MRI abnormalities of the anterior temporal lobe: a new indicator of congenital cytomegalovirus infection.

Abnormalities of the anterior part of the temporal lobe (abnormal and swollen white matter, cysts, and focal enlargement of the anterior part of the inferior horn- either alone or more often in combination) suggest congenital cytomegalovirus (CMV) infection. This is not widely known. These can be seen in neonatal period and they continue to persist in later life.
