We report a case of spontaneous disappearance and recanalization of ruptured pericallosal artery aneurysm. A patient in her 40s presented with semicomatose mentality and massive intraventricular hematoma. Initial computed tomography angiogram (CTA) showed definite saccular aneurysm on pericallosal artery. But, cerebral angiography while attempting urgent coil embolization showed disappearance of the ruptured aneurysm along with thrombotic occlusion of parent artery. Then, the patient had been receiving conservative management in the intensive care unit. The CTA was repeated on hospitalization day (HD) 7 and 14. Recanalization was detected on CTA of HD 22. The ruptured aneurysm was obliterated with endovascular coiling on the HD 23. The aneurysm has been stable for 36 months. Careful surveillance for recanalization followed by delayed intervention will be crucial in the exceptional situations of a spontaneously disappearing aneurysm.
