Background and Purpose-We report the first case of pituitary apoplexy cause
d by the rupture of an intracavernous carotid artery aneurysm embedded in a
pituitary adenoma.
Case Description-A 46-year-old man presented with clinical and CT findings
typical of pituitary apoplexy. MRI showed an unusual flow-void protrusion i
nto the intratumoral hematoma, which, however, was not diagnosed as a ruptu
red aneurysm until severe intraoperative bleeding occurred. Angiography aft
er surgery revealed an intracavernous carotid artery aneurysm.
Conclusions-The possible association of adenoma and aneurysmal rupture shou
ld be kept in mind when assessing any case of pituitary apoplexy.
