Primary pulmonary meningioma presenting as a micro solid nodule: A rare case report

Area of Science:

• Neurosurgery
• Thoracic Surgery
• Oncology

Background:

• Ectopic meningiomas are rare tumors originating outside the central nervous system.
• Primary pulmonary meningiomas (PPMs) represent a specific subtype of ectopic meningioma located in the lung.
• These tumors are infrequently encountered in clinical practice.

Observation:

• A 65-year-old female presented with a micro solid nodule in the right lower lobe, detected via computed tomography.
• The patient underwent a thoracoscopic lung wedge resection for the nodule.
• Histopathological examination confirmed the presence of a primary pulmonary meningioma.

Findings:

• Primary pulmonary meningiomas manifesting as micro solid nodules are exceptionally rare.
• The case underscores the diagnostic challenge posed by such presentations.
• Histology is crucial for definitive diagnosis of PPM.

Implications:

• Increased clinical and pathological awareness of PPMs is essential for accurate diagnosis.
• Thoracic surgical teams require knowledge of these rare entities for appropriate patient management.
• This case contributes to the understanding of rare lung tumors and their surgical treatment.
