Where is the “limbic” encephalitis as mentioned on the title of this case report?

💡Lentiform fork sign on MRI typically points to uremic encephalopathy… but not always. ✅Normal renal function should raise suspicion. In this case, CSF revealed anti-NMDA receptor antibodies → autoimmune encephalitis. doi.org/10.1016/j.radc…

@nirmalregency Fair point. This case is better called autoimmune encephalitis, not limbic encephalitis. No mesial temporal involvement on MRI. “Autoimmune” defines etiology. “Limbic” defines location. Using “autoimmune limbic encephalitis” as a blanket term is misleading.

@OAndrePa Strong association, yes. But MS is likely multifactorial. EBV may be necessary, not sufficient.

@DocNavarrow It is so strongly associated that a vaccine against EBV is being developed for decades to try to stop MS development.

🦠Is Epstein-Barr virus really linked to multiple sclerosis? 🤔Interesting observation supporting a possible long preclinical phase. Makes you wonder how many “silent” biological signals precede MS by years.

A woman was diagnosed with MS in 2019. A cerebrospinal fluid sample (obtained from spinal anaesthesia in a research study) 15 years prior showed antibodies against Epstein-Barr virus (EBV). A case report from Spain pubmed.ncbi.nlm.nih.gov/41841779/
