AI Article Synopsis

  • * The first documented case of RESLES occurred after elective surgery for a distant arteriovenous malformation (AVM), which resulted in mild speech difficulties and an observable MRI lesion in the corpus callosum.
  • * The lesion exhibited cytotoxic edema but completely resolved within 15 days, suggesting that post-surgery adjustments to new blood flow patterns could lead to the development of RESLES.

Article Abstract

Isolated lesions of the corpus callosum are rare and may represent permanent but also transient responses to various pathology termed "reversible splenial lesion syndrome" (RESLES) when in light of relevant clinical presentation. We present the first case of the RESLES after elective surgery for distant arteriovenous malformation (AVM), followed by a slight speech disturbance and MRI verified small, oval, well-circumscribed area of apparent cytotoxic edema in the center of the corpus callosum splenium, which completely resolved within 15 days. Surgery for AVM is followed by the complex adaptation to a new vascular pattern, RESLES might develop, and should be suspected.

Background: The reversible splenial lesion syndrome is frequently associated with systemic and central nervous system infections. Whether an infection associated with the occurrence of the reversible splenial lesion syndrome could play a role in the later development of multiple sclerosis is unknown.

We describe the case of an 88-year-old man with cytotoxic lesions of the corpus callosum (CLOCCs) related to hypoglycemia. The patient developed a disturbance of consciousness following excessive alcohol consumption and anorexia. In the emergency room, his blood sugar level was 9 mg/dL, and he was immediately treated with a rapid infusion of glucose.
