Insights

Intradiploic meningioma, a rare brain tumor, can grow large and extend into the orbit. This case highlights successful surgical removal and reconstruction for a giant sphenotemporal intradiploic meningioma.

Area of Science:

  • Neurosurgery
  • Oncology
  • Skull Base Surgery

Background:

  • Intradiploic meningiomas represent a rare subtype of meningioma, comprising approximately 1% of all diagnosed cases.
  • These tumors arise within the diploë of the skull, differentiating them from typical meningiomas.
  • Giant meningiomas pose unique surgical challenges due to their size and potential for extensive invasion.

Observation:

  • A rare case of a giant sphenotemporal intradiploic meningioma with significant orbital extension was observed.
  • The affected patient was a 27-year-old female presenting with symptoms related to the tumor's mass effect and extension.
  • Diagnostic imaging revealed the large tumor size and its involvement of the sphenotemporal region and orbit.

Findings:

  • Complete surgical excision of the giant sphenotemporal intradiploic meningioma was achieved.
  • The surgical defect required bony reconstruction, successfully managed with an autologous split-thickness bone graft.
  • Histopathological analysis confirmed the diagnosis of intradiploic meningioma.

Implications:

  • This case demonstrates the feasibility of radical surgical management for complex, large intradiploic meningiomas with orbital invasion.
  • Successful bony reconstruction using autologous grafts is crucial for restoring structural integrity and cosmesis.
  • Further research into the optimal management strategies for rare and giant meningiomas is warranted.

Primary Active Transport01:47

Primary Active Transport

In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Primary Production01:06

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Primary Distribution01:28

Primary Distribution

Primary distribution systems deliver electrical power from substations to consumers through various voltage classes, with 15-kV class voltages being predominant among U.S. utilities. Older 2.5- and 5-kV classes are being replaced by 15-kV primaries, while higher 25- to 34.5-kV classes are used in high-density urban areas and rural regions with long feeders. Three-phase, four-wire multigrounded systems are widely employed for balanced power delivery, using the neutral wire as a grounding point.

Nomenclature of Primary Amines01:17

Nomenclature of Primary Amines

Primary, secondary, and tertiary amines are compounds consisting of one, two, and three alkyl groups connected to the amino group (–NH2), respectively. As depicted in Figure 1, the common name of the primary amines is obtained by adding the suffix -amine to the alkyl substituent attached to the amino group as the corresponding alkylamine.
