A rarely seen diffuse parenchymal lung disease: Diffuse pulmonary meningotheliomatosis

Pulmoner meningotelyal nodüller (PMN) sıklıkla rezeke edilenakciğer parankim örneklerinin ve otopsilerin patolojik incelenmesisırasında rastlantısal olarak saptan ır. Bu nodüller genellikle asemp-tomatik ve ço ğu zaman tektir. Difüz pulmoner tutulum sıklığı dahaazdır. PMN benign lezyonlar olup, neoplastik ve neolastik olmayanakciğer hastalıkları ve nadiren ekstrapulmoner hastalıklarla ilişkilibulunmu ştur. Multipl bilateral pulmoner nodülleri olan ve video eşliğinde torakoskopik cerrahi (VATS) ile "difüz pulmoner meningotelyomatozis" tan ısı alan bir kadın hasta sunulmu ştur. Difüz pulmoner meningotelyomatozis radyolojik olarak difüz bilateral akciğernodülleri olan hastalarda ayırıc ı tan ı içinde yer almalıdır.

Nadir görülen bir difüz parankimal akciğer hastalığı: Difüz pulmoner meningotelyomatozis

Pulmonary meningothelial-like nodules (MLNs) are usually detected incidentally during pathologic evaluation of resected pulmonaryparenchymal specimens and autopsies. These nodules are generally asymptomatic and most often single. Diffuse pulmonary involve-ment by MLNs is less frequently described. MLNs are benign lesions and have been associated with neoplastic and non-neoplasticpulmonary conditions and occasionally with extrapulmonary diseases. We report a case of a female patient presenting with multipleand bilateral pulmonary nodules diagnosed with "diffuse pulmonary meningotheliomatosis" by video-assisted thoracoscopic surgery(VATS). Diffuse pulmonary meningotheliomatosis should be included in the differential diagnosis of diffuse bilateral lung nodules inthe radiologic studies.
