Diffuse pulmonary meningotheliomatosis: A case report

Abstract

A 57-year-old female presented with chest discomfort and exertional dyspnea but no other respiratory symptoms or history of malignancy. Chest CT revealed multifocal centrilobular nodules with ground-glass opacity in both lungs. Thoracoscopic wedge resection was done, and histological examination confirmed interstitial meningothelial-like nodules, consistent with diffuse meningotheliomatosis. The patient was discharged without complications and showed no disease progression on follow-up CT at 3 months, maintaining stability during 6 months of outpatient observation. Diffuse pulmonary meningotheliomatosis is an exceedingly rare condition, but this may be one of the causative etiologies in patients with diffuse bilateral pulmonary nodules.
