Vessel Wall Imaging in Angiogram-Negative Diffuse Subarachnoid Hemorrhage Reveals a Ruptured Lenticulostriate Aneurysm.

A patient presented with acute onset headache and subsequent unconsciousness. The neurologic exam showed left-sided myoclonic jerking and right flaccid hemiparalysis. Noncontrast computed tomography revealed diffuse subarachnoid hemorrhage (SAH) with acute hydrocephalus. Initial digital subtraction angiography (DSA) showed no culprit source for SAH. Repeat DSA on day 7 after initial presentation raised suspicion for left internal carotid artery ophthalmic segment and left lateral lenticulostriate artery (LSA) aneurysms. A magnetic resonance vessel wall imaging (VWI) exam was performed given the presence of multiple potential culprit aneurysms. Vessel wall enhancement around the dome of the left LSA aneurysm suggested rupture, which then facilitated treatment with surgical clipping. LSA aneurysms are exceedingly rare and challenging to treat. Given the associated high degree of morbidity, expedient diagnosis is critical to direct management. VWI could be a valuable tool for detecting ruptured aneurysms in the setting of angiogram-negative SAH.

Partially thrombosed middle cerebral artery-lenticulostriate artery aneurysm with native radiological examinations suggesting proximal lenticulostriate artery aneurysm: A case report

Background: Preservation of the lenticulostriate artery (LSA) is crucial. LSAs usually cannot be spared with LSA aneurysms, when surgical clipping/excision or endovascular embolization of the LSA itself is performed. On the other hand, the LSA should be separated and preserved for proximal middle cerebral artery (M1)-LSA aneurysms.Case Description: We report a case of M1-LSA aneurysm with native radiological examinations suggesting LSA aneurysm. The highlight of this unusual case was that during surgery, the aneurysm orifice was almost covered with thrombus and blood flow in an aneurysm that appeared separate from M1. Partial thrombectomy-clip reconstruction was performed, and M1 and LSAs were well preserved.Conclusion: Even with currently developed radiological modalities, thrombosed intracranial aneurysms may be misdiagnosed, depending on intraluminal flow conditions. Intraoperative findings from craniotomy sometimes contribute to a better understanding of the pathophysiology and decisions on appropriate treatment strategy.

Charcot-Bouchard Aneurysm Diagnosed with CTA and MRA

Hemorrhage in the basal ganglia resulting to lenticulostriate artery aneurysm rupture is extremely rare. This distal micro-aneurysm of the perforating lenticulostriate arteries is called Charcot-Bouchard aneurysm. We wish to report a case of an hematoma in the basal ganglia due to a Charcot-Bouchard aneurysm demonstrated by Computed Tomography Angiograpy (CTA) and Magnetic Resonance Angiography (MRA) and confirmed by selective catheter angiography.Teaching Point:Charcot-Bouchard aneurysm is a very rare distal micro-aneurysm of the perforating lenticulostriate arteries. Young patients who experience basal ganglia hemorrhage should have contrast-enhanced CT, especially if they don’t have arterial hypertension and if subarachnoid hemorrhage is associated.

Post-thrombolysis rupture of small lenticulostriate aneurysms: A report of 2 consecutive cases

The 2018 American Heart Association/American Stroke Association (AHA/ASA) guidelines stated that the administration of intravenous recombinant tissue-type plasminogen activator (rTPA) for acute ischaemic stroke is probably safe for patients with small (i.e. <10 mm) unruptured intracranial aneurysms. We present 2 cases of small (2 and 5 mm) lenticulostriate artery (LSA) aneurysms which ruptured immediately following rtPA infusion. The ensuing acute intracranial haemorrhages resulted in the death of one patient and severe functional impairment for the other. Given the limited literature available, the natural history of LSA aneurysms is largely unknown. This report suggests that LSA aneurysms, regardless of size, be considered separately from other conventional aneurysms as “high-risk” lesions and a contraindication to thrombolysis.

Surgical treatment of lenticulostriate aneurysms (a case report and literature review)

The study objective is to describe a rare case of putaminal intracerebral hemorrhage (PICH) results from a rupture of the distal lateral lenticulostriate artery (LSA) aneurysm and to summarize currently available information on its diagnosis and treatment.Materials and methods. A 40-year-old female patient was admitted to the N.V. Sklifosovsky Research Institute of Emergency Medicine. Her arterial pressure was 200/110 mm Hg. Brain computed tomography (CT) revealed a 25 сm3 right-sided PICH with a minimal perifocal edema. CT angiography revealed a saccular aneurysm located in the right distal LSA with the dome of 5 mm and the neck of 2 mm. We performed right frontotemporoparietal osteoplastic craniotomy and used the transsylvian transinsular approach to PICH represented by ruptured while we were removing the blood clots. We performed aneurysm trapping and removed the hematoma.Results. This clinical case demonstrates the possibility of successful microsurgical repair of the distal lateral LSA aneurysm rupture. Six months postoperatively, the patient had complete regression of left leg paresis and partial restoration of left hand functions.Conclusion. This case report appears quite interesting since deep intracerebral hematomas of this etiology are extremely rare. An optimal treatment for LSA aneurysms remains a subject of debate due to the small number of patients with this disorder and limited data on it. Patients with fusiform aneurysms require conservative treatment and dynamic follow-up with periodic cerebral angiography. Patients with typical saccular aneurysms or PICH presenting mass effect should undergo surgical treatment.

