Clinical and imaging features of 32 cases of coronavirus disease 2019

ObjectiveTo investigate the clinical and imaging features of the corona virus disease 2019(COVID-19).

MethodsThe clinical data and pulmonary high-resolution CT (HRCT) findings of 32 patients with clinically diagnosed COVID-19 were retrospectively analyzed.According to the range and type of lesions, the patients were divided into early stage, progressive stage, termination stage and severe stage, and their HRCT findings were analyzed.

ResultsThere were more male patients than female patients (1.5:1), and most patients had direct or indirect contact history with Wuhan personnel.Fever (84.3%) and cough (59.4%) were the main clinical manifestations, and lower leukocyte count (62.5%), lower lymphocyte count (65.6%) and higher C-reactive protein (71.9%) were common.HRCT findings showed that most lesions were in two lungs (81.3%), which mainly distributed in the middle and outer zone of the two lungs and the subpleural area (96.7%), and most commonly in the left lower lobe (90.6%).Most of the lesions were patchy (84.6%) and irregular (76.9%), the common lesions were ground-glass shadow (80.3%), ground-glass shadow with consolidation (62.5%), complete consolidation (43.8%), thickening of interlobular septum (71.9%), thickening of bronchovascular bundle (68.8%), paving stone sign (43.8%), vacuole/cavity shadow (28.1%) and so on, severe patients could develop "white lung"(3.1%).

ConclusionsThe clinical and imaging features of COVID-19 have certain characteristics and reference value, but it still needs to be considered comprehensively in combination with epidemiology and laboratory indicators.
