anterior cranial fossa

The anterior cranial fossa constitutes the floor of the cranial vault which houses the frontal lobes of the brain.

Gross anatomy

Structures present in the midline of the anterior cranial fossa from anterior to posterior are:

• groove for superior sagittal sinus
• groove for anterior meningeal vessels
• foramen cecum
• crista galli
  • provides attachment to falx cerebri
  • can contain marrow hence can be T1 hyperintense on MR
• slit and groove for nasociliary nerve
• anterior ethmoid foramen
• orifice for olfactory nerve
• posterior ethmoid foramen
• olfactory fossa

Boundaries

• anterior: cribriform plate of ethmoid bone, orbital plate of frontal bone, lesser wings and body of sphenoid bone
• posterior: lesser wings of sphenoid bone
