RESUMEN
The growth of a ruptured small saccular aneurysm has rarely been documented. Also rare are reports of spontaneous thrombosis of ruptured small intracranial saccular aneurysms. However, there are no reported instances of ruptured small saccular aneurysms that have demonstrated an increase in size after rupture, subsequently thrombosed and disappeared from circulation. We report one such aneurysm in a patient who presented with subarachnoid hemorrhage from a ruptured small saccular aneurysm of the anterior communicating artery. The possible reasons for the initial growth and subsequent thrombosis of the aneurysm from morphometric and flow dynamic points of view are discussed.

Absent circle of Willis (COW) has been described in cases of severe forms of cerebral developmental anomalies such as alobar prosencephaly. However, there are no reports of absent COW in patients with a milder form of cerebral abnormality such as colpocephaly. We report a unique case of an adult with colpocephaly and absent COW and discuss their association from a developmental perspective.
