Parry-Romberg syndrome (PRS), also known as progressive facial hemiatrophy (PFH), is a rare progressive craniofacial disorder (phakomatosis).

It is classically characterized by a slowly progressive degeneration (atrophy) of the soft tissues of half of the face (hemifacial atrophy). This involves the skin, underlying soft tissues, cartilaginous structures and bone.

Epidemiology

There may be slightly increased prevalence in females. It is thought to be of sporadic onset.

Clinical presentation

It typically presents in childhood. The overlying craniofacial skin in the affected region may be hyperpigmented.

Associations

The condition is often accompanied by:

Other possible associations include:

Radiographic features

CT/MRI brain
  • may show atrophy on one side of the face +/- scalp
  • high (T2/PD/FLAIR) signal of white matter within the ipsilateral and less commonly contralateral brain parenchyma has also been reported on MRI
  • ipsilateral and less often contralateral leptomeningeal enhancement
  • ipsilateral parenchymal atrophy
  • ipsilateral cerebral microhemorrhages
  • ipsilateral parenchymal calcification
  • intracranial aneurysms

History and etymology

Caleb Hillier Parry was a British physician (1755-1822), and Moritz Heinrich Romberg was a German neurologist (1795-1873).
