Summary
Chordoid meningiomas are rare, aggressive WHO grade II tumors. This case highlights an extremely rare orbital chordoid meningioma in an elderly male presenting with orbital swelling.
Area of Science:
- Neuro-oncology
- Ophthalmology
- Pathology
Background:
- Chordoid meningiomas are rare WHO grade II tumors, accounting for 0.5% of all meningiomas.
- These tumors are known for their aggressive nature and high local recurrence rates.
Observation:
- A rare case of orbital chordoid meningioma was observed in a 77-year-old male.
- The patient presented with a painless, progressive swelling on the right lateral orbital wall.
Findings:
- The case represents an extremely rare presentation of chordoid meningioma in the orbit.
- This highlights the diagnostic challenge due to the rarity of orbital chordoid meningiomas.
Implications:
- Further research is needed to understand the behavior and treatment of orbital chordoid meningiomas.
- Early diagnosis and management are crucial for improving patient outcomes in rare orbital tumors.

01:19Cranial and Spinal Meninges
1.7K
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...

01:27Cranial Bones: Lateral View
2.4K
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
2.6K
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,...

01:26Arteries of the Head and Neck
1.6K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:22Sutures of the Skull
7.3K
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...

01:19Cranial Nerves: Overview and Anatomy
2.2K
The cranial nerves are an important part of the complex network of nerves in the human body. These nerves emerge directly from the brain and are responsible for transmitting essential information between the brain and various parts of the head and neck. There are 12 pairs of cranial nerves, systematically numbered using Roman numerals from I to XII, beginning from the anterior and moving to the posterior of the brain. Each cranial nerve is uniquely identified by names that reflect its function...
