ABSTRACT

Objective@#To investigate the initial HRCT manifestations and clinical features of imported novel coronavirus pneumonia (NCP) in Guangzhou.@*Methods@#A retrospective analysis of 91 NCP patients admitted to the Guangzhou Eighth People’s Hospital from January 22 to 30, 2020 was performed including 39 males and 52 females, with a median age of 50 (33-62) years, then their clinical features and HRCT characteristics were analyzed.@*Results@#The main clinical presentations included fever in 70 cases and cough in 57 cases(mainly dry coughin39 cases). The first time HRCT showed that 24 cases with NCP were normal, however other 67 cases were abnormal. The ground glass opacity in the lung on HRCT was found in 65 cases, including 64 cases with dilated blood vessel crossing the lesion, 50 cases with thickened adjacent pleura, and 47 cases with thickening of interstitial septum. The patchy opacity was seen in 42 cases, and no enlarged lymph nodes were observed in all patients. As for the lesion distribution, there were two cases with bilateral diffuse changes, 57 cases with multiple lesions, 8 cases with the lesion in only one lobe. The lesions were mainly located under the pleura area in 46 cases, including 39 cases in the lower lobe and other 7 cases in the upper lobe. And there were 13 cases without characteristic distribution in the lung.@*Conclusions@#The initial images of NCP in Guangzhou mainly showed multiple ground glass opacity, which were mostly seen in the subpleural and lower lung fields, most of them with thickened pulmonary interstitium. Guangzhou has a higher proportion of NCP patients with mild and general patients, and some confirmed patients show negative HRCT for the first time. Patients without HRCT changes should be reviewed in a timely manner.

ABSTRACT

Objective:To investigate the initial high resolution CT (HRCT) manifestations and clinical features of imported COVID-19 in Guangzhou.Methods:A retrospective analysis of 91 COVID-19 patients admitted to the Guangzhou Eighth People's Hospital from January 22 to 30, 2020 was performed including 39 males and 52 females, with a median age of 50 (33-62) years,then their clinical features and HRCT characteristics were analyzed.Results:The main clinical presentations included fever in 70 cases and cough in 57 cases(mainly dry cough in 39 cases). The first time HRCT showed that 24 cases with COVID-19 were normal, however other 67 cases were abnormal. The ground glass opacity in the lung on HRCT was found in 65 cases, including 64 cases with dilated blood vessel crossing the lesion, 50 cases with thickened adjacent pleura, and 47 cases with thickening of interstitial septum. The patchy opacity was seen in 42 cases, and no enlarged lymph nodes were observed in all patients.

