“…On chest radiographs, sequestration typically appears as a uniform mass within the thoracic cavity or pulmonary parenchyma. Recurrent infection can lead to the development of cystic areas within the mass [14,16]. Air-fluid levels due to bronchial communication have been observed in 26% of ILS cases [17].…”

ÖzetAmaç: Bronkopulmoner sekestrasyonlar nadir görülen konjenital anomalilerdir. Asemptomatik kalabilecekleri gibi intrapulmoner hematom, hemotoraks ve aspergilloma gibi komplikasyonlar gelişebilir, veya karsinoid tümör, adenokarsinoma, skuamoz hücreli karsinoma, sarkom veya pulmoner blastom gibi malign transformasyonlar gösterebilirler. Bronkopulmoner sekestrasyonlar, diğer konjenital anomaliler ile de beraberlik gösterebilirler. Çalışmamızın amacı sekestrasyonlarda tanı konulması sırasında karşılaşılan zorluklar, eşlik eden konjenital anomaliler ve gelişebilecek komplikasyonların vurgulanması-dır. Gereç ve Yöntem: 2003-2015 yılları arasında kliniğimizde opere edilen 19 bronkopulmoner sekestrasyonlu olgunun bilgileri retrospektif olarak değer-lendirilmiştir. Bulgular: Lezyonlar 16 hastada sol tarafta, 3 hastada sağ tarafta yerleşmekteydi ve 15 hastada intralober iken 4 hastada ekstraloberdi. Başvuru sırasında bir hastada ampiyem ve pnömotoraks, bir hastada hemoptizi, iki hastada plevral efüzyon ve iki hastada tekrarlayan pnömoni şikayet-leri mevuttu. İntralober sekestrasyonlu bir olguda eş zamanlı olarak orta kranial fossada 4 cm çaplı araknoid kist tespit edildi. Ekstralober sekestrasyonlu bir olguda postoperatif histopatolojik incelemede multipl tümörlet alanları ve karsinoid tümör bulundu. Postoperatif bir hastada şilotoraks ve bir hastada transuda plevral efüzyon gelişti. Ortalama hastanede kalış süresi 7,9 (3-26) gündü ve mortalite gelişmedi. Tartışma: Pulmoner sekestrasyon tespit edilen hastalarda gelişebilecek komplikasyonlar ve malign transformasyonlar nedeniyle alınacak olan cerrahi kararı geciktirilmemelidir ve eşlik eden konjenital anomaliler açısından dikkatli olunmalıdır. Anahtar KelimelerSekestrasyon; Cerrahi Tedavi; Konjenital Anomaliler; Malign Transformasyon; Karsinoid Tumor Abstract Aim: Bronchopulmonary sequestrations are a rare congenital anomaly. Although they may remain asymptomatic, complications such as intrapulmonary hematoma, hemothorax, and aspergilloma may occur, or they may undergo malignant transformation to become a carcinoid tumor, adenocarcinoma, squamous cell carcinoma, sarcoma, or pulmonary blastoma. Other congenital anomalies may also be associated with bronchopulmonary sequestrations. Our study aimed to emphasize the difficulties in diagnosis, accompanying congenital anomalies, and possible complications. Material and Method: We retrospectively evaluated data obtained from 19 patients with bronchopulmonary sequestration who underwent surgery in our clinic between 2003 and 2015. Results: Lesions were located on the left side in 16 cases and on the right side in three cases, and 15 cases were intralobar, while four were extralobar. One patient had empyema and pneumothorax, one patient had hemoptysis, two patients had pleural effusion, and two had recurrent pneumonia during admission. A patient with intralobar sequestration had a coexistent 4 cm diameter arachnoid cyst in the right middle cranial fossa. Multiple tumorlet areas and carcinoid tumors were postoperatively determine...

“…La TC rappresenta la metodica di scelta nella dimostrazione delle anomalie parenchimali del SPI [32][33][34][35], che si presenta più frequentemente come una massa solida omogenea o non omogenea, con o senza evidenti modificazioni cistiche. In quest'ultimo caso, può evidenziarsi come una massa cistica ben definita o come ampia lesione cavitaria con livello idro-aereo o, più raramente, come un aggregato, talora voluminoso, di piccole lesioni cistiche (voluminosa massa multicistica) con contenuto aereo o fluido [36].…”

In the past few years magnetic resonance angiography (MRA) of the pulmonary vasculature has advanced from a research tool to a clinically relevant imaging modality. Early 2D phase-contrast and time-of-flight (TOF) sequences without the use of contrast agents were time-consuming and limited by considerable imaging and motion artifacts. Since the introduction of MR scanners with stronger gradients (> 20 mT/m) and contrast-enhanced techniques, imaging of the pulmonary vasculature with adequate spatial resolution within a single breathhold is now possible. In the detection of pulmonary embolism in the lobar or segmental arteries, contrast-enhanced MRA is now on the verge of being considered an established modality, possibly competing with conventional pulmonary angiography and contrast-enhanced helical CT. In the future, utilization of phased-array torso coils, the application of navigator pulse sequences, and 3D time-resolved ultrafast MRA will overcome the final limitations of current techniques. Blood-pool MR contrast agents may provide a "one-stop-shopping" approach to the investigation of lower extremity veins and pulmonary arteries in venous thromboembolism.

Imaging Approach to the Diagnosis of Pulmonary Sequestration

Abstract: Plain chest films can provide a diagnostic clue to PS. Sonography, CT and MR are helpful for showing arterial blood supply and for making a definite diagnosis. We recommend a rational imaging approach for the diagnosis of PS.
