Abstract
INTRODUCTION: Primary pulmonary meningioma (PPM) is an exceptionally rare form of ectopic meningioma, with few cases documented in the literature, and even fewer reports of recurrence following surgical resection. CASE PRESENTATION: This case study details a 69-year-old male patient diagnosed with PPM postoperatively, who experienced a recurrence 10 years after the initial surgery, necessitating a second surgical intervention. The postoperative pathological diagnoses from both surgeries confirmed transitional type primary pulmonary meningioma. The Ki-67 index from the first surgery was less than 1%, while the second postoperative pathology demonstrated a Ki-67 index of 5%. CONCLUSION: The case emphasizes that, despite its benign classification, PPM has a potential for recurrence, underscoring the importance of ongoing, long-term follow-up in post-surgical management.
