Summary
Transient ischemic attacks were linked to upright posture in a patient with a cystic mass. This case is the first to document large artery occlusion caused by Cysticercosis racemosus before death.
Area of Science:
- Neurology
- Infectious Diseases
- Vascular Surgery
Background:
- Neurocysticercosis is a significant cause of neurological disease worldwide.
- Large artery occlusion is a rare but serious complication of neurocysticercosis.
Observation:
- A patient experienced transient ischemic attacks (TIAs) triggered by assuming an upright posture.
- Cerebral imaging revealed a cystic mass in the interhemispheric fissure and basilar cisterns.
- Cerebral angiography showed occlusion of the right internal carotid artery.
Findings:
- Surgical exploration identified cysticercosis cysts adhered to the occluded right internal carotid artery.
- This represents the first documented instance of antemortem, direct large artery occlusion due to Cysticercosis racemosus.
Implications:
- This case highlights neurocysticercosis as a potential cause of large artery occlusion and stroke.
- Early diagnosis and treatment of neurocysticercosis are crucial to prevent vascular complications.
- Further research is needed to understand the mechanisms linking cysticercosis to arterial occlusion.
