Abstract:
Meningiomas are meningothelial cell neoplasms that account for approximately 25% of all primary intracranial tumors. Most meningiomas are slow-growing benign lesions, and they are usually attached to the inner surface of the dura mater. Nevertheless, since the first description by of Cushing and Eisenhardt, many meningiomas without dural attachment have been reported. A subgroup located in the sylvian fissure (also called deep sylvian meningiomas) has been described, and these represent a radiological and neurosurgical challenge. We describe an atypical sylvian fissure meningioma in a 23-year-old male with a brief history of headache and mild hemiparesis. We also review the pertinent literature defining the major epidemiological, clinical, radiological and surgical characteristics of these rare tumors.
Insights
This study details an atypical sylvian fissure meningioma in a young male, highlighting the challenges these rare intracranial tumors present for diagnosis and treatment.
Area of Science:
- Neurosurgery
- Neuropathology
- Radiology
Background:
- Meningiomas are common primary intracranial tumors, typically benign and dural-based.
- A subset, sylvian fissure meningiomas, pose unique radiological and surgical challenges.
- These deep-seated tumors often lack typical dural attachment.
Observation:
- A case of an atypical sylvian fissure meningioma in a 23-year-old male is presented.
- The patient experienced headache and mild hemiparesis.
- This highlights the varied clinical presentation of these rare neoplasms.
Findings:
- Sylvian fissure meningiomas represent a distinct subgroup requiring specialized diagnostic and surgical approaches.
- Atypical features can occur even in younger patients.
- Literature review provides epidemiological, clinical, radiological, and surgical insights.
Implications:
- Improved understanding of sylvian fissure meningiomas aids in surgical planning and patient management.
- Early recognition of atypical presentations is crucial for effective treatment.
- Further research into the specific characteristics of these tumors is warranted.

01:22Sutures of the Skull
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...
01:14Cranial Bones: Superior and Posterior View
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,...
