[Two cases of pericranial sinuses (author's transl)]

Area of Science:

• Neurosurgery
• Vascular Surgery
• Radiology

Background:

• Sinus pericranii is a rare vascular tumor connecting the intracranial venous system with extracranial veins.
• Accurate diagnosis and surgical planning are crucial for managing these complex lesions.

Observation:

• Two cases of sinus pericranii are presented.
• A decrease in tumor size when patients assumed a sitting position was noted, aiding clinical diagnosis.
• External carotid angiography was normal in both cases.

Findings:

• Direct contrast medium injection into the tumor enhanced X-ray diagnosis by visualizing venous outflow into meningeal veins.
• This technique differentiated sinus pericranii from other skull tumors.
• Gradual coagulation of feeding vessels facilitated bloodless surgical excision.

Implications:

• Positional changes and targeted contrast-enhanced X-rays are valuable diagnostic tools for sinus pericranii.
• A stepwise approach to vessel coagulation allows for safe and effective surgical resection.
• Improved diagnostic and surgical strategies can lead to better patient outcomes for rare vascular skull tumors.
