Giant arachnoid granulations can cause symptoms by obstructing dural sinuses. However, pressure measurements in this case excluded the granulation as the cause of headaches, suggesting medical treatment was appropriate.

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Arachnoid granulations are typically incidental findings.
  • Giant arachnoid granulations can rarely cause symptoms like venous hypertension due to dural sinus obstruction.

Observation:

  • A 31-year-old man presented with a 3-month history of progressive bifrontal headaches.
  • A giant arachnoid granulation was identified at the posterior superior sagittal sinus.

Findings:

  • Intrasinus pressure measurements revealed no significant pressure difference across the granulation.
  • The headaches were treated medically, implying the granulation was not the primary cause.

Implications:

  • Dural sinus pressure measurements can help exclude giant arachnoid granulations as a cause of symptoms.
