Cavernous sinus syndrome is a combination of unilateral ophthalmoplegia, autonomic
dysfunction and sensory loss
of the ophthalmic or maxillary branch of the trigeminal nerve. In the case of cavernous
sinus syndrome after a head
injury, we should consider the possibility of a dissecting aneurysm. In addition to
ruptured aneurysms, silent intrac-
ranial aneurysms must also be treated if they cause compression symptoms. In our case
report, we present a 23-year-
old female patient who lost consciousness during a fall, and immediately developed
right-sided ptosis, ophthalmople-
gia and loss of facial sensation. Angiography confirmed a dissection aneurysm of the
right internal carotid artery at
the cavernous sinus, which was treated with a flow diverter on the 6th day after the
injury. The intervention was un-
complicated and resulted in rapid and complete radiological and clinical healing.
Our case report confirms the fact,
based on meta-analyses, that dissection aneurysm occurring at the cavernous sinus
section of the internal carotid
artery can be safely and successfully treated with a flow diverter. If the treatment
is carried out as early as possible, all
the symptoms of the cavernous sinus syndrome can be resolved, and the ipsilateral
ophthalmoplegia and loss of facial
sensation can be completely cured within a few days.
