A misleading distal anterior cerebral artery aneurysm
BACKGROUND Aneurysmal rupture causing pure acute subdural hematoma (aSDH) is rare. In the four previously reported cases of distal anterior cerebral artery (ACA) aneurysm resulting in pure aSDH, blood distribution in the interhemispheric (IH) space has systematically incriminated the distal ACA as the source of rupture. We present a misleading case of a distal ACA rupture resulting in convexity...
متن کاملPosterior communicating artery aneurysm associated with duplicated posterior communicating artery and bilateral fetal posterior cerebral arteries.
Because of the location, skull-base chordomas often present with headaches and diplopia and sixth and fifth nerve palsies are the most common neurological signs.[1,2] The interval between onset of symptoms and diagnosis of clival chordoma is quite variable, 2.5-4.4 years.[4] The uncommon clinical presentations include: Nasal obstruction, nasal bleeding, and subarachnoid hemorrhage.[3,5] Spontan...
متن کاملDistal anterior cerebral artery aneurysms.
BACKGROUND Distal anterior cerebral artery (DACA) aneurysms, also known as pericallosal artery aneurysms, represent about 6% of all intracranial aneurysms. They are located on the A2-A5 segments of the anterior cerebral artery and on its distal branches. METHODS This paper summarizes present knowledge on radiological features, treatment options, treatment results, and long-term follow-up of D...
متن کاملAzygos anterior cerebral artery aneurysm associated with fenestration of the anterior cerebral artery.
Azygos ACA (Alpers et al. 1959; Bap tista et al. 1963; Pool et al. 1965), triple ACA (Baptista et al. 1963) and A1 fenestration (A1 pers et al. 1959; Crompton, 1962; Baptista et al. 1963; Teal et al. 1973; Ito et al. 1981; Krayenbuhl et al . 1982) are known as anomalies related to the anterior cerebral artery (ACA). Each of them is a rare vascular anomaly, and only a few reports have been prese...
متن کاملAzygos anterior cerebral artery mimicking an anterior communicating artery aneurysm.
The CT appearance of intracranial aneurysms has been well described. Though a definitive diagnosis often requires angiography, the CT findings are often highly suggestive of these frequent , potentially lethal, and curable vascular lesions. We recently encountered a patient who had the typical CT findings of intracranial aneurysm but whose arteriographic findings showed a large azygos anterior ...
