Diffuse Pulmonary Meningotheliomatosis Mimicking Multiple Lung Metastases of Prostate Cancer: A Case Report

Year: 2025

Type: article

Abstract: Diffuse pulmonary meningotheliomatosis (DPM) is a benign pulmonary disease characterised by widespread bilateral minute pulmonary meningothelial-like nodules that often appear as multiple ground-glass nodules on chest imaging. We present the case of a 64-year-old man with prostate cancer who was found to have multiple pulmonary nodules during cancer staging and was initially suspected to have lung metastases. A surgical lung biopsy confirmed the diagnosis of DPM, allowing the patient to receive curative treatment for localised prostate cancer. DPM is a rare condition reported to be possibly associated with malignancy; however, little is known about its pathogenesis. This case demonstrates the importance of considering DPM in the differential diagnosis of multiple pulmonary nodules, including lung metastases, and the need for further research.
