Dyke–Davidoff–Masson syndrome: description of clinical case with diagnostics by EEG, MRI, MR-tractography, fMRI

Abstract

Dyke–Davidoff–Masson syndrome is a possible cause of several pathologies and has rare appearance in clinical practice. One of these causes is a perinatal stroke. The man 59‑year‑old applied to the Federal center of brain and neurotechnologies had this one. The patient had bilateral tonic‑clonic seizures with loss of consciousness, and remission was observed during the last 4 years with antiepileptic drugs treatment. Complex radiological and func‑ tional diagnostics were performed with electroencephalography, magnetic resonance imaging, magnetic resonance tractography, functional magnetic resonance imaging. As a result of research many signs of Dyke–Davidoff–Masson syndrome were found. On the example of damage in the perinatal period and subsequent adaptation of the brain, its plasticity with respect to speech function was shown.
