Sinus pericranii, a rare skull and venous sinus communication, can cause symptoms like headaches. Diagnosis involves imaging, with treatment ranging from observation to surgery based on size and flow.

Area of Science:

  • Neurology
  • Vascular Malformations
  • Neurosurgery

Background:

  • Sinus pericranii is a direct communication between the skull's outer surface and intracranial venous sinuses.
  • This congenital, acquired, or traumatic abnormality is typically midline and frontal, often asymptomatic but can cause headaches, nausea, and vertigo.

Purpose of the Study:

  • To present four cases of sinus pericranii.
  • To discuss the diagnostic imaging modalities and therapeutic approaches for sinus pericranii.

Main Methods:

  • Review of four clinical cases of sinus pericranii.
  • Analysis of diagnostic findings from radiography, CT, MRI, and angiography.
  • Evaluation of treatment outcomes based on lesion characteristics and patient symptoms.

Main Results:

  • Sinus pericranii presents as a fluctuating, non-pulsatile mass, often with associated bone defects visible on CT.
  • Imaging can delineate the vascular communication, with MRI indicated for complex cases or suspected intracerebral abnormalities.
  • Direct contrast injection confirms diagnosis and assesses flow rate, guiding therapeutic decisions.

Conclusions:

  • Treatment strategies for sinus pericranii vary from observation for small, asymptomatic cases to endovascular sclerosis or surgical removal for larger or symptomatic lesions.
  • Surgical removal is often straightforward for sinus pericranii.
  • Accurate diagnosis and flow assessment are crucial for effective management of sinus pericranii.
