Tc-99m ECD Brain Perfusion Single-photon Emission Computed Tomography in Parry-Romberg Syndrome.

We report a 15-year-old girl referred to our department for a brain perfusion study with a diagnosis of Parry-Romberg syndrome with left hemifacial atrophy and left enophthalmos. In the presence of a normal magnetic resonance imaging, Tc-99m ECD brain perfusion revealed left temporal lobe hypoperfusion with preserved perfusion in rest of the cortical and subcortical regions and both cerebellar hemispheres.
