Decreased volume of the left anterior cranial fossa
is visible on all three images.
5 Nasal encephaloceles are anterior encephaloceles where meningeal herniation occurs through a midline defect in the floor of the anterior cranial fossa
Brain magnetic resonance imaging (MRI) revealed a mass at the anterior cranial fossa
in the midline, in front of the lateral ventricles with compression of the third ventricle of the brain.
Ruptured anterior communicating artery aneurysm associated with anterior cranial fossa
dural arteriovenous fistula--case report.
Skull base coronal thin-section CT scan showed a fracture in the right side of ethmoid plate, and MR cisternography revealed high-signal-intensity CSF column in the right side of the floor of anterior cranial fossa
and sinus [[Figure 1]-case 2].
The carotico-clinoid foramen is an inconstant structure, which is located in the anterior cranial fossa
composed by the ossification of a fibrous ligament (1) that begins on the anterior clinoid process and binds to the middle clinoid process.
In decreasing order of prevalence, SNTCSs are also found in the orbit, skull base, cribriform plate, nasopharynx, and anterior cranial fossa
Erosions of both medial orbital walls were noted along with evidence of extradural extension into the anterior cranial fossa
via the posterior wall of left frontal sinus.
Diagnostic imaging identified a large JNA (Radkowski (6) stage IIIb and Fisch (7) stage IVb) that extended into the nasal cavities, sphenoid sinus, right maxillary sinus, clivus, pterygoid fossa, anterior cranial fossa
, and right middle cranial fossa abutting the temporal lobe (figure 1, B).
A vascularized local pericranial graft is effective in the prevention of anterior cranial fossa
Magnetic resonance imaging (MRI) revealed extension of the mass into the extradural anterior cranial fossa
(figure 1, B).
Orbital branches of middle meningeal artery passing through cranioorbital foramen is thought to be main vascular supply to meningiomas in the anterior cranial fossa
as indicated by Kuru (1967).
High-resolution computed tomography (CT) of the anterior cranial fossa
demonstrated air in the cranial cavity, indicating a fracture or breach of the cribiform plate (figure 1).
Invasion of the Dura and the anterior cranial fossa
is seen in 25% of the cases.
Computed tomography (CT) of the sinuses demonstrated a large, enhancing mass within the left ethmoid sinus; CT also showed tumor erosion through the anterior cranial fossa
and the left lamina papyracea and compression of the medial rectus muscle and optic nerve (figure 1).
