Role of developmental venous anomalies in etiopathogenesis of demyelinating diseases

Objective: Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. T2W-hyperintense demyelinating lesions are detected in cranial magnetic resonance imaging (MRI). Developmental venous anomalies (DVAs) have frequently been detected in enhanced cranial MRI images,...

Description
Summary:Objective: Multiple sclerosis (MS) is a demyelinating autoimmune disease of the central nervous system. T2W-hyperintense demyelinating lesions are detected in cranial magnetic resonance imaging (MRI). Developmental venous anomalies (DVAs) have frequently been detected in enhanced cranial MRI images, and are generally accepted as normal variants of venous development. The aim of the present study was to investigate whether there was an association between demyelinating diseases and venous anomalies. Methods: One hundred five patients who were diagnosed as having MS in accordance with the McDonald diagnostic criteria, and 105 patients who were diagnosed as having vascular headache who had no lesions similar to MS were included in the present retrospective study. Results: DVAs were detected in 31 of the study group and in 14 patients in the control group. A statistically significant higher rate of DVAs and abnormal signal increase in the neighboring tissue was detected in the study group (p = 0.004) (p = 0.006). The DVA was superficially localized in the RRMS, It was deeply located in RIS. Conclusion: Recent studies have emphasized the association of the central vein and the lesion severity of MS with the detection of the central collecting vein in MS lesions. In our study, DVAs, which are generally regarded as innocent developmental anomalies, and neighboring signal increase were found significantly higher in the MS group compared with the control group. The role of DVAs in the etiology of demyelinating lesions must be clarified through comprehensive future studies that use more advanced techniques.
