Aortic insufficiency caused by Takayasu's arteritis without usual clinical features.

A 30-year-old woman with rapidly progressive, fatal aortic insufficiency was studied. Pathologic studies revealed that the aortic insufficiency was caused by dilation of the aortic root due to Takayasu's arteritis that, unusually, was confined to the ascending aorta and aortic arch. When other diseases that bring about aortic insufficiency can be excluded, Takayasu's arteritis should be considered, even if most of its manifestations are absent.

[Brain abscess (Part 5)--Brain abscess following internal carotid occlusion (author's transl)].

Three cases of brain abscess following an occlusion of the internal carotid artery were reported. Case 1: A 6-year-old girl with congenital heart disease was admitted with headache, disturbance of consciousness and left hemiparesis. Right carotid angiography revealed an occlusion of the right internal carotid artery. After 6 months, she was readmitted with high fever. CT scan revealed a low density area and a ring-like shadow at the same site of cerebral infarction. Case 2: A 69-year-old man was admitted in semicoma and with right hemiplegia. Left angiography revealed an occlusion of the left internal carotid artery. After 2 months, a brain abscess was noted in the infarcted area. Case 3: A 20-year-old man with congenital heart disease, was admitted due to headache, vomiting and high fever. CT scan revealed a brain abscess in the right frontal lobe. Carotid angiography showed bilateral internal carotid artery occlusion. We concluded that diminution of cerebral oxygen and encephalomalacia are predisposing factors to the evolution of brain abscess.
