“…[ 13 ] Second, we did not measure the concentrations of inflammatory cytokines either in the blood or cerebrospinal fluid. Finally, a bilateral frontal craniotomy together with resection of the falx cerebri may have provided a wider surgical field and better exposure of the aneurysm,[ 14 ] thus preventing postoperative perianeurysmal edema. We were concerned about his poor cardiac function; therefore, we performed a relatively small craniotomy and surgical exposure with the hope to shorten operation time.…”

We present a case of a partially thrombosed giant aneurysm of the pericallosal artery that experienced a temporary worsening of perianeurysmal edema after clipping. A 66-year-old man presented with progressive weakness of the right leg. Imaging studies revealed a partially thrombosed giant aneurysm at the bifurcation of the left pericallosal artery with concomitant perianeurysmal edema. The aneurysm was thought responsible for the symptoms of the patient, and he agreed to undergo clipping surgery. The aneurysmal neck was clipped using two long aneurysm clips without dissecting the aneurysmal dome. The patient woke up from anesthesia with the right-sided hemiparesis, which progressed to hemiplegia by 12 h after surgery. Brain computed tomography revealed worsening of the perianeurysmal edema. Fortunately, his symptoms resolved completely by 2 weeks after surgery with conservative management. Perianeurysmal edema is frequently observed in patients with partially thrombosed giant aneurysms. Although worsening of perianeurysmal edema is a relatively common complication of endovascular procedures, its occurrence after clipping has rarely been reported. The worsening may have been induced by release of inflammatory cytokines from aneurysm wall, which was rendered ischemic due to obliteration of the vasa vasorum by the clips. Perianeurysmal edema may develop or worsen after clipping of a partially thrombosed giant aneurysm if the interface between the aneurysm and surrounding brain is not fully dissected.

“…The azygos anterior cerebral artery (ACA) is a very uncommon anomaly of the circle of Willis with an incidence of 1–4%. [ 1 3 7 8 18 ] In this variant of normal embryogenesis, the confluence of both A1 segments results in the formation of a single distal ACA in the interhemispheric fissure. [ 1 3 8 ] This unique vascular configuration is frequently associated with saccular aneurysms and has significant impact on the arterial hemodynamics of the frontal lobe.…”

Background:The azygos anterior cerebral artery (ACA) is an uncommon intracranial vascular anomaly of the circle of Willis. Identification of aneurysm from azygos ACA with anterior falcine meningioma is an extremely rare association. The aim of the present study is to report the case of an adult female with a ruptured aneurysm from azygos ACA in association with an anterior falcine meningioma.Case Description:A 65-year-old female was admitted in the Emergency Department reporting sudden onset of severe headache. Computed tomography (CT) revealed an intracerebral hematoma and an expansive calcified lesion. AngioCT showed the presence of a large aneurysm in the distal portion of the azygos ACA. During the surgical procedure, it was possible to visualize the aneurysm in contact with an expansive lesion arising from the anterior third of the falx. Microsurgical clipping of the aneurysm was performed uneventfully and partial resection of the tumor was done. Histopathological analysis showed a fibrous meningioma. The patient was discharged home on the seventh postoperative day in good clinical conditions.Conclusion:The association of aneurysm from azygos ACA and falcine meningioma is an extremely rare event and must be remembered when expansive masses are present in the vicinity of vascular lesions.

“…The literature also provides a description of the coexistence of an azygos artery with corpus callosum hypoplasia, porencephalia, or vascular malformation [1][2][3][4]. In my own extensive (material subsequently treated by clipping and reviewed patients after subarachnoid haemorrhage within the last 10 years, no case of an azygos anterior artery A2 segment and coexisting giant aneurysm has been found.…”

“…This was the only case of a giant aneurysm located in the azygos pericallosal artery. In the literature of the subject only a handful of cases have been reported on the location and surgical treatment of giant aneurysm in azygos pericallosal artery [4,[6][7][8][9][10].…”
