Multiple sclerosis with bilateral continuous cystic lesions along lateral ventricles and caudate-callosal angles (Wetterwinkel).
We report a 53-year-old female autopsy case of multiple sclerosis with bilateral continuous cystic lesions along the lateral ventricles and caudate-callosal angles (Wetterwinkel). The pathophysiological mechanisms underlying these peculiar huge cystic lesions can be explained by the appearance of necrotic tissue during the recurrent relapsing stages of the disease, and then, by the absorption and scavenging of activated microglias. Poor astrocytic gliosis, which might be an effect of frequent use of corticosteroids during the clinical course makes the cavities bigger.
