Extradural hematoma from trauma to midline skull tumour

Area of Science:

• Neurosurgery
• Oncology
• Pathology

Background:

• Malignant tumors invading dural venous sinuses pose risks for intracranial hemorrhage.
• Plasma cell tumors are rare neoplasms that can affect various body systems, including the skull base and venous sinuses.

Observation:

• A patient with a plasma cell tumor invading the superior sagittal sinus sustained an extradural hematoma after a minor head injury.
• Emergency craniotomy and hematoma evacuation were performed.

Findings:

• Direct repair of the eroded superior sagittal sinus was impossible due to tumor invasion.
• A novel surgical technique involved using the dura to reconstruct the sinus wall, reinforced with hemostatic agents.

Implications:

• This case highlights the potential for life-threatening bleeding from dural venous sinus invasion by tumors, even after minor trauma.
• The presented surgical approach offers a viable solution for managing complex sinus injuries where direct repair is not feasible.
