Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

4.8K
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...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.9K
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...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

8.6K
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,...

Sutures of the Skull01:22

Sutures of the Skull

14.2K
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...

Area of Science:

  • Neurosurgery
  • Oncology
  • Pathology

Background:

  • Intracranial chondromas are rare, benign cartilaginous tumors, accounting for approximately 0.2% of all brain tumors.
  • Typically found at the skull base, they originate from embryonic chondrogenic cells.
  • Rarely, they can arise from the dura, falx cerebri, or brain parenchyma.

Observation:

  • This report details a rare case of a dural-based intracranial chondroma.
  • The presentation focuses on the technical challenges and considerations for surgical resection.

Findings:

  • The study reviews current literature on intracranial chondromas, covering incidence, origin, symptoms, imaging, histopathology, and prognosis.
  • Dural-based chondromas, though rare, require specific surgical approaches.

Implications:

  • Understanding the nuances of dural-based chondromas is crucial for neurosurgeons.
  • This review aids in optimizing surgical strategies and patient outcomes for rare intracranial tumors.
