KEY LEARNING POINTS:
A 43-year-old man presents with a 4-day history of a constant headache. Initial CT Head demonstrates very small Hunt Hess Grade 1 supra-sellar Subarachnoid Hemorrhage (SAH), prompting cerebral angiography, which confirmed complex wide-neck anterior communicating artery aneurysm (Figure 1. A. NCT B. Lateral DSA C. 3-D DSA Recon). He underwent open microsurgical clipping of the aneurysm with preservation of the parent vessels and complete obliteration of the aneurysm (Figure 3. A. Lateral DSA B. 3-D DSA Recon). After monitoring and critical care management for SAH, he made a complete functional recovery, returning to all activities of daily living.
