Fourteen-Year-Old Boy With Intracranial Internal Carotid Artery Aneurysm Presenting as Mood Disorder.

Intracranial aneurysms (IA) are very uncommon to find in the pediatric population. If present, it is usually associated with other genetic illnesses. Most of the intracranial aneurysm has been presented due to mass effect of the aneurysm or as subarachnoid hemorrhage. We report this young Asian kid who has had a possible ictus of subarachnoid hemorrhage (SAH) with depressive symptoms, later presenting with classic features of SAH due to rupture of intracranial internal carotid artery aneurysm. The use of Sertraline to treat depressive episodes may aggregate the condition due to its antiplatelet effect. The patient showed significant improvement following microsurgical clipping of the aneurysm. This case is another example that young patients coming with the first episode of mood disorder should be carefully excluded for other intracranial pathology, including intracranial aneurysms, before coming to the final diagnosis.
