Abstract
It is well known that autosomal dominant polycystic kidney disease is very frequently accompanied by intracranial aneurysm. We used magnetic angiography (MRA) screening to facilitate early detection of such unruptured intracranial aneurysm. Consequently, 6 lesions suspected of being intracranial aneurysms were found in 23 patients. Of these, excluding two patients, one of whom did not give consent and one of whom was pregnant, 4 patients underwent angiography and 4 intracranial aneurysms ranging from 4 to 8mm were found in the vertebral artery, bifurcation of internal carotid and ophthalmic artery respectively and 2 aneurysms were found in the middle cerebral artery. Clipping surgery and embolization were performed in 2 patients and one patient, respectively. MRA, a noninvasive method, was useful in screening for intracranial aneurysm.
