Primary Pulmonary Chordoid Meningioma

Area of Science:

• Oncology
• Pathology
• Thoracic Surgery

Background:

• Primary pulmonary meningioma is an exceedingly rare neoplasm.
• Chordoid meningioma is an uncommon variant of meningioma, typically found in the central nervous system (CNS).
• Chordoid meningiomas of the CNS are associated with a high recurrence rate.

Observation:

• A case of primary pulmonary chordoid meningioma presented as a solitary pulmonary nodule (SPN).
• The SPN was surgically resected via thoracoscopic wedge resection.
• Histopathological examination confirmed features consistent with chordoid meningioma.

Findings:

• The diagnosis of primary pulmonary chordoid meningioma was established after excluding a CNS origin through brain imaging.
• The patient remained disease-free for 26 months post-surgery.
• This represents the third reported case of primary pulmonary chordoid meningioma in medical literature.

Implications:

• This case expands the understanding of rare pulmonary neoplasms.
• Highlights the importance of differential diagnosis for solitary pulmonary nodules.
• Suggests that primary pulmonary meningiomas, even rare variants, may have favorable outcomes with complete resection.
