Solitary pulmonary metastasis from intracranial meningiothelial meningioma

Area of Science:

• Neurology
• Oncology
• Pulmonology

Background:

• Benign intracranial meningiomas are common primary brain tumors.
• Metastasis from these tumors is exceptionally rare, especially to the lungs.

Observation:

• A case of meningothelial meningioma with a solitary pulmonary deposit is presented.
• Histological confirmation of the pulmonary lesion originating from the intracranial meningioma was established.

Findings:

• The study documents an exceedingly rare instance of pulmonary metastasis from a histologically proven benign intracranial meningioma.
• The specific subtype, meningiothelial meningioma, was identified as the source of the solitary lung metastasis.

Implications:

• This case expands the understanding of potential metastatic patterns for intracranial meningiomas.
• It underscores the importance of considering rare metastatic presentations in clinical diagnosis and management.
• Further research may explore the biological mechanisms underlying such rare metastatic events.
