Completely thrombosed giant fusiform aneurysm in a young patient--case report

Thrombosed giant aneurysm of the pericallosal artery with inconclusive findings of multiple neuroimaging studies

A 65-year-old woman presented with a thrombosed giant pericallosal artery aneurysm manifesting as headache and memory loss that developed over a 2-year period. Computed tomography (CT), magnetic resonance (MR) imaging, and conventional and CT angiography could not establish the differential diagnosis. Open craniotomy revealed the mass as thrombosed giant aneurysm from the pericallosal artery. Direct clipping with thrombectomy was performed successfully with an uneventful postoperative course. Thrombosed giant aneurysm of the distal anterior cerebral artery should be considered in the differential diagnosis of an unusual mass in the mid-frontal area, particularly in the presence of inconclusive angiographic and MR imaging findings.

Recanalization of completely thrombosed giant aneurysm: case report

BACKGROUND

Spontaneous recanalization in a completely thrombosed giant aneurysm is a very rare condition.

CASE DESCRIPTION

An 18-year-old woman presented with a serpentine variety giant aneurysm of the posterior cerebral artery, in which spontaneous recanalization of a completely thrombosed lumen was demonstrated on magnetic resonance imaging and angiography. The patient was treated by trapping of the parent artery and aneurysmectomy.

CONCLUSION

This case will provide insight into the potential for spontaneous recanalization in completely thrombosed giant aneurysms.
