Summary
This study reports an unusual intracranial extradural dermoid cyst in the lateral sphenoid ridge. Dermoid cysts should be considered in the differential diagnosis of lateral intracranial masses.
Area of Science:
- Neurosurgery
- Neuropathology
- Radiology
Background:
- Dermoid cysts are rare congenital tumors typically found at the midline and intradurally.
- Extradural and lateral dermoid cyst locations are exceptionally rare.
Purpose of the Study:
- To report an unusual case of an intracranial extradural dermoid cyst.
- To highlight the importance of considering dermoid cysts in the differential diagnosis of lateral intracranial masses.
Main Methods:
- A 53-year-old woman presented with headache and dizziness.
- Magnetic resonance imaging (MRI) and computed tomography (CT) revealed a mass at the right sphenoid ridge with bone erosion.
- Surgical resection via right pterional craniotomy was performed, followed by histopathological confirmation.
Main Results:
- An intracranial extradural dermoid cyst at the lateral sphenoid ridge was successfully resected.
- Histopathology confirmed the presence of a dermoid cyst.
- The patient experienced an uncomplicated postoperative recovery.
Conclusions:
- This case demonstrates that dermoid cysts can occur in extradural and lateral intracranial locations.
- Dermoid cysts should be included in the differential diagnosis for extradural and lateral intracranial masses.

01:27Cranial Bones: Lateral View
6.8K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
7.6K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:19Cranial and Spinal Meninges
4.5K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:22Sutures of the Skull
13.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:08Overview of the Skull
12.1K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:18Anatomy of the Brain: Ventricles
10.3K
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen.