ABSTRACT

Objective:To investigate the clinical characteristics and CT imaging features of patients with different clinical types of coronavirus disease 2019 (COVID-19), so as to provide a reference for the treatment and evaluation of COVID-19.Methods:The clinical data of 278 patients with COVID-19 admitted to Guangzhou Eighth People's Hospital from January 20th to February 10th in 2020 were collected. The patients were divided into mild, ordinary, severe and critical types. The differences of clinical symptoms and signs, laboratory examination indexes and CT image features of lung in different clinical types were analyzed and compared, and the relationship between clinical and imaging features and clinical types of diseases were analyzed.Results:Among the 278 patients with COVID-19, 130 were male (46.8%) and 148 were female (53.2%), of whom 88.8% (247/278) were 20 to 69 years old. 238 (85.6%) patients combined one or more basic diseases. The source of cases was mainly imported cases ( n = 201, 72.3%), of whom 89 cases were imported from Wuhan, accounting for 44.3% of all imported cases. With the aggravation of the disease, the male composition ratio, age and the number of basic diseases of patients gradually increased, and the incidences of fever, dry cough, chilly or chills, and fatigue in severe and critical patients were significantly higher than those in the mild and ordinary ones. The white blood cell count (WBC), neutrophil counts (NEU) and proportions (NEU%) of the severe and critical patients were higher than those of the mild and ordinary patients [WBC (×10 9/L): 5.7±3.1, 6.5±2.4 vs. 5.4±1.7, 4.9±1.6; NEU (×10 9/L): 4.4±3.1, 4.9±2.5 vs. 2.8±1.2, 2.9±1.3; NEU%: 0.72±0.13, 0.73±0.14 vs. 0.51±0.12, 0.59±0.11; all P < 0.01], while the lymphocyte count (LYM) and ratio (LYM%), platelet count (PLT) were lower than those in the mild and ordinary patients [LYM (×10 9/L): 1.0±0.4, 1.2±0.8 vs. 2.1±0.9, 1.5±0.6; LYM%: 0.21±0.11, 0.20±0.12 vs. 0.40±0.11, 0.32±0.11; PLT (×10 9/L): 177.1±47.8, 157.7±51.6 vs. 215.3±59.7, 191.8±64.3; all P < 0.05]. The level of albumin (Alb) was the lowest in the critical patients and the level of total bilirubin (TBil) was the highest, which was statistically significant as compared with the mild, ordinary and severe patients [Alb (g/L): 33.0±5.8 vs. 42.8±4.4, 39.6±5.1, 34.4±4.2; TBil (μmol/L): 20.1±12.8 vs. 12.0±8.7, 10.9±6.3, 12.2±8.3; both P < 0.01]. Lactate dehydration (LDH) and cardiac troponin I (cTnI) in the severe and critical patients were significantly higher than those in the mild and ordinary patients [LDH (μmol·s -1·L -1): 5.6±2.2, 5.0±2.9 vs. 2.8±0.9, 3.3±1.2; cTnI (μg/L): 0.010 (0.006, 0.012), 0.010 (0.006, 0.012) vs. 0.005 (0.003, 0.006), 0.005 (0.001, 0.008); both P < 0.05]. C-reactive protein (CRP) level of severe patients were higher than that in the mild, ordinary and critical patients [mg/L: 43.3 (33.2, 72.1) vs. 22.1 (16.2, 25.7), 29.7 (19.8, 43.1), 25.8 (23.0, 36.7), P < 0.01]. The level of procalcitonin (PCT) in the severe and critical patients was higher than that in the mild and ordinary patients [μg/L: 0.17 (0.12, 0.26), 0.13 (0.09, 0.24) vs. 0.06 (0.05, 0.08), 0.05 (0.04, 0.09), P < 0.01]. The typical CT imaging features were as follows: the ordinary type mainly showed the single or multiple ground glass shadows on the chest image; the severe type mainly showed the multiple ground glass shadows, infiltration shadows or solid transformation shadows. Compared with the ordinary patients, the lesions increase, and the scope of the lesion expanded to show double lungs. Critical type was mainly manifested as diffuse consolidation of both lungs with multiple patchy density increase shadows, multiple leafy patchy density increase shadows were seen on each leaf, most of them were ground glass-like density, and some were shown separately lung consolidation. Conclusions:Men, advanced aged, and combining multiple underlying diseases are high-risk populations of COVID-19, and they should pay close attention to the risk of progressing to severe or critical type. CT imaging features could be used as an important supplement when diagnosing severe and critical COVID-19.

ABSTRACT

Objective To study the imaging appearances of Rhodococcus equi pneumonia in three patients with acquired immunodeficiency syndrome ( AIDS). Methods Thoracic imaging appearances of Rhodococcus equi pneumonia in three patients with AIDS were retrospectively analyzed. Results The chest radiograph showed patchy consolidations and small nodules ( n = 3 ), large consolidations with multiple cavitations ( n = 2). CT showed large lobar or segmental consolidations with multiple cavitations (n=2),patchy consolidations (n=2), bronchiectasis (n=1), multiple small centrilobular nodules ( n = 2) and tree-in-bud patterns (n = 2). Conclusion The most common radiological findings in AIDS patients with Rhodococcus equi pulmonary infection are large consolidations with multiple cavitations and multiple centrilobular nodules.

ABSTRACT

Objective To study the CT findings of abdominal tuberculosis in patients with AIDS.Methods CT imaging features of abdominal tuberculosis in 33 patients with AIDS were retrospectively analyzed. Results Abdominal lymph adenopathy were observed in 23 cases (69. 7%, 23/33 ).Hepatosplenomegaly were observed in 10 cases (30. 3%, 10/33). Multiple low density nodes in spleen were observed in 14 cases(42. 4%, 14/33)including 9 cases of diffuse, low density nodes (27. 3% ,9/33). Low density lesions in liver were observed in 7 cases (21.2%, 7/33 ) including a case of tuberculous abscess (3.0%, 1/33 ) . Peritoneum and epiploon involvements were found in 5 cases ( 15.2%, 5/33 ) with associated ascites in 2 cases ( 6. 1%, 2/33 ) . Thickening of intestines wall were observed in 4 cases ( 12. 1% ,4/33). Destruction of lumbar vertebra with cold abscess was observed in 1 case (3.0% ,1/33).Abscess in psoas was observed in 1 case (3.0%, 1/33). Conclusion Abdominal tuberculosis in patients with AIDS usually involves multiple organs in the abdomen. CT has an important role in the detection and following up examination of these lesions.
