The rare congenital anomaly of pulmonary sequestration experience and review of literature
Indian Journal of Thoracic and Cardiovascular Surgery, 2010
Objective Pulmonary sequestration is rare lung anomaly which had very major theories of origin. The aim of this study was to treat this rare congenital anomaly, pulmonary sequestration, which was not diagnosed of preoperatively, in our centre. Methods A retrospective analysis of 10 cases of pulmonary sequestration operated at the centre between 2000 and 2010. A review of the extralobar and intralobar types of sequestration is discussed. All patients were not diagnosed preoperatively. Results Pulmonary sequestration is found more commonly in women (6 patients). In all patients, the diagnosis was made by exploratory thoracotomy. Six patients had intralobar (one was apical) and 4 were extralobar (one apical). Lobectomy for intralobar and sequestrectomy for extralobar sequestration were performed. Conclusions Although rare, some radiological features are sufficiently suggestive of diagnosis of pulmonary sequestration. We believe that pulmonary sequestration should be considered when intrathoracic masses cannot be differentiated through invasive and non-invasive evaluation. In difficult cases methods such as aortagraphy, doppler angiography and Magnetic Resonance (MR) angiography may be used.

The congenital pulmonary airway malformations (CPAM) are extremely rare malformations which are most frequently diagnosed before birth or during childhood and are extremely rarely diagnosed in adults. Sometimes, type II CPAM can be associated with pulmonary sequestrations (PS), especially those extralobar. We present the case of a 39 years old female without any known previous respiratory symptoms until this age, who has having for approximatively 2 months repeated episodes of haemoptysis. The angio-CT exam showed the existence of multiple cyst-like formations in the left inferior pulmonary lobe (LLL) and 2 arteries starting from thoracic aorta that participated at the vascularization of the LLL. We performed a left inferior lobectomy and the postoperative evolution was favorable. The histopathological exam confirmed the diagnosis of type I CPAM associated with intralobar PS. The particularity of the presented case is given by the fact that this patient of 39 years old had no previo...
Pulmonary sequestration: a review of 26 cases
European Journal of Cardio-Thoracic Surgery, 1998
Objectives: Pulmonary sequestration is a continuum of lung anomalies for which no single embryonic hypothesis is yet available. The aim of this study was to assess the diagnostic tools and treatment for the rare condition, pulmonary sequestration, in an unspecialised centre. Methods: We performed an analysis of 26 cases of pulmonary sequestration (paediatric and adult) operated at the Centre Hospitalier Universitaire Vaudois between May 1959 and May 1997. A review of the extralobar and intralobar types of sequestrations is discussed. Angiography is compared to other diagnostic tools in this condition, and treatment is discussed. Results: Twenty-six cases of pulmonary sequestrations, a rare congenital pulmonary malformation, were operated on in the defined time period. Seventy-three percent (19) of the cases were intralobar and 27% (seven) extralobar. Extralobar localisation was basal in 71% and situated between the upper and the lower lobe in 29%. In six cases, the diagnosis was made by exploratory thoracotomy. In the other 20 cases, diagnosis was evoked on chest X-ray and confirmed by angiography. Lobectomy (46%) was the most common treatment procedure. Segmental resection was performed in 30% of the cases and bilobectomy in 4%. Post-operative morbidity was low. The most significant complications were pleural empyema, haemothorax and haemopneumoperitoneum in case of extralobar sequestration. There was no evidence of metaplasia or pre-neoplastic changes. Conclusions: Despite its rarity, some radiological features are sufficiently suggestive of diagnosis of pulmonary sequestration. Investigations are necessary in order to avoid unexpected pathology at the time of operation. Resection of the involved lung leads to excellent results and the long-term outcome is highly favourable.
Pulmonary sequestration: What the radiologist should know
Clinical Imaging, 2021
Pulmonary sequestration consists of a nonfunctioning mass of lung tissue, either sharing the pleural envelope of the normal lung (intralobar) or with its own pleura (extralobar), lacking normal communication with the tracheobronchial tree and receiving its arterial supply by one or more systemic vessels. It is the second most common congenital lung anomaly according to pediatric case series, but its real prevalence is likely to be underestimated, and imaging plays a key role in the diagnosis and treatment management of the condition and its potential complications. We will give a brief overview of the pathophysiology, clinical presentation and imaging findings of intra-and extralobar pulmonary sequestration, with particular reference to multidetector computed tomography as part of a powerful and streamlined diagnostic approach.
A rare case of coexistent intralobar and extralobar pulmonary sequestration
Central European Journal of Medicine, 2012
In the pathology of respiratory tract, sequestration presents as a non-functional lung tissue with no communication with tracheobronchial tree. It represents a rare congenital bronchopulmonary and vascular malformation, which occurs at a frequency of 0.1 to 6%. Intralobar and extralobar sequestrations are extremely rare congenital anomalies, especially if they occur at the same time in a patient. Proper diagnosis and appropriate surgical therapy, in the absence of associated anomalies, provide an excellent prognosis. In this paper, we are describing the simultaneous presence of intralobar sequestration (ILS) in the lower lobe of the left lung and extralobar sequestration (ELS) which is positioned on the aortic arch, in a 53 years old man. Two years post surgery, there is no recurrence or any patomorphological and functional disorders in the respiratory tract.
Computed tomography findings of atypical intralobar pulmonary sequestration: A case series
2021
Introduction: Bronchopulmonary sequestration is a rare congenital abnormality of the lung that has two different types as intralobar and extralobar. In this study, we aimed to present six cases of intralobar sequestration with atypical findings in terms of feeding, drainage, and localization. Methods: Patients diagnosed with intralobar pulmonary sequestration in our clinic between 2015 and 2019 were evaluated retrospectively. Demographical features and atypical computed tomography (CT) findings of the patients were presented by literature. Results: Among 45 patients with intralobar sequestration, 6 (13.3%) (5 males and 1 female) with a mean age of 43.5±25.4(0-78) years old had atypical pulmonary findings on CT images. Atypical features regarding arterial supply was detected in 8.9%, venous drainage in 2.2%, location in 4.4%, radiological appearance in 4.4% and co-existing lesion in 2.2% of the patient with intralobar sequestration. Conclusion: Typical and atypical features of pulmon...

Sequestration spectrum of the lung Pulmonary sequestration Intralobar sequestration Systemic arterial supply to the lung Congenital pulmonary disease a b s t r a c t Intralobar pulmonary sequestration and anomalous systemic arterial supply to the normal lung are two anomalies pertaining to the pulmonary sequestration spectrum. This term brings together a group of related congenital anomalies with a common embryogenesis. Most cases of pulmonary sequestration are unilateral. Bilateral presentation is very rare, with few cases reported. We present two patients with intralobar pulmonary sequestration in the left lung and systemic arterial supply to the otherwise normal right lung. This association is extremely unusual and, to the best of our knowledge, this is the first time it has been diagnosed with multidetector computerized tomography.
