The case of a 43-year-old woman with intralobar pulmonary sequestration, Pryce type one, is presented. The medical history was characterised by recurrent bronchopneumonia, productive cough with purulent sputum and hemoptysis in the last three years. Diagnosis was made by CT angiography: multiplanar, maximum intensity projection and volume rendering reconstructions were visualised. A volume reduction of middle and lower lobe with multiple cyst-like bronchiectasis was detected and no evident relationship with tracheobronchial tree was pointed out. Reconstructions aimed at evaluating bronchial structures demonstrated no patency of middle and lower lobar bronchi. The study carried out after contrast medium infusion in arterial phase showed a vascular disorder characterised by an accessory arterial branch arising from the upper portion of thoracic aorta which, after moving caudally to pulmonary hilus with a tortuous course, supplied the atelectatic parenchyma. No anomalous venous drainage was detected. The patient underwent surgery with resection of two pulmonary lobes. CT compares favourably with other alternative imaging technique for pulmonary sequestration as multiplanar reconstructions allow not only the detection of supplying vessel, but also the accurate description of heterogeneous characteristics of the mass and adjacent structures. Finally an imaging-based diagnostic algorhythm is proposed.

Lower Airways

Bronchopulmonary sequestration is a rare congenital pulmonary abnormality of the lower airways, which includes an abnormal and non-functioning lung tissue not communicating with the tracheobronchial tree and having aberrant blood supply from systemic circulation with variable venous drainage. The incidence of sequestration is around 0.15%–6.4% of all congenital lung malformations.Common presenting features are cough and expectoration. Misdiagnosed cases may present with recurrent infections and haemoptysis. CT of the chest with contrast is the imaging modality of choice.This is a case report of a 32-year-old woman who presented with cough and haemoptysis. CT of the chest showed a multiloculated mass-like lesion in the left lower lobe with a feeding artery from coeliac plexus and venous drainage via the normal left pulmonary vein.Based on CT chest findings, diagnosis of intralobar pulmonary sequestration was made. The patient was reviewed by cardiothoracic surgeons and underwent surgical resection of the sequestrated lung.Common presenting features are cough and expectoration. Misdiagnosed cases may present with recurrent infections and haemoptysis. CT of the chest with contrast is the imaging modality of choice.

Intracranial Circulation

The introduction of the new helical CT technique, particularly its innovation in multislice CT, allows an accurate study of the intracranial vascular “architecture”. The technological progress in 3D imaging, such as maximum intensity projection (MIP) and volume-rendering (VR) technique, appears to be very helpful in detecting intracranial aneurysms, particularly around the circle of Willis. New reconstruction software optimises the evaluation of aneurysm size and the precise visualisation of the neck and its relationship with adjacent structures (vessels, bone …). These non invasive imaging modalities also can improve the correct planning of the following treatments.

AbstractIn 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.

Background: The development in the field of image reconstruction is growing rapidly along with the development of  CT Scan. In  the early stages of  MSCT abdominal artery is usually found  various kinds of vascular abnormalities such as stenosis, aneurism and others. Post processing image techniques commonly used include MPR and MIP. The purpose of this study is to determine whether there is a difference between MPR and MIP techniques and to know which one is better between the two.Methods: This  research was  quantitative study with experimental approach. The study was conducted at Bhakti Dharma Husada Surabaya Hospital  with 15 samples by performing reconstruction on vascular anatomical image of coronal examination of  abdominal MSCT. Assessment of anatomical information data is done by 2 respondents. Data analysis was done by kappa test followed by Wilcoxon sign rank test.Result : The results showed the difference between the post-processing of MIP and MPR on the coronal stages of the early arterial phase of the abdominal MSCT examination, based on the results of  non-parametric statistical test analysis (Wilcoxon) showed  a significant value of p value = 0.001. The result of MIP mean rank value (8,46) is higher than the mean rank value of MPR (1,50), it can be known that post proceeding MIP technique on coronal phase cuts early arterial examination of abdominal MSCT produces better anatomical image information.Conclusion: On examination of abdominal MSCT in the early arterial phase should be at the time of processing the image is also done by using post-processing MIP because more clearly than the MPR.

Foregut Malformation

We describe a previously unreported bronchopulmonary foregut malformation wherein a segment of a bronchus of the lower lobe of the left lung in a 4-year-old girl was entirely esophageal in structure. No communication was identified between the tracheobronchial tree and the esophagus by radiologic examination or at surgery. The esophagus-like bronchus was associated with an adjacent atretic bronchus and a downstream cavity in the lower lobe of the left lung. The child sought clinical attention because of recurrent pulmonary infections localized to the lower lobe of the lung. We posit that this esophagus-like bronchus is a novel noncommunicating bronchopulmonary foregut malformation.

Pulmonary sequestrations are congenital masses of aberrant, nonfunctioning pulmonary tissue that usually do not connect with the bronchial tree and derive their arterial blood supply from systemic vessels, most often the distal thoracic or upper abdominal aorta. The majority of sequestrations are intralobar and contained within the visceral pleura of the normal lung; these usually have their venous drainage to the pulmonary venous system. Extralobar sequestrations have a separate pleural covering and usually drain to systemic veins or the portal venous system.1-3 Patients most often come to clinical attention with repeated respiratory infections.2 The sequestered segment is usually visualized radiographically as a nonaerated opacity at the medial lung base, more often left-sided.

Introduction: The importance of the lymphatic circulation in Fontan physiology is incompletely understood and may have implications in Fontan ‘failure’. Non-invasive imaging of the lymphatic system with heavily T2-weighted MRI sequences could be a useful tool for patient surveillance and prognostication. We sought to quantify lymphatic burden in Fontan patients and correlate with clinical status. Methods: Consecutive pediatric Fontan patients, <18 years-old with clinical cardiac MRI that had routine acquisition of lymphatic 3D T2 FSE imaging performed from May 2017 to Oct 2019 were included. ‘Lymphatic burden’ was quantified by thresholding-based segmentation of the 3D T2 FSE maximum intensity projection image (fig), generating a surrogate measurement of lymphatic volume, and was performed by 2 independent readers blinded to patient status. Spearman correlation and Mann-Whitney tests were used. Results: There were 48 patients (27 males) with median age at MRI of 12.9 (9.4-14.7) years, age at Fontan of 3.3 (2.9-3.8) years, and time from Fontan at MRI of 9.2 (5.9-10.4) years. Inter-rater agreement for lymphatic burden was excellent (ICC 0.96 [0.94-0.98]). Greater lymphatic burden correlated with hospital length of stay and duration of chest tube drainage post-Fontan (r =0.423, p=0.003 and r=0.419, p=0.003). Median lymphatic burden was greater in patients that had chylous effusions post-Fontan (286 (157-492) ml vs 123 (60-271) ml, p=0.011) and in patients with composite adverse outcome (n=12) defined by heart failure (n=3), transplant assessment (n=2), recurrent effusions (n=8), Fontan thrombus (n=2), and/or PLE (n=6) post-Fontan; (458 (266-2016) ml vs 130 (272-256) ml, p=0.005). Pre-Fontan mean PA pressure and time from Fontan did not correlate with lymphatic burden (r=0.062, p=0.676 and r=0.139, p= 0.343). Conclusion: Quantification of MR lymphatic burden is a reliable tool to assess lymphatic status post-Fontan and is associated with clinical outcomes.
