Insights
Cerebral vasculitis is a rare complication following brain surgery. Early diagnosis and treatment are crucial for improving outcomes in patients experiencing unusual strokes.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Cerebral vasculitis is an uncommon complication post-craniotomy.
- This case report details the diagnosis and management of cerebral vasculitis.
- The etiology of post-craniotomy cerebral vasculitis is discussed.
Observation:
- A 12-year-old boy presented with altered consciousness due to a ruptured arteriovenous malformation (AVM).
- Post-surgery, the patient developed progressive cerebral infarctions, fever, and neurological decline despite hypothermia.
- Angiography revealed arterial narrowing and a "string of beads" phenomenon, indicative of vasculitis.
Findings:
- Steroid therapy led to consciousness recovery, though with severe disability.
- Follow-up angiography one year later showed improvement in vasculitis and AVM occlusion.
- The case highlights the diagnostic challenges and treatment response in post-surgical cerebral vasculitis.
Implications:
- Cerebral vasculitis should be considered in the differential diagnosis of progressive stroke after neurosurgery.
- Timely diagnosis and aggressive treatment are vital for patient recovery.
- This case underscores the importance of recognizing and managing this rare but serious complication.
Background:
Cerebral vasculitis is very rare complication after craniotomy. We report a case and discuss the etiology, diagnosis, and treatment of this complication.
Case Description:
A 12-year-old boy was admitted because of a consciousness disturbance due to a ruptured AVM. Computed tomography revealed a left parietal subcortical hematoma. No apparent nidus was detected on the angiography findings, but AVM was suspected. After resection of the hematoma, the patient did not recover consciousness, and his high fever continued. Despite postoperative induced hypothermia, progressive multiple cerebral infarctions occurred. Postoperative angiography showed multiple arterial narrowing, and a "string of beads" phenomenon was observed in the anterior and posterior circulation in addition to the residual AVM. After administering steroid therapy, he recovered consciousness, but had a severe disability. After angiography, which was performed 1 year after onset, an improvement of the vasculitis and the complete occlusion of AVM were observed.
Conclusion:
We should therefore include cerebral vasculitis in the differential diagnosis when encountering a case with an unusual progressive stroke because a timely diagnosis and aggressive treatment are of critical importance for a successful recovery in such patients.
