“…10,20,25) The diagnosis of intracranial dissecting aneurysms is not easy, even with angiography. 8,9,15,16,18,19,23) Angiographic characteristics of dissecting aneurysms include the pearl and string sign, narrowing, fusiform dilatation, and occlusion, but these are not specific. The pathognomonic sign for dissecting aneurysm may be double lumen, but this is infrequently found.…”

“…13) Intracranial dissecting aneurysms can be classified into two types according to the different planes of the dissecting lamina of the arterial wall, in which type 1 (submedial dissection) is likely to cause cerebral infarction and type 2 (subadventitial dissection) to cause SAH. 25) The etiology of dissecting aneurysms remains obscure in most cases, 3,4,6,9,15,16) but the dissection is known to be related to such diseases as migraine, fibromuscular dysplasia, mixed connective tissue disease, and trauma. 10,20,25) The diagnosis of intracranial dissecting aneurysms is not easy, even with angiography.…”

A 46-year-old woman presented with a dissecting aneurysm of the right middle cerebral artery manifesting as subarachnoid hemorrhage followed by hemorrhagic infarctions. The aneurysm was clipped and wrapped. However, serial angiography showed progression of the lesion, which was probably responsible for the clinical course of this patient. Intracranial dissecting aneurysms are less common, and the natural history of these lesions is unclear. Conservative management might be preferable in this patient.

“…Anterior dissecting aneurysms are rare, occur more likely in internal carotid and middle cerebral arteries (5) and are commonly revealed by ischemic attack. ACA dissecting aneurysms are known to occur in younger patients (13) (mean age 48.2 years) with a slight male predominance (12).…”

We report the case of a large dissecting aneurysm of the anterior cerebral artery revealed by cerebral infarction in 38-year-old man. The volume and aspect of the aneurysm initially led us to the diagnosis of saccular aneurysm. Given the complete thrombosis, the risk of bleeding was low and antithrombotic therapy was started. Surgery could be discussed later. However radiological monitoring by MRI (magnetic resonance imaging) showed a rapid decrease in volume of the aneurysm. The final angiography found an aspect of stenosis followed by a little arterial dilatation. The diagnosis of dissecting anterior cerebral aneurysm was a posteriori established.KEywOrds: Dissecting aneurysm, Ischemic stroke, Haemorrhage, Angiography ÖZ 38 yaşında bir erkekte serebral infarktüsle ortaya çıkan anterior serebral arterin büyük disekan anevrizması olgusunu bildiriyoruz. Anevrizmanın büyüklüğü ve yeri başlangıçta sakküler anevrizma tanısı düşündürdü. Tam tromboz olduğu dikkate alındığında kanama riski düşüktü ve antitrombotik tedavi başlandı. Cerrahi seçeneği daha sonra değerlendirilecekti. Ancak manyetik rezonans görüntüleme (MRG) ile radyolojik izleme anevrizmanın hacminde hızlı bir azalma gösterdi. Son anjiyografi bir miktar stenoz ve sonrasında biraz arteriyel dilatasyon buldu. Sonradan disekan anterior serebral anevrizma tanısı kondu.
