Epistaxis

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Summary

Trauma-induced hemorrhage in the septum pellucidum, a rare brain injury, was identified 12 hours after head trauma. This finding is novel, as previous literature associated such bleeding primarily with tumors.

Area of Science:

Neurology
Trauma Surgery
Radiology

Background:

Hemorrhage within the septum pellucidum is typically associated with intracranial tumors.
Trauma-induced hemorrhage in this specific brain region has not been previously documented in existing literature.

Observation:

A patient presented with head trauma, initially showing no hemorrhage on immediate post-trauma imaging.
A subsequent brain tomography, conducted 12 hours post-trauma, revealed hemorrhage in the septum pellucidum.

Findings:

The delayed appearance of hemorrhage suggests a trauma-induced origin.
This case represents the first reported instance of septum pellucidum hemorrhage directly resulting from head trauma.

Implications:

This finding expands the spectrum of potential complications following head trauma.
It highlights the importance of serial neuroimaging in evaluating patients with head injuries, particularly when initial scans are negative.
