Chest High-resolution Computed Tomography Imaging Features of Lung Involvement in Rheumatoid Arthritis / 中国医学科学院学报

To explore the chest high-resolution computed tomography (HRCT) features in patients with rheumatoid arthritis (RA) complicated with pulmonary involvement. Totally 161 patients with RA with lung involvement were collected from June 2014 to May 2018. The chest HRCT findings were retrospectively analyzed. According to the imaging features as well as the results of history taking,pulmonary function test,pathology,and bronchoalveolar lavage fluid test,RA-related lung diseases (RA-LD) were classified and their clinical characteristics were compared. These 161 RA-LD patients (56 males and 105 females) whose mean age at diagnosis was (60.7±12.8) years (14-85 years) included 87 cases of usual interstitial pneumonia (UIP) (including 16 cases of possible UIP),44 cases of non-specific interstitial pneumonia (NSIP),10 cases of organizing pneumonia,7 cases of lymphocytic interstitial pneumonia,9 cases of small airway disease (SAD) (including 8 cases of bronchiolitis obliterans and 1 case of follicular bronchiolitis),and 4 other lung manifestations (including 3 cases of diffuse alveolar hemorrhage and 1 case of rheumatoid nodules). The UIP group had the oldest average age [(63.3±12.1) years old] and the highest smoking rate (41.4%). The SAD group had the youngest average age [(54.7±15.1) years old] and there was no smoking history. There were significant differences between these two groups (=0.020,<0.001). Seventy patients (43.5%) with RA-LD were complicated with pleural lesions. RA involving the lung is common and has varied imaging manifestations,with interstitial lung diseases (mainly UIP and NSIP) being the most important manifestations. RA patients should undergo lung HRCT as early as possible to identify the lung involvement and related types.

Imaging findings and progress of schistosomal hepatopathy / 中国血吸虫病防治杂志

Schistosomal hepatopathy is widespread in China,and there were more than 30000 schistosomiasis patients with serious liver fibrosis in 2015. This article reviews the pathological manifestations,clinical presentations,imaging findings as well as imaging diagnosis value of schistosomal hepatopathy,and mainly reviews the progress of the typical imaging manifesta-tions of schistosomal hepatopathy and new imaging methods for evaluating the liver fibrosis.

Middle East Respiratory Syndrome-Coronavirus Infection: A Case Report of Serial Computed Tomographic Findings in a Young Male Patient

Radiologic findings of Middle East respiratory syndrome (MERS), a novel coronavirus infection, have been rarely reported. We report a 30-year-old male presented with fever, abdominal pain, and diarrhea, who was diagnosed with MERS. A chest computed tomographic scan revealed rapidly developed multifocal nodular consolidations with ground-glass opacity halo and mixed consolidation, mainly in the dependent and peripheral areas. After treatment, follow-up imaging showed that these abnormalities markedly decreased but fibrotic changes developed.

Cerebral amyloid angiopathy with atypical imagingfindings of subarachnoid hemorrhage / Journal of Rural Medicine

Cerebral amyloid angiopathy (CAA) is observed in most cases of nonhypertensive subcortical hemorrhage involving elderly patients. We herein describe the case of a female in whom a convexal subarachnoid hemorrhage was observed at 55 years of age. The cerebral hemorrhage occurred repeatedly; however, no obvious vascular lesions were observed on a cerebral angiography, and no signs of microbleeding or lesions in the deep white matter were identified on magnetic resonance imaging (MRI). Partial excision of the right frontal cortex and hematoma evacuation were performed, and histopathological examination showed deposition of an acidophilic substance with positive staining for Direct Fast Scarlet (DFS) in the cerebral vascular wall. Finally, brain hemorrhage due to CAA was diagnosed. This case suggests that CAA is an important differential diagnosis in patients with localized non-aneurysmal subarachnoid hemorrhage in the convexity sulcus.
