Intracranial aneurysms are very rarely encountered during childhood. In the clinics, they may be revealed after non-specific complaints or they may be observed as subarachnoid hemorrhage triggered by trauma. Today, endovascular treatment option is more prominent for their management. In this study, we aimed to present a case that we hospitalized in our service due to head trauma and consequently detected a ruptured aneurysm. A fourteen-year-old male patient was admitted to our emergency room as intubated after falling from a chair in his father's workplace. After the brain computerized tomography and brain angiography, he was hospitalized with a pre-diagnosis of head trauma. The patient, who was treated for the existing brain edema, was extubated on the seventh day of hospitalization. The patient underwent digital subtraction angiography with the thought of presence of ruptured aneurysm in the images examined and a focus of aneurysm was detected in the right posterior inferior cerebral artery. The patient whose aneurysm sac was filled with gas by coil embolization technique during the same session was discharged on the 20th day of his hospitalization without brain edema and new focus of bleeding during his control computed tomography. We wanted to share this case study, in which we reviewed the literature about intracranial aneurysm treatment and follow-up options.
