A case of Bilateral anterior thalamic symmetrical infarction

Abstract

Background: Bilateral anterior thalamic symmetrical infarction is very rare in clinical practice and has not been reported so far. Here, we introduce a patient with symmetrical bilateral anterior thalamic infarction, and discuss his symptoms, treatment process, late follow-up and potential mechanisms. Case presentation: A 71-year-old male had a sudden cognitive decline 4 days ago. The patient's brain MRI showed symmetrical high signals in the anterior part of bilateral thalamus. The patient's head MRV and immunological tests were normal. We consider this patient as a rare bilateral anterior thalamic infarction. After 10 days of anti-platelet aggregation, lowering blood lipid and improving circulation, the patient's symptoms improved significantly. Two years later, we found through telephone follow-up that the patient's symptoms did not change significantly, he was completely self-care, his reaction was normal, and only a slight recent memory decline was left. Conclusion: For patients with bilateral anterior thalamic lesions with only acute cognitive impairment, the diagnosis of acute cerebral infarction should be taken into account, and the treatment plan for cerebral infarction should be given as soon as possible.
