Hemiparkinsonism-hemiatrophy (HPHA) is a rare neurological syndrome. The main clinical features of HPHA consist of atrophy of one side of the body (face, trunk, limbs), ipsilateral hemiparkinsonism (bradykinesia, rigidity, tremor) and in many cases dystonia. There are no data on prevalence of HPHA as the condition is rare. The mean age of parkinsonism onset is earlier than in idiopathic Parkinson disease (43.7 years, range: 15–63). Changes in magnetic resonance imaging (MRI) (cortical, basal ganglia atrophy contralaterally to the side of clinical presentation) are described in 30% of patients. The pathogenesis of HPHA is unknown, but in many cases a history of prenatal injuries was reported.

We present two male patients with HPHA – 45 and 55 years old, with left-sided parkinsonism, dystonia and hemiatrophy (to our knowledge, the first Polish cases). Both patients had no atrophic changes in MRI and levodopa treatment was ineffective. In the discussion the authors review current literature on HPHA.
