Diffuse enlargement of cerebral vasculature in an adult patient operated for cyanotic congenital heart disease.

A 24-year-old female patient diagnosed with cyanotic CHD had undergone a correction procedure at the age of eight. She had a normal motor and mental development until the age of 23. Later she had functional and cognitive decline following heart failure. Brain MRI showed enlargement of the cerebral arterial and venous system. The changes of central nervous system vasculature occurring in operated cyanotic CHD are not well known. Thanks to advances in this field, more cyanotic CHD patients reach adulthood nowadays and clinicians need to be familiar with the neurological conditions and potential neuroradiological changes.
