CT scan changes in multiple sclerosis among Malaysian patients

Abstract

A study of 12 patients with clinically definite multiple sclerosis (CDMS) using high dose infusion CT showed overall abnormality of 75% with an average of 2.5 lesions per patient. 75% of the patients showed abnormality of the cerebrum, mostly asymptomatic. The main changes were ventricular dilatation and asymmetry, isolated or generalized cerebral atrophy, areas of low attenuation mainly in the deeper parts of the cerebrum and the peri-ventricular area. 25% of the patients showed changes in the brainstem and none was seen in the cerebellum. The abnormality was more florid in patients with clinically disseminated forms of the disease. The study demonstrated that asymptomatic cerebral involvement is common among Asian patients with MS and CT is a useful tool in the overall assessment and diagnosis of Asian MS patients.
