To retrospectively investigate the extravascular thoracic MDCT angiography findings of pulmonary vein stenosis (PVS) in children with a cardiac septal defect. Materials and Methods: Pediatric patients (age ≤ 18 years) with cardiac septal defect and PVS, confirmed by echocardiogram and/or conventional angiography, who underwent thoracic MDCT angiography studies from April 2009 to April 2021 were included. Two pediatric radiologists independently evaluated thoracic MDCT angiography studies for the presence of extravascular thoracic abnormalities in: (1) lung and airway (ground-glass opacity (GGO), consolidation, pulmonary nodule, mass, cyst, septal thickening, fibrosis, and bronchiectasis); (2) pleura (pleural thickening, pleural effusion, and pneumothorax); and (3) mediastinum (mass and lymphadenopathy). Interobserver agreement between the two independent pediatric radiology reviewers was evaluated with kappa statistics. Results: The final study group consisted of 20 thoracic MDCT angiography studies from 20 consecutive individual pediatric patients (13 males (65%) and 7 females (35%); mean age: 7.5 months; SD: 12.7; range: 2 days to 7 months) with cardiac septal defect and PVS. The characteristic extravascular thoracic MDCT angiography findings were GGO (18/20; 90%), septal thickening (9/20; 45%), pleural thickening (16/20; 80%), and ill-defined, mildly heterogeneously enhancing, non-calcified soft tissue mass (9/20; 45%) following the contours of PVS in the mediastinum. There was a high interobserver kappa agreement between two independent reviewers for detecting extravascular abnormalities on thoracic MDCT angiography studies (k = 0.99). Conclusion: PVS in children with a cardiac septal defect has a characteristic extravascular thoracic MDCT angiography finding. In the lungs and pleura, GGO, septal thickening, and pleural thickening are frequently seen in children with cardiac septal defect and PVS. In the mediastinum, a mildly heterogeneously enhancing, non-calcified soft tissue mass in the distribution of PVS in the mediastinum is seen in close to half of the pediatric patients with cardiac septal defect and PVS.

Anomalous Pulmonary Venous Connection

Purpose: To evaluate extravascular findings on thoracic MDCT angiography in secondary pulmonary vein stenosis (PVS) due to total anomalous pulmonary venous connection (TAPVC) repair in children. Materials and Methods: All patients aged ≤18 years with a known diagnosis of secondary PVS after TAPVC repair, confirmed by echocardiography, conventional angiography, and/or surgery, who underwent thoracic MDCT angiography studies between July 2008 and April 2021 were included. Two pediatric radiologists independently examined MDCT angiography studies for the presence of extravascular thoracic abnormalities in the lung, pleura, and mediastinum. The location and distribution of each abnormality (in relation to the location of PVS) were also evaluated. Interobserver agreement between the two independent pediatric radiology reviewers was studied using kappa statistics. Results: The study group consisted of 20 consecutive pediatric patients (17 males, 3 females) with secondary PVS due to TAPVC repair. Age ranged from 2 months to 8 years (mean, 16.1 months). In children with secondary PVS due to TAPVC repair, the characteristic extravascular thoracic MDCT angiography findings were ground-glass opacity (19/20; 95%), septal thickening (7/20; 35%), pleural thickening (17/20; 85%), and a poorly defined, mildly heterogeneously enhancing, non-calcified soft tissue mass (17/20; 85%) which followed the contours of affected pulmonary veins outside the lung. There was excellent interobserver kappa agreement between two independent reviewers for detecting extravascular abnormalities on thoracic MDCT angiography studies (k = 0.99). Conclusion: Our study characterizes the extravascular thoracic MDCT angiography findings in secondary pediatric PVS due to TAPVC repair. In the lungs and pleura, ground-glass opacity, interlobular septal thickening, and pleural thickening are common findings. Importantly, the presence of a mildly heterogeneously enhancing, non-calcified mediastinal soft tissue mass in the distribution of the PVS is a novel characteristic thoracic MDCT angiography finding seen in pediatric secondary PVS due to TAPVC repair.

Abstract Case description We report the case of a 78 year old man who was referred to our hospital following identification of an intracardiac mass on transthoracic echocardiogram (TTE). The study was for work-up of a recent left middle cerebral artery thromboembolic stroke, with successful endovascular clot retrieval. His only other active medical issue was metastatic prostate cancer with bony involvement, on palliative hormone therapy with a well controlled prostate specific antigen level. He was an ex-smoker and and had an ECOG performance status of zero. On physical examination, the patient was clinically well, with unremarkable cardiopulmonary auscultation. The TTE demonstrated an echodense mass in the left atrium (LA), with Doppler colour giving a suggestion of its size (image A). The subsequent transoesophageal echocardiogram illustrated a large, well defined, heterogenous, echodense mass dominating the LA (image B). It was not adherent to the interatrial septum. There was no significant spontaneous echocontrast or thrombus formation in the left atrial appendage (LAA). Considering the location of the mass, the presumptive diagnosis of atrial myxoma was less likely. Differential diagnoses we considered included pure thrombus, infection and benign or malignant cardiac tumours. It was unlikely that this patient had a pure thrombus only considering the LAA was clear. He also did not have any non-specific or focal clinical features suggestive of infection. The patient went on to have a gated CT thoracic aortogram, which showed a contrast-enhancing soft tissue mass within the LA measuring approximately 50x40 millimetre, which invaded into the left inferior pulmonary vein, and was contiguous with a soft tissue mass in the left lower lobe of the lung (image C). He also had a positon emission tomography scan, which showed the highly metabolically active mass in the lung invading into the left inferior pulmonary vein, and as well as left atrium (image D). The patient underwent a biopsy of this left lower lung lesion, which confirmed squamous cell carcinoma of lung origin. Due to the large tumour burden in the LA, the joint decision with medical and radiation oncology teams, was not to administer systemic chemo- or localised radiotherapy, as this would lead to high risk of tumour embolisation. The patient also had a short period of therapeutic anticoagulation with intravenous unfractionated heparin to treat the likely thrombotic coating to the left atrial tumour extension, but developed a retroperitoneal haematoma, and hence anticoagulation was ceased. The patient was referred to palliative care services, and returned back to the community. Conclusion Cardiac tumours, whether primary or secondary, are rare. They are most frequently identified on post-mortem examination. This case is unusual, in that the patient had a second primary tumour and has remained completely asymptomatic prior to embolic presentation, despite the large size of the mass.

Measurements of crown-heel length, head circumference, and birth weight were made on a large number of newborn infants. Birth weight by itself was frequently not a valid measure of fetal growth impairment. By including measurements of body length and head size along with birth weight, four distinct patterns of fetal growth impairment were identified. The four patterns included infants who had abnormally short body lengths for dates, infants who had evidence of disproportionate growth between body length and head circumference, infants who accumulated excessive amounts of soft-tissue mass, and infants who accumulated too little soft-tissue mass. Criteria for diagnosing each pattern were obtained prospectively and have been presented with allowances made for the effects of race, sex, fetal age, and parity on each pattern. The separate identification of the four patterns provided a more precise description of fetal growth impairment than could be obtained from birth weight and calculated gestational age.
