Anterior Communicating Artery Aneurysm With Refractory Central Vomiting: A Case Report

Anterior communicating artery aneurysm produces symptoms by compression of adjacent neural structures. It can cause nausea and vomiting because of direct compression or destruction of the hypothalamus. We described a 59-year-old man with refractory nausea and vomiting. He was evaluated completely for this problem yet no gastrointestinal pathology was found. Gastroenterologic examination was normal and he was referred to our center for neurological evaluation. We found anterior communicating artery aneurysm in his brain magnetic resonance imaging (MRI). This finding was confirmed by digital subtraction angiogram (DSA). It was decided to coil the aneurysm. After aneurysm embolization, the patient’s symptoms were surprisingly improved completely. We hereby report refractory vomiting as a rare presentation of un-ruptured anterior communicating artery aneurysm. This may be explained by a direct compressive effect of the aneurysm on adjacent structures.
