Polyarteritis nodosa presenting with bilateral cavernous internal carotid artery aneurysms.

A 24-year-old man was admitted with a severe, abrupt-onset headache and diplopia.

Cerebral angiography demonstrated bilateral aneurysms on the cavernous portion of the internal ICA, measuring 2.4 cm on the left and 2 cm on the right (figure, A and B). Abdominal ang...

Bilateral Carotid-Cavernous Fistulas: An Uncommon Cause of Pituitary Enlargement and Hypopituitarism

Carotid-cavernous fistulas (CCFs) are rare, pathologic communications of the carotid artery and the venous plexus of the cavernous sinus. They can develop spontaneously in certain at risk individuals or following traumatic head injury. Typical clinical manifestations include headache, proptosis, orbital pain, and diplopia. We report a case of bilateral carotid-cavernous fistulas associated with...
