Giant aneurysm of the basilar artery presenting as a 3rd ventricular tumor is an unusual phenomenon. We are reporting a case in which a patient with a giant aneurysm of the basilar artery presented with symptoms of headaches and gait disturbance secondary to obstructive hydrocephalus. Although giant aneurysms presenting as mass lesions have been reported, the computed axial tomographic findings in our case were unique. Giant aneurysms of the basilar artery may be considered in the differential diagnosis of 3rd ventricular tumors.

    ABSTRACT: Between 1975 and 1989, 58 patients, 32 females and 26 males, mean age 50 years, with intracranial giant aneurysms with a diameter more than 2.5 cm were treated at our clinic. 48% of the patients presented with subarachnoidal hemorrhage. The most of the other 30 patients presented with cranial nerve dysfunctions. The most common site of the aneurysm was the internal carotid artery (25 cases, 43%), followed by the anterior cerebral artery (14%), and the vertebro-basilar region (11 cases, 19%). In 14 patients direct surgery was not performed because of the poor general condition of the patient, the high risks, or non-consent. In seven patients (12%) the aneurysm had been misdiagnosed as meningeoma, pituitary-adenoma, craniopharyngeoma or glioblastoma. 47% of all patients were discharged as "independent" and 19% died. Patients without SAH had better chance of survival: 7% of patients without SAH died and 29% of patients with hemorrhage. 50% of patients without hemorrhage were discharged as "independent" but only 18% of patients with SAH. Because of the high incidence of hemorrhage and the better prognosis for patients without hemorrhage, we recommend routine surgical treatment of patients with giant aneurysms.

    ABSTRACT: A new approach to the basilar apex in a patient with a megadolichobasilar anomaly and an abnormally rostral basilar apex aneurysm is described. The details of the surgical approach and the advantages and limitations of this transcallosal, interseptal approach are described.

    ABSTRACT: Intracranial giant aneurysms have been considered to grow by recurrence of intramural hemorrhage of the aneurysmal wall. However, it remains uncertain whether rupture of giant aneurysms is brought about by the same mechanism that causes the rupture of smaller saccular aneurysms. It is also unclear whether intramural hemorrhage is correlated with the rupture of giant aneurysms. A 67-year-old woman was admitted with symptoms of gait disturbance and dementia. Computed tomographic scans revealed a large mass located in the prepontine region and extending into the third ventricle as well as moderate dilatation of the lateral ventricles. Angiography demonstrated a giant basilar tip aneurysm and multiple aneurysms located in the bilateral anterior and middle cerebral arteries. Ventriculoperitoneal shunting was scheduled, but subarachnoid and intraventricular hemorrhage occurred and the patient died. Computed tomographic scans, performed immediately before the disastrous hemorrhage, displayed intramural hemorrhage in the wall of the giant basilar tip aneurysm. Ventricular drainage was performed, but the patient died. It seems probable that intramural hemorrhage of the aneurysmal wall may cause both the growth and rupture of intracranial giant aneurysms.
