Abstract
Many cases of an intracranial aneurysm associated with a polycystic kidney disease (PKD) are found in the literature, but only 30 domestic cases have been reported. Herein, the authors report a recent case of an intra-cranial aneurysm that was complicated by PKD. A neck clipping of the aneurysm was performed but a postoperative CT scan showed intracerebral hemorrhage. They thus investigated the patient's family for signs of PKD. Her daughter was diagnosed as having a PKD, but no intracranial aneurysms were found on MR angiography. The authors emphasize the importance of detecting possible intracranial aneurysms in PKD patients, since the rupture of an aneurysm could prove critical. In the management of cerebrovascular disorders, including intracerebral hemorrhage, it is necessary to detect any associated PKD, especially at the time of operation. Also, extreme care must be taken since the blood vessels of PKD patients are very fragile.
