Spontaneous regression of an unruptured aneurysm is very rare. We present a case of a 64-year-old woman with an unruptured cerebral aneurysm in which spontaneous regression occurred after contralateral clipping. High-resolution magnetic resonance imaging showed that the aneurysm had decreased in size and there was no evidence of thrombus. Level of Evidence Case, Level IV.
Case Details
Disease Location
Right anterior temporal artery
Personal Characteristics
64-year-old woman, treated for hypertension for 7 years
Clinical Characteristics
Underwent mra at another institution to evaluate chronic headaches with intermittent and fluctuating characteristics that had persisted for 1 month. Cerebral angiography revealed multiple aneurysms involving the anterior communicating artery (acom) (3 mm); the right anterior temporal artery (2.2 mm); and the left mca bifurcation (1.8 and 2.6 mm). The left mca aneurysms were successfully treated with clipping. The acom aneurysm was treated with endovascular coiling 1 year after the initial surgery
Remission Characteristics
One year after surgery, a follow-up angiography showed that the right anterior temporal artery aneurysm had regressed
Treatment & Mechanisms
Proposed Remission Mechanisms
None reported
Clinical Treatment
Clipping, coiling
Non-Clinical Treatment
None reported
