“…fails to provide a sufficient explanation for a higher incidence in other types of pituitary adenomas. [ 31 ] Thus, the exact cause of this peculiar peak in incidence remains unclear; however, it certainly raises concerns about the potential coexistence of an ICA aneurysm in the setting of an adenoma which may lead to hemorrhagic complications such as subarachnoid hemorrhage, carotid cavernous fistula, pituitary apoplexy, and intraoperative massive bleeding. [ 3 7 10 12 15 16 30 39 ] Therefore, a detailed assessment and review of the cerebral vasculature on presurgical MRI scans is required.…”

“…have found a higher incidence in aneurysm growth rate in patients suffering from GH-secreting tumors. [ 31 ] Assuming that the presence of these pathologies is a pure coincidence, and thus, managing it as an isolated condition is in contradiction to the aforementioned statements. However, in the absence of sufficient data and a scarcity of such reports in the literature, guideline-based management of incidentally discovered aneurysms should be considered.…”

Background:Currently, transsphenoidal surgery (TSS) is the preferred method for surgical treatment of intrasellar pituitary adenomas. However, it carries some risk of intraoperative arterial injuries, which is mainly attributed to direct iatrogenic rupture of the internal carotid artery (ICA). There is anecdotal evidence suggesting that intracranial aneurysms are coincidentally found significantly more frequently in the setting of pituitary adenomas than when the incidence is compared to other intracranial neoplasms. The exact cause of this discrepancy remains unclear, but it certainly raises concerns about the potential existence of an ICA aneurysm, which might be encountered during TSS and in some cases may cause hemorrhagic complications.Case Description:We present a case of a patient who was found to have a growth hormone (GH)-secreting pituitary adenoma and a coexisting cavernous ICA aneurysm which was embedded within the tumor. The patient underwent medical treatment of the adenoma. However, shrinkage of the tumor was associated with enlargement of the observed aneurysm, warranting endovascular intervention.Conclusions:This case report is an illustration for physicians to be conscientious about the potential danger posed by the coexistence of an intratumoral aneurysm in the setting of a pituitary adenoma. Special attention should be given to recognition of an intrinsic flow void signal on the presurgical imaging of the tumor, and if observed, magnetic resonance angiography (MRA) should be performed for preoperative planning. If MRA is not performed routinely, detailed review of high-resolution magnetic resonance imaging is recommended to detect any flow artifacts suggestive of an aneurysm.

A case report of the unilateral approach to the ruptured right ICA aneurysm together with tuberculum sella meningioma and left ICA aneurysm

Background: Tuberculum sellae meningioma associated with aneurysm is extremely rare with a limited number of individual cases previously reported. Because of the complicated anatomical structure of the skull base, comorbid disease in the sellae region is a challenging problem and is associated with high mortality in neurosurgery. Case presentation: This case report describes a rare case of comorbid bilateral internal carotid artery aneurysms and tuberculum sellae meningioma. This 58-year-old female presented with headache and nausea. She had lost her light perception in the right eye, and the right optic disc was degenerated. She also had a 5-year history of hypertension. This patient underwent a right pterional craniotomy, and we accomplished to clip the bilateral intracranial aneurysms and concurrently remove the tumor. After the surgery, we confirmed that both of the aneurysms were completely isolated, and the tumor was adequately resected. This patient had not suffered other neurological deficits. Unfortunately, her visual acuity had not recovered. Conclusions: As we know, this is the first report of a unilateral surgical approach to clip the bilateral intracranial aneurysms and concurrently remove the tumor. It may provide a reference for clinical treatment of the similar disease.

“…The prevalence of concomitant cerebral aneurysm and brain tumor is 0.3 to 7.7%. 8 9 Aneurysms are most commonly found in combination with meningioma, pituitary adenoma, and glial tumors, although there have been case reports of a combination with VS. 10 11 A combination of ICA extracranial stenosis and brain tumor is rare and has been described in the literature only as single cases. 12 …”

Surgery for Triple Pathology of Giant Vestibular Schwannoma Associated with Carotid Artery Stenosis and Intracranial Aneurysm: Case Report

et al. 2018

Here we report the case of a 56-year-old woman who presented with a highly unusual combination of three pathologies, namely a giant left-sided vestibular schwannoma, severe stenosis of the left internal carotid artery, and a right anterior cerebral artery aneurysm. The chosen approach comprised three consecutive surgical procedures, namely (1) aneurysm embolization, (2) carotid stenosis stenting, and (3) vestibular schwannoma excision. This approach avoided complications and achieved a satisfactory functional outcome. To the best of our knowledge, this combination of three conditions has not been previously reported in the English-language literature.
