Diffusion tensor imaging and magnetic resonance spectroscopy in a patient with adult onset tuberous sclerosis complex

We presented a 43-year-old patient with TSC2 mutation, whose symptom was only incomplete quadrantic visual field deficit in spite of multiple brain tubers. The visual field deficit was thought to be due to a small lesion in the upper medial part of the optic radiation revealed by diffusion tensor imaging. Her brain tubers showed normal findings in magnetic resonance spectroscopy. Our case suggested that neurological and neuropsychiatric manifestations of TSC are affected by the quality rather than number of the lesions. In addition, MRS may be useful to identify the correlation between brain tubers and neurological disability in TSC patients.
