| Abstract: | Summary Clinically apparent brain dysfunction is common in myotonic dystrophy. In a sample of fourteen adult patients with the definite form of this disease, brain magnetic resonance imaging detected frequent white matter abnormalities and ventriculomegaly. In addition, two patients exhibited an intracranial arachnoid cyst, a condition of neurosurgical interest that could be related to the generalized dysmaturational process present in this disease. Patients with myotonic dystrophy deserve a careful screening for brain involvement. Further MRI studies should ascertain the actual prevalence of brain anomalies in myotonic dystrophy and define the role of this procedure in the workup of this disease. |
