perivenous การใช้

• Therefore, some authors propose to establish the separation line in the shape of the lesions around the veins, being therefore " perivenous vs . confluent demyelination"
• Inflammation in ADEM is widely disseminated and ill-defined, and finally, lesions are strictly perivenous, while in MS they are disposed around veins, but not so sharply.
• The scleroses that define the disease are the remainders of previous demyelinating lesions in the CNS white matter of a patient ( encephalomyelitis ) showing special characteristics, like for example confluent instead of perivenous demyelination.
• Nevertheless, the co-occurrence of perivenous and confluent demyelination in some individuals suggests pathogenic overlap between acute disseminated encephalomyelitis and multiple sclerosis and misclassification even with biopsy or even postmortem ADEM in adults can progress to MS
• A special characteristic that makes a difference between MS and the several kinds of ADEM is the structure of the lesions, being strictly perivenous in ADEM and showing a confluence around veins in MS . Given that ADEM can be multiphase sometimes and MS can appear in children, this characteristic is often considered as the line that separates both conditions.
