Summary
This case report details a rare ruptured inflammatory aneurysm linked to neurocysticercosis in the anterior temporal artery. Histological confirmation highlights this unique association, offering new insights into vascular inflammation.
Area of Science:
- Neurology
- Vascular Surgery
- Infectious Diseases
Background:
- Subarachnoid hemorrhage can result from ruptured aneurysms.
- Neurocysticercosis is a parasitic infection affecting the brain.
- Inflammatory aneurysms are uncommon vascular pathologies.
Observation:
- A 69-year-old man presented with subarachnoid hemorrhage and intracerebral hematoma.
- Computerized tomographic angiography suggested a middle cerebral artery aneurysm.
- Surgery revealed a cystic mass (neurocysticercosis) and an aneurysm on an anterior temporal artery branch.
Findings:
- The aneurysm was inflammatory and located beneath a neurocysticercosis cyst.
- Histopathological examination confirmed the inflammatory nature of the aneurysm and neurocysticercosis.
- The aneurysm was successfully treated by trapping.
Implications:
- This case represents the first reported instance of a ruptured inflammatory aneurysm associated with neurocysticercosis.
- Understanding this association may improve diagnosis and treatment of complex cerebrovascular conditions.
- Further research into the pathogenesis of inflammatory aneurysms in infectious contexts is warranted.
