“…Other causes of intracranial pseudoaneurysms include Marfan's syndrome, fibromuscular dysplasia, vasculitis, rupture of true cerebral aneurysm or arteriovenous malformation, associated with moyamoya disease, and radiotherapy (4,5,33,34). Dissecting pseudoaneurysms and blood blister-like aneurysms were out of the scope of the discussion.…”

“…Angiography should be used for patients with perioperative hemorrhage or epistaxis. Digital subtraction angiography (DSA) is still the gold standard for the diagnosis of intracranial pseudoaneurysms since CTA and MRA have limited sensitivity for the detection of small aneurysms ( 44 ) DSA often demonstrates a globular shaped aneurysmal sac without a neck ( 5 ). Delayed filling and stagnation of contrast agents are the features of the pseudoaneurysm.…”

“…The most common cause of pseudoaneurysm is trauma (2). Other causes are iatrogenic, infectious disease, radiation exposure, connective tissue disease, and sometimes they occur spontaneously (3)(4)(5)(6). A pseudoaneurysm or false aneurysm is the product of damaging vessel wall resulting in an encapsulated hematoma in communication with the ruptured artery.…”

Intracranial pseudoaneurysms account for about 1% of intracranial aneurysms with a high mortality. The natural history of intracranial pseudoaneurysm is not well-understood, and its management remains controversial. This review provides an overview of the etiology, pathophysiology, clinical presentation, imaging, and management of intracranial pseudoaneurysms. Especially, this article emphasizes the factors that should be considered for the most appropriate management strategy based on the risks and benefits of each treatment option.

“…Thus, strong and homogenous enhancement of hyperdense nodule in a hematoma may be an indicator of pseudoaneurysm. It has also been suggested that enlarging parenchymal hematoma and atypical hematoma evolution on CT scan should lead to angiographic validation (20). Several other studies suggested that CT angiography is a useful and effective tool to confirm the diagnosis of pseudoaneurysm (4,19).…”

Traumatic pseudoaneurysm of the middle meningeal artery (MMA) is a rare entity that is typically associated with a high risk of rupture and mortality. Only few such cases of pseudoaneurysms have been reported in the medical literature and therefore, the optimal management of this condition remains undetermined. The present study reported on a female patient (age, 20 years) with angiographically progressive pseudoaneurysm of the MMA after head injury. The pseudoaneurysm was successfully embolized with the liquid, non-adhesive embolic agent Onyx™. The mechanism of formation of traumatic pseudoaneurysms, their imaging characteristics and the optimal treatment plan were discussed.

“…Various pathological or idiopathic states, including trauma, rupture of true aneurysms or AVMs, surgical and endovascular procedures, neoplasms, Marfan's syndrome, fibromuscular dysplasia, and vasculitis, which may lead to disruption of the arterial wall are possible causes of intracranial pseudoaneurysms1)4). Pseudoaneurysms of the cerebral arteries are reported very rarely.…”

ObjectiveThe spot sign on computed tomography angiography is little known about the relationship between the spot sign and the results of cerebral angiography We retrospectively analyzed the spot sign, digital subtraction angiography results, and other factors.Material and MethodsFrom December 2009 to May 2014, DSA was performed in 52 ICH patients with non-specific location or abnormalities on CTA findings. 26 of those patients, whose initial CTA showed the spot sign, were analyzed. Two groups, one with the spot sign in the ventricle (Group A) and others with the spot sign in another location (Group B) were statistically compared.ResultsThe mean age of the study subjects was 46.9 years (range, 15 to 80 years) and the percentage of males was 53.8%. Thirteen of 26 patients had ICH without intraventricular hemorrhage, and 6 patients had co-existing IVH. In 17 cases, the DSA results were negative. Seven patients were diagnosed with pseudoaneurysms, and two cases showed developmental venous anomalies. Group A consisted of the 8 patients (30.8%) who showed the spot sign in a ventricle. The number of pseudoaneurysms was statistically significantly higher in Group A than in Group B (71.4% versus 28.6%; OR, 13.3; 95% CI, 1.7-103.8 P = 0.014). All three patients who underwent endovascular treatment were members of Group A (P = 0.022), whereas most (92.3%) of those in Group B underwent surgical evacuation. (P = 0.030).ConclusionWhen CTA shows the spot sign in a ventricle, it is a clue that an existing underlying vascular lesion requires endovascular treatment.
