Imaging findings of spontaneous thymic hemorrhage in infancy: Case report and literature review

The authors report imaging findings of spontaneous thymic hemorrhage, which is a rare entity in infancy, in a 4-month-old boy with congenital factor VII deficiency presented with acute respiratory distress and anemia. Widening of superior mediastinum and left pleural effusion were detected on the chest radiograph. Ultrasound and computed tomography of the chest revealed diffusely enlarged thymus with heterogeneous parenchyma from poorly-defined areas of altered echogenicity or attenuation. Vascular flow was depicted within the abnormal thymus in color-mode sonography. The spontaneous involution of thymic abnormality seen on serial ultrasonography confirmed the diagnosis of thymic hemorrhage, resulting in avoidance of further unnecessary imaging or invasive procedure.

Renal lymphangiectasia is a rare benign condition of the kidney without specific clinical presentations. Classic imaging findings are described in literature. Here, we present a case of renal lymphangiectasia with history of bilateral flank pain and abnormal renal function tests. The radiological appearance on ultrasound (US) and computed tomography (CT) showed features of bilateral renal lymphangiectasia but the patient refused invasive procedure for aspiration of the cysts. So, follow-up of the patient was done by magnetic resonance imaging (MRI). Imaging findings of our case on US, CT, and MRI are discussed along with details of the additional finding of dilated retroperitoneal lymphatic channels, cisterna chyli, as well as the thoracic duct.

Congenital Factor

SummaryThe inheritance of congenital factor VII deficiency was investigated in 2 unrelated families. Out of 68 individuals, 4 (3 proven and 1 highly probable) were found to have severe factor VII deficiency (<C 0.1% factor VII), and 29 appeared to be heterozygotes (30—60% factor VII). The coagulation defect is due to an autosomal gene of intermediate expression and complete penetrance. The recessive character of the haemorrhagic diathesis due to the homozygous state for the abnormal gene is clearly demonstrated.

Coronary sinus aneurysm (CSA) is an extremely rare entity. Herein, we present an unusual case of an 18-year-old symptomatic female patient with a giant CSA. Secondary vena cava aneurysms were also manifested. The final diagnosis was confirmed by enhanced computed tomography (CT) and cardiac catheterization. As far as we know, it is the first case that such a giant CSA coexists with secondary vena cava aneurysms. Considering the complexity of postoperative reconstruction, we believe that heart transplantation may be the optimal way for treatment. The patient received anticoagulant due to the superior vena cava (SVC) thrombosis while waiting for a donor.

Radiologic Characteristics

Background: Coronaviruses are non-segmented enveloped positive-sense single-strand RNA viruses, and COVID-19 is the seventh known coronavirus, infecting humans. Objective: As the COVID-19 continued to spread the world wildly, every radiologist or clinician needs to be familiar with its imaging findings. Methods: In this study, we reviewed available studies to provide a comprehensive statement on COVID-19 imaging findings. Results: Ground-glass opacities, linear opacities, interlobular septal thickening, consolidation, and Crazy-paving patterns are the most frequent findings in computed tomography (CT) of lungs in patients with COVID-19 pneumonia, which are mostly bilateral, multifocal, and peripheral. Staff needs to follow some rules to reduce infection transmission. Conclusion: COVID-19 pneumonia is a new global concern which has many unknown features. In this article, the radiologic characteristics of COVID-19 pneumonia are discussed. We also discussed appropriate protective measures that the radiology team should be aware of.

The Individual

AbstractOur understanding of the manifestations of pneumoconioses is evolving in recent years. Associations between novel exposures and diffuse interstitial lung disease have been newly recognized. In advanced asbestosis, two types of fibrosis are seen, probably related to dose of exposure, existence of pleural fibrosis, and the host factor status of the individual. In pneumoconiosis of predominant reticular type, nodular opacities are often seen in the early phase. The nodular pattern is centrilobular, although some in metal lung show perilymphatic distribution, mimicking sarcoidosis. High-resolution computed tomography enables a more comprehensive correlation between the pathologic findings and clinically relevant imaging findings. The clinician must understand the spectrum of characteristic imaging features related to both known dust exposures and to historically recent new dust exposures.
