Abstract

Aim: In this study, it is aimed to define high resolution computed tomography (HRCT) findings that can be used to distinguish collagen tissue disease associate dinterstitial lung disease (CTD-ILD) from interstitial pulmonary fibrosis (IPF). Material and Methods: The hospital database was scanned retrospectively and CTD-ILD and IPF cases diagnosed between 2016-2020 with HRCT examinations were included. Usual interstitial pneumonia (UIP), probable UIP and nonspecific interstitial pneumonia (NSIP) patterns, reticulation, honeycombing, large honeycomb cysts, traction bronchiectasis, ground-glass, straight edge sign and anterior upper lobe sign were compared between CDH-ILD and IPF groups and rheumatoid arthritis, scleroderma and Sjögren'ssyndrome sub groups. Results: There were 100 patients (50 IPF and 50 CTD-ILD). Among CTD group 30% (n=15) was RA, 8% (n=29) was scleroderma and 12% (n=6) was Sjogren’s syndrome. Reticulation, honeycombing and traction bronchiectasis (UIP) were significantly higher in the IPF group, and ground-glass (NSIP) was significantly higher in the CDH group. There was no significant difference between IPF and CDH-ILD groups in terms of anterior upper lobe and straight edge signs. Straight edge sign was significantly higher in Sjogren than other subgroups of CTD. The scleroderma group consisted of younger and mostly female cases compared to IPF. Ground-glass and NSIP patterns were found more commonly in scleroderma than IPF, while reticulation, honeycombing, large honeycomb cysts and traction bronchiectasis were found less. Conclusion: HRCT plays an important role in the diagnosis and differential diagnosis of IPF and CTD-ILD. Straight edge sign can distinguish Sjogren's sydrome ILD from lung involvements of RA and scleroderma. Anterior upper lobe sign may accompany the UIP pattern in IPF and CTD-ILD.

Özet

Amaç: Bu çalışmada kollajen doku hastalığı ile ilişkili interstisyel akciğer hastalığı (KDHİAH)’nı interstisyel pulmoner fibrozis (İPF)’den ayırt etmede kullanılabilecek yüksek çözünürlüklü bilgisayarlı tomografi (YÇBT) bulgularının tanımlanması amaçlanmaktadır. Gereç ve Yöntem: Hastane veri tabanı retrospektif olarak taranarak 2016-2020 yılları arasında tanı alan ve YÇBT incelemeleri bulunan KDH-İAH ve İPF olguları çalışmaya dahil edildi. YÇBT’de olağan interstisyel pnömoni (OİP), olası OİP ve nonspesifik interstisyel pnömoni (NSİP) paternleri, retikülasyon, balpeteği, büyük balpeteği kist, traksiyon bronşektazisi, buzlucam, düz kenar bulgusu ve anterior üst lob bulgusu KDH-İAH ve İPF grupları ve KDH’nın romatoid artrit (RA), skleroderma ve Sjögren sendromu subgrupları arasında karşılaştırıldı. Bulgular: Çalışmaya 50’si İPF, 50’si KDH olmak üzere 100 hasta dahil edildi. KDH grubunun %30’u (n=15) RA, %8’i skleroderma (n=29) ve %12’si (n=6) Sjögren sendromu tanılıydı. İPF grubunda retikülasyon, balpeteği ve traksiyon bronşektazisi (OİP paterni), KDH grubunda ise buzlucam (NSİP paterni) anlamlı olarak daha fazlaydı. Anterior üst lob bulgusu ve düz kenar bulgusu açısından İPF ve KDH-İAH grupları arasında anlamlı fark yoktu. Ancak düz kenar bulgusu Sjögren’de KDH’nın diğer subgruplarına göre anlamlı olarak daha fazlaydı. Skleroderma grubu İPF’e göre daha genç ve kadın ağırlıklı olgulardan oluşmaktaydı. Sklerodermada buzlucam ve NSİP paterni İPF’ye göre daha fazla, retikülasyon, balpeteği, büyük balpeteği kistler ve traksiyon bronşektazisi daha az oranlarda saptandı. Sonuç: YÇBT, İPF ve KDH-İAH tanısı ve ayırıcı tanısında önemli bir rol oynamaktadır. Düz kenar bulgusu Sjögren’e bağlı İAH’nı, RA ve sklerodermanın akciğer tutulumundan ayırt ettirebilir. Anterior üst lob bulgusu İPF’de ve KDH-İAH’da OİP paternine eşlik edebilmektedir.
