# Recurrence of Primary Pulmonary Meningioma 10 Years after Surgery: A Case Report

## TL;DR

A rare case of lung meningioma recurring 10 years after surgery highlights the need for long-term monitoring.

## Contribution

This case report documents a rare recurrence of primary pulmonary meningioma after a decade, emphasizing the need for long-term follow-up.

## Key findings

- A 69-year-old male had a recurrence of primary pulmonary meningioma 10 years after initial surgery.
- The Ki-67 index increased from less than 1% to 5% between the first and second surgeries.
- The case highlights the potential for recurrence in benign primary pulmonary meningioma.

## Abstract

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.

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%.

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.
