Abstract
Objective: We present a case of ruptured anterior communicating artery (Acom) aneurysm on the tuberculum sellae, treated with coil embolization.
Case presentation: A 63-year-old man suffered consciousness loss and was admitted to our hospital. CT revealed a subarachnoid hemorrhage. Three-dimensional CT angiography (3D-CAT) revealed a tiny aneurysm located at the Acom on the tuberculum sellae. Coil embolization of the aneurysm was performed because we thought that it would be difficult to identify the aneurysmal neck during clipping surgery.
Conclusion: Acom aneurysm located on the tuberculum sellae is very rare. 3D-CTA is very useful for understanding the anatomy and deciding the treatment method. Considering the location of the aneurysm, coil embolization may be a better treatment than clipping.
