(a and b) Native computed tomography (CT) scan. Subarachnoid-parenchymal hemorrhage associated with development of the intracerebral hematoma in the interhemispheric fissure and the left cortex. (c-e) CT-angiography. In the area of the A1-segment of the right anterior cerebral artery - is an extended fusiform aneurysm in the distal A1-segments (arrow); 6.6 mm in diameter at widest part of fusiform aneurysm and a length of about 10.4 mm.

CT-angiography revealed the right sided FA on the A1-segment of ACA, basal SAH, intracerebral hematoma in the mediobasal frontal lobe and in the interhemispheric fissure [Figure 1]. Cerebral angiography performing was associated with a high risk of rebleeding and patient's condition worsening.
(a and b) A microsurgical clipping stages of the eccentrically fusiformed part of the aneurysm of the A1-segment of the right part of the anterior cerebral artery (ACA), (1) A1-segment of the ACA, (2) the right optic nerve, (3) the recurrent artery of Heubner, A - aneurysm. (c and d) Postoperative changes on native computed tomography (CT)-scan. (e and f) CT-angiography shows that the aneurysm was clipped. The ipsilateral A1 segment of the right ACA is conserved (arrows).
