Pulmonary sequestration with Aspergillus infection presenting as massive hemoptysis and hemothorax with highly elevated carcinoembryonic antigen in pleural effusion that mimics advanced lung malignancy.

Eur J Med Res 2021 May 25;26(1):48. Epub 2021 May 25.

Department of Respiratory and Critical Care Medicine, West China Hospital of Sichuan University, Chengdu, 610046, Sichuan, China.

Background: Pulmonary sequestration (PS) associated with massive hemoptysis, hemothorax, and elevated tumor markers or even lung malignancy has been reported in several studies. These clinical features combined with lung lesions on chest imaging are sometimes hard to differentiate from lung malignancies and often complicate the diagnostic procedure.

Case Presentation: A 45-year-old man with PS presented with massive hemoptysis, hemothorax, and extremely elevated carcinoembryonic antigen (CEA) in pleural effusion was initially misdiagnosed with advanced lung carcinoma, but was ultimately diagnosed with PS with Aspergillus infection. Read More

Revising the classification of lung sequestrations.

Clin Imaging 2021 Feb 23;77:92-97. Epub 2021 Feb 23.

Unit of Pediatric Radiology, Department of Radiology, University Hospital of Lausanne (CHUV) and University of Lausanne (UNIL), Rue du Bugnon 46, 1011 Lausanne, Switzerland. Electronic address:

Purposes: The classification of lung sequestrations distinguishes between extralobar and intralobar types, according to their venous drainage - systemic vs pulmonary - and the presence or absence of independent pleura. However, imaging, surgical and/or pathological findings often differ from this description. The objectives of this article are to quantify the percentage of lung sequestrations that do not fit the classic description of extra- and intralobar types and to evaluate the accuracy of the currently used classification.

Pulmonary sequestration: What the radiologist should know.

Clin Imaging 2021 May 3;73:61-72. Epub 2020 Dec 3.

Diagnostic and Interventional Radiology, Department of Translational Research, University of Pisa, Via Roma, 67, 56126 Pisa, Italy.

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.

Fetal abdominal tumors are rare, usually benign, and cause a great deal of anxiety for expectant parents and the physicians counseling them. In this paper the author reviews the most common fetal abdominal tumors in the liver (hemangioma, mesenchymal hamartoma, hepatoblastoma, metastases) and the kidney (congenital mesoblastic nephroma, Wilms tumor, malignant rhabdoid tumor, and clear cell sarcoma), and suprarenal mass lesions (adrenal neuroblastoma, adrenal hemorrhage, and subdiaphragmatic extralobar pulmonary sequestration). The author describes the imaging approach, imaging appearance and differentiating features of tumors, and differences between fetal and childhood appearances of tumors. Read More

Fetal ultrasound and magnetic resonance imaging: a primer on how to interpret prenatal lung lesions.

Pediatr Radiol 2020 12 30;50(13):1839-1854. Epub 2020 Nov 30.

Department of Radiology, National Maternity Hospital, Dublin, Ireland.

Fetal lung lesions include common lesions such as congenital pulmonary airway malformation (CPAM), bronchopulmonary sequestration (BPS) and combined CPAM-BPS hybrid lesions, as well as less common entities including congenital lobar emphysema/obstruction, bronchial atresia, bronchogenic cysts and rare malignant pulmonary lesions such as pleuropulmonary blastoma. Fetal lung lesions occur in approximately 1 in 15,000 live births and are thought to arise from a spectrum of abnormalities related to airway obstruction and malformation, with the lesion type depending on the timing of insult, level of bronchial tree involvement, and severity of obstruction. Lesions vary from small and asymptomatic to large and symptomatic with significant mass effect on surrounding structures. Read More

A Modified VATS Procedure for Treating Adult Intralobar Pulmonary Sequestration.

Thorac Cardiovasc Surg 2021 03 17;69(2):194-196. Epub 2020 Nov 17.

Department of Thoracic Surgery, Sun Yat-sen University First Affiliated Hospital, Guangzhou, China.

Video-assisted thoracoscopic surgery (VATS) makes it possible to treat intralobar sequestration (ILS) more minimally invasive compared with conventional open surgery. However, this procedure is challenging to expose and isolate the aberrant arteries of ILS and the risk of bleeding is high. Herein, we developed a modified VATS procedure in which the aberrant vessels are treated in the last step of lobectomy, rather than at the beginning. Read More

Three-dimensional computed tomography and indocyanine green-guided technique for pulmonary sequestration surgery.

Gen Thorac Cardiovasc Surg 2021 Mar 19;69(3):621-624. Epub 2020 Oct 19.

Division of General Thoracic Surgery, Department of Surgery, Shinshu University School of Medicine, 3-1-1 Asahi Matsumoto, Nagano, 390-8621, Japan.

Patients with pulmonary sequestration are at risk of life-threatening bleeding during lung resection. To perform safe and adequate lung resection in patients with pulmonary sequestration, we utilized the following combination of techniques: (1) three-dimensional computed tomographic (3D-CT) imaging for preoperative planning and intraoperative identification of blood vessels, including aberrant arteries, and (2) intraoperative intravenous administration of indocyanine green (ICG). We describe our surgical technique through three cases who underwent lung resection for pulmonary sequestration using 3D-CT and fluorescence navigation with ICG. Read More

A Scimitar Syndrome Variant Associated with Critical Aortic Coarctation in a Newborn.

Am J Case Rep 2020 Oct 8;21:e923162. Epub 2020 Oct 8.

Mother and Child Health Institute of Serbia, School of Medicine, University of Belgrade, Belgrade, Serbia.

BACKGROUND Scimitar syndrome (SCS) is a rare congenital cardiopulmonary malformation, characterized by anomalous pulmonary venous drainage from the right lung associated with aortopulmonary collateral arteries and pulmonary hypoplasia. The variant described in the case presented here, with total anomalous right pulmonary venous drainage into the superior and inferior vena cava, can be expected in 2% of patients with scimitar syndrome. To the best of our knowledge, the association between the variant of SCS and coarctation of aorta described in our patient has never been reported before in the literature. Read More

Medicine (Baltimore) 2020 Oct;99(40):e22574

Department of Surgery, Xuzhou Central Hospital, Xuzhou, China.

Rationale: Pulmonary sequestration (PS) presenting with elevated serum tumor markers is rare, and it might be misdiagnosed as malignancy.

Patient Concerns: A 26-year-old asymptomatic male patient was admitted because the x-ray showed an intrathoracic lesion. Meanwhile, the serum neuron-specific enolase (NSE) was elevated. Read More

Combined endovascular and surgical approaches to treat intralobar pulmonary sequestration: a case report.

Ann R Coll Surg Engl 2021 Jan 24;103(1):e35-e37. Epub 2020 Sep 24.

Newcastle upon Tyne Hospitals, Newcastle upon Tyne, UK.

Pulmonary sequestration is a congenital abnormality of a non-functional pulmonary mass with anomalous systemic arterial supply. Surgical resection is the gold standard treatment, but it carries a risk of life-threatening haemorrhage from accidental injury of the anomalous artery. Endovascular embolisation has been introduced as a safe alternative, but does not eliminate the possibility of symptom recurrence. Read More

Department of Pediatric Surgery, Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico di Milano, Milano, Lombardia, Italy.

Pulmonary sequestration (PS) is mostly asymptomatic but there is a proportion of fetuses that develop hydrops, leading to fetal or neonatal death. Fetal treatments are available, but postnatal management of the residual lesions is not uniformly defined. We present two cases of combined pre- and postnatal minimally invasive approach to complicated extra-lobar PS. Read More
