Venous sinus diverticula causing pulsatile tinnitus can be successfully treated with stent-assisted coil embolization with complete resolution of clinical symptoms. This is in concordance with 13 case reports in the literature involving 14 patients with venous sinus diverticula treated using endovascular techniques.

Aneurysms of the cavernous segment of the internal carotid artery (ICA) are believed to have a low risk of subarachnoid haemorrhage (SAH), given the confines of the dural rings and the anterior clinoid process. The risk may be greater when the bony and dural protection has been eroded. We report a case of spontaneous SAH from rupture of a cavernous ICA aneurysm in a patient whose large prolactinoma had markedly decreased in size as the result of cabergoline treatment. After passing a balloon test occlusion, the patient underwent successful endovascular vessel deconstruction. This case suggests that an eroding skull base lesion may distort normal anterior cranial base anatomy and allow communication between the cavernous ICA and subarachnoid space. The potential for SAH due to cavernous ICA aneurysm rupture should be recognised in patients with previous pituitary or other skull base lesions adjacent to the cavernous sinus.

effective strategy against pulmonary coagulopathy. We fully agree with Dr. Traber that currently there is not enough information from clinical trials that nebulization of heparin is really beneficial. 3 We are currently starting up a multicenter double-blind placebocontrolled randomized clinical trial of burn patients with inhalation trauma in The Netherlands and Belgium evaluating the effects of early nebulized heparin.
