A case of unruptured bilateral large carotid-ophthalmic aneurysms, which ap
pear to be adjoining and "kissing" each other when visualized by three-dime
nsional computed tomographic angiography (3-D CTA), is reported. Although b
ilateral carotid-ophthalmic aneurysms are not rare, bilateral large ones ar
e quite rare, and direct imaging of "kissing aneurysms" of this portion has
not been reported. Since 3-D CTA is becoming a useful tool for the diagnos
is of cerebral aneurysms, we propose that these and similar bilateral large
carotid-ophthalmic aneurysms are good candidates for the term "kissing ane
urysms".
