Insights
Bilateral intracavernous internal carotid artery aneurysms are rare, particularly in women. Computed tomography angiography revealed these aneurysms in an 81-year-old hypertensive female presenting with cranial nerve palsies.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Bilateral intracavernous internal carotid artery aneurysms are uncommon vascular lesions.
- These aneurysms are more prevalent in elderly females and often linked to hypertension.
- Cranial nerve palsies can be a presenting symptom of these aneurysms.
Purpose of the Study:
- To report the computed tomography angiography findings in a case of bilateral intracavernous internal carotid artery aneurysms.
- To highlight the association between these aneurysms and neurological deficits.
Main Methods:
- A case study of an 81-year-old female patient.
- Clinical examination including assessment of ocular motor function.
- Computed tomography angiography (CTA) for vascular imaging.
Main Results:
- The patient presented with headache, diplopia, and bilateral sixth nerve palsy with left third nerve palsy.
- CTA confirmed the presence of bilateral intracavernous internal carotid artery aneurysms.
- External ocular examination findings were unremarkable.
Conclusions:
- Bilateral intracavernous internal carotid artery aneurysms can manifest with significant neurological symptoms, including multiple cranial nerve palsies.
- CTA is an effective imaging modality for diagnosing these rare aneurysms.
- Prompt neurosurgical consultation is essential for appropriate management of such cases.
Abstract:
Bilateral intracavernous internal carotid artery aneurysms are rare. They are more common in elderly females and are associated with hypertension. We present the computed tomography angiography findings of an 81-year-old female with history of hypertension who came complaining of diplopia and headache. Examination revealed bilateral sixth nerve palsy with left third nerve palsy. External ocular examination was normal. Computed tomography angiography was done and revealed bilateral intracavernous internal carotid artery aneurysms. She was referred to neurosurgery for further management.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
