Abstract

We present a case of the simultaneous occurrence of spontaneous regression and de novo formation of intracranial aneurysm. A 50-year-old man was readmitted for headache and dizziness in April 2002, twelve years after the successful management of the subarachnoid hemorrhage(SAH) by clipping the ruptured left middle cerebral artery(MCA) aneurysm in September 1990. Angiograms obtained at that time also demonstrated the aneurysm on the right A1 segment, which was not treated. The follow-up cerebral angiograms demonstrated that the previously clipped aneurysm was not filled in, suggesting the successful treatment of the previous aneurysm. The left MCA stenosis was also detected. Notably, a new aneurysm developed at the right anterior communicating artery(ACoA) while the aneurysm at the right A1 segment which was not treated previously was markedly decreased in size.
