We report two cases of true posterior communicating artery (Pcom.) aneurysms. The first case was a 73-year-old female who presented with a sudden onset of headache and was diagnosed to have a subarachnoid hemorrhage. Angiography and three-dimensional computed tomography angiography (3D-CTA) demonstrated a Pcom aneurysm. The intraoperative findings showed the presence of a true Pcom aneurysm. The second case was a 61-year-old female who presented with a headache and was diagnosed with an unruptured aneurysm. Angiography demonstrated an IC-Pcom aneurysm and a true Pcom aneurysm. The intraoperative findings showed that the true Pcom aneurysm was located at the branching site. Both cases were successfully clipped. A careful preoperative diagnosis and intraoperative investigation are important for ensuring the correct treatment of such cases. We also discuss the pathogenesis of true Pcom aneurysms, and the advantages and pitfalls of the surgical treatment of true Pcom aneurysms.
