Diagnosis: Benign vitreous hemorrhage
Vitreous hemorrhage is usually seen in the setting of diabetes which produces a proliferative vasculopathy and predisposes to hemorrhage. Ruptured intracranial aneurysm may also cause vitreous hemorrhage otherwise known as Tersons syndrome. Aneurysms associated with vitreous hemorrhage have included the anterior communicator, the internal cerebral artery and the middle cerebral artery. In the proper setting trauma is also an etiology for vitreous hemorrhage. Hemorrhage in the choroid or retina either from detachment or neoplasm may extend into the vitreous. In this case, the lack of abnormal enhancement makes underlying neoplasm less likely. The etiology for this patient's vitreous hemorrhage remained indeterminant.
