Nasal septal hematoma

Last revised by Mostafa Elfeky on 6 May 2021

Nasal septal hematomas arise from ruptures in the small blood vessels in the nasal septum and are largely secondary to trauma. The nasal septum has a rich vascular supply which sources from both the internal and external carotid arteries.

Septal hematomas appear as isoattenuating or hypoattenuating collections in the nasal septum. They can be uniform or heterogeneous in appearance and be found with or without nasal trauma.
