Dural Venous Sinus Thrombosis: A Rare Cause of Intracranial Hemorrhage.

Dural venous sinus thrombosis, a subset of cerebral venous thrombosis, is an important pathology due to its significant morbidity and mortality. This process has an annual incidence of three to five cases per million adults. Although copious predisposing factors exist, the core principles revolve around Virchow's triad: venous stasis, hypercoagulability, and vascular endothelial damage. There are various risk factors related to unfavorable outcomes, which include female sex, intracranial hemorrhage, infection, cancer, and more. Trauma tends to be a risk factor, particularly in pediatric populations, as in this patient's case. Initial diagnosis in the acute setting commonly involves non-contrast CT studies to exclude hemorrhage. In subacute or chronic settings, MRI can be utilized. Anticoagulation remains the mainstay of therapy for treatment, along with treating any underlying causes of thrombosis. We present a pediatric patient with extensive post-traumatic dural venous sinus thromboses with classic imaging findings as well as full resolution of clinical symptoms after this pathologic process was recognized and treated appropriately.
