Introduction: Dyke–Davidoff–Masson Syndrome (DDMS) is a clinical syndrome that causes different clinical symptoms and is defined by volume decrement in one cerebral hemisphere. In this study, we aimed to evaluate the involvement of the normal-appearing contralateral hemisphere in 16 pediatric patients with DDMS using diffusion-weighted imaging (DWI). Materials and methods: Brain MRIs were retrospectively reviewed between January 2014 and January 2023. Sixteen pediatric patients radiologically compatible with DDMS were included in the study. Sixteen children who had undergone brain MRI, most commonly for headaches and whose MRI findings had been completely normal, were included as the control group. Apparent diffusion coefficient (ADC) values of the deep gray and white matter of the normal-appearing hemisphere in the patient group were calculated and compared with that of the control group. Results: The ADC values of the gray and white matters of the patient and control groups were not statistically different. However, in the patient group, the ADC values of the gray and white matters in males were remarkably lower than in females (p = 0.038, p = 0.037, respectively). Conclusion: The difference in the ADC values of the contralateral hemisphere between females and males in the patient group suggests that the normal-appearing hemisphere may have been affected by DDMS. Although, the exact mechanism of this effect is not known. Therefore, in patients with DDMS, contralateral hemisphere involvement in cerebral hemiatrophy and hemispherectomy should be evaluated clinically and radiologically.
