DYKE-DAVIDOFF-MASSON SYNDROME - TYPICAL IMAGING FEATURES.

INTRODUCTION

Dyke-Davidoff-Masson syndrome is an uncommon neurological disorder clinically presented with seizures, various degrees of mental retardation, motor weakness and sometimes body asymmetry. Typical neuroimaging features include cerebral hemiatrophy with ipsilateral hyper pneumatization of paranasal sinuses. The purpose of this report was to present a rare cause of seizures revealed by Magnetic resonance imaging.

CASE REPORT: We report a case of a 17-year-old boy admitted to hospital due to a severe headache. He had been treated because of partial epileptic seizures for six years. Neuropsychological examination revealed mild mental retardation, mild speech and reading difficulties and discrete right-sided hemiparesis. Typical magnetic resonance imaging features confirmed clinical suspicion of Dyke-Davidoff-Masson syndrome. revealing left frontal lobe atrophy, with consecutive widening of the left lateral ventricle frontal horn, thickening of the nearby frontal squama and hypertrophy of left frontal sinus.

CONCLUSION

Magnetic resonance imaging is the key imaging modality that confirms clinical suspicion of Dyke-Davidoff-Masson syndrome based on a proper physical and neurological examination.
