Summary
Sinus pericranii, a rare vascular anomaly, can present after head trauma but may have congenital origins. This case highlights diagnostic challenges and surgical removal of the frontal sinus pericranii.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Sinus pericranii is a rare vascular malformation connecting extracranial and intracranial circulation.
- Distinguishing congenital versus acquired causes can be challenging.
Observation:
- A case of frontal sinus pericranii developed two years post-head trauma.
- Pathological examination revealed vascular endothelium, suggesting a congenital etiology.
- The anomaly was associated with a persistent trigeminal artery.
Findings:
- Detailed imaging findings from CT, angiography, and MRI are presented.
- Surgical excision of the lesion, pericranial blood sinuses, and involved bone was successful.
- Literature review and discussion on the pathogenesis of sinus pericranii.
Implications:
- This case underscores the importance of thorough pathological and radiological evaluation for accurate diagnosis.
- Understanding the congenital basis of sinus pericranii informs surgical planning and prognosis.
- Further research into the pathogenesis may reveal new insights into vascular development.