Embolization of Ruptured Distal Lenticulostriate Artery Aneurysms

To describe the critical role of endovascular treatment and safety for the patients who presented with intraventricular hemorrhage owing to rupture of the distal lenticulostriate artery aneurysms. Three patients who underwent endovascular treatment for distal lenticulostriate artery aneurysms related to intraventricular hemorrhage were selected and retrospectively reviewed. Patients were treated successfully using endovascular embolization without any complications. Endovascular therapy is available and safe as a treatment option for distal lateral lenticulostriate artery aneurysms.

Lenticulostriate Artery Aneurysm Associated with Cerebral Arteriovenous Malformation: Report of Rare Association and Its Endovascular Management

AbstractAneurysms involving the lenticulostriate arteries are rare and are described in the literature in small case series or single-case reports. In this report, we discuss a case of a young woman who presented with acute lateral ventricular bleed and was found to have an arteriovenous malformation within the corona radiata and an aneurysm involving the distal lenticulostriate artery. The aneurysm was treated successfully by endovascular embolization. In deep-seated arteriovenous malformations (AVMs) that are conventionally treated by stereotactic radiosurgery, a targeted approach for treatment of an associated aneurysm could be considered to reduce the risk of rebleed until the AVM is obliterated.

Intracranial Aneurysms Associated with Moyamoya Disease in Children: Clinical Features and Long-Term Surgical Outcome

Moyamoya disease (MMD) in children was rarely associated with intracranial aneurysms. The purpose of this study was to report the clinical characteristics and long-term surgical outcomes of pediatric intracranial aneurysms accompanied with MMD. Between October 2002 and October 2013, our department treated 9 pediatric MMD patients (aged ≤17 years) with intracranial aneurysms. Clinical and angiographic features, treatment selection, as well as follow-up information were obtained and analyzed. The efficacy of vascularization and the changes of intracranial aneurysms were evaluated with digital subtraction angiography (DSA). We also collected 7 previously published reports to analyze the characteristics of this rare condition. In our series of 9 patients, 7 were male. The mean age was 11 ± 3.4 years (range 5-16). Seven patients presented with intracranial hemorrhage as the initial manifestation, while 2 patients suffered transient ischemic attacks. The most common aneurysm location was the posterior choroidal artery (4, 44.4%). One anterior choroidal artery aneurysm was completely embolized with Onyx (ev3, Irvine, California, USA). One posterior choroidal artery aneurysm failed due to inaccessibility to the parent artery. Bilateral encephalo-duro-arterio-synangiosis (EDAS) surgery was performed for all the children. During the follow-up period of 6.4 ± 2.2 years (range 3-11), spontaneous occlusion of aneurysm was observed in 4 children, including 1 child with middle cerebral artery aneurysm, 1 with lenticulostriate artery aneurysm, and 2 with posterior choroidal artery aneurysm. Good or fair vascularization was observed in all the 9 children with DSA follow-up. No patients suffered intracranial hemorrhage during the follow-up period. The long-term survey showed EDAS surgery could effectively increase the cerebral blood flow and maintain good outcomes in children, which may further result in the disappearance of the intracranial aneurysms and decrease the incidence of recurrent hemorrhage.

Idiopathic Lenticulostriate Artery Aneurysm in an Adolescent Presenting with Intracerebral Hemorrhage

We describe a rare case of idiopathic lenticulostriate artery (LSA) aneurysm in a 15-year-old girl who presented in the emergency department with a sudden onset of severe headache and left hemiparesis. Computed tomography revealed an intracerebral hemorrhage in right basal ganglion. Angiography revealed a LSA aneurysm. The patient underwent right frontal craniotomy for aneurysm removal. Overall, the patient experienced a positive outcome after surgery for a ruptured LSA aneurysm. Following the operation, the patient participated in a 1-week rehabilitation program, which improved her left hemiparesis. We observed a positive outcome with surgical treatment for the ruptured LSA aneurysm, which was probably improved by early surgical intervention.

Lenticulostriate Artery Aneurysm Presenting as Subarachnoid Haemorrhage

Lenticulostriate perforating artery aneurysms are rare [1]. Lenticulostriate artery (LSA) aneurysms are endarteries, small and fragile and supply internal capsule and basal ganglia and LSA aneurysms may be saccular or fusiform and commonly present with basal ganglia hemorrhage [1,2]. They can be associated with conditions like moyamoya disease, hypertension, vasculitis and arterio-venous malformations (AVMs) [1-4]. LSA aneurysms which by itself is an uncommon entity usually presents with intraparenchymal haemorrhages [3,5]. Rarely LSA aneurysms presents with subarachnoid haemorrhage (SAH) or primary intraventricular haemorrhage PIVH [1-3,5,6]. We report a rare case of LSA aneurysm presenting with SAH who was successfully managed conservatively.
