Anterior communicating artery aneurysm in a young patient with Fahr’s disease: case presentation

Background and importance: Fahr disease is an uncommon disorder defined as prominent calcification in basal ganglia, dentate nuclei of cerebellum, pulvinar thalami and subcortical white matter and it has been shown that calcium is the major factor that causes the hyperdensity on computer tomography (CT). Spontaneous subarachnoid hemorrhage from an aneurysm in a patient with Fahr disease was first reported by Al-Jehani et al. in 2012 in a 54-year-old female patient with calcification of basal ganglia and deep cerebellar nuclei and a subarachnoid hemorrhage from a right posterior communicating artery aneurysm. Clinical presentation: We present a 17 years old patient with Fahr disease with an anterior communicating artery aneurysm rupture. Conclusion: There are few reports of intracranial hemorrhage with Fahr’s disease. It may be suggested that excessive calcium accumulation contributes to aneurysm formation or rupture.
