Abstract:
A false aneurysm of the pericallosal artery formed following resection of a colloid cyst. The aneurysm presumably resulted from arterial damage during surgery and its enlargement may have been facilitated by the surgical defect in the corpus callosum. A spherical hyperdense lesion on postoperative CT may indicate a false aneurysm.
