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 evaluate the etiology and CT features of thoracic lymphadenopathy in patients with acquired immunodeficiency syndrome (AIDS).Methods CT features of thoracic lymphadenopathy in 178 AIDS patients were retrospectively analyzed.Results Of 668 AIDS patients with thoracic lymphadenopathy,174 were proved to be infections including Penicilliosis marneffei (n =117),tuberculosis (n =42),cryptococcosis (n =10) and non-tuberculous mycobacteria (n =5).Four were proved to be tumors including 3 Kaposi's sarcomas and 1 lymphoma.The enlarged mediastinal and hilar lymph node presented as homogeneous soft-tissue density in 140 patients,with central low attenuation in 29 patients,as extreme low attenuation in 9 patients on plain CT scan and showed homogeneous enhancement in 28 patients,rim enhancement in 19 patients,non enhancement in 2 patients on enhanced CT scan.Accompanied CT findings included diffuse pulmonary micro-nodules (n =45),primary complex or similar primary complex (n =13),pleural effusion (n =59),pericardial effusion (n =24),sandwich sign in the small bowel mesentery (n =31).The CT findings of penicilliosis marneffei and tuberculosis were compared with chisquare test.There were significant differences on homogeneous soft-tissue density,central low attenuation,homogeneous enhancement,rim enhancement,diffuse pulmonary micro-nodules,primary complex or similar primary complex,sandwich sign,pleural effusion (x2 =32.62,43.82,12.13,15.72,11.76,11.06,5.44,4.07,P < 0.05).Conclusions Thoracic lymphadenopathy can be caused by infections and tumors in AIDS.CT plays an important role for the differential diagnosis.

ABSTRACT

ObjectiveTo summarize X-ray and CT findings of soft tissue and bone infections secondary to acquired immunodeficiency syndrome (AIDS).MethodsThe data of X-ray and CT findings of soft tissue and bone infections in 18 patients with AIDS were retrospectively collected and analyzed.ResultsOf 18 patients with AIDS,the CT features of soft tissue demonstrated that subcutaneous patchy high density in 1 case which considered as cellulitis,round low density lesions with ring enhancement in 6 cases which considered as soft tissue abscesses,heterogeneous density lesions with peripheral enhancement in 1 case which considered as pyomyositis.Of 18 patients with AIDS,septic arthritis was found in 4 cases involving knee lesion in 3 cases and hip lesion.In the 4 case,the X-ray films showed bony destruction in 2 cases and the CT showed bone destruction in 3 cases and arthroedema in 4 cases.Of 18 patients with AIDS,osteomyelitis was found in 9 cases of which tuberculosis was considered in 8 cases and vertebral involvement in 6 cases.In the 9 cases,the X-ray films and CT displayed bony destruction,hyperostosis,small sequestra,and intervertebral space narrowing.Of 18 patients with AIDS,costal lesions were found in 3 cases in which the CT showed expandable bony destruction.Of 18 patients with AIDS,ilium and cacroihac joint lesions were found in 1 case in which the X-ray films and CT showed bony destruction,sequestra,and joint widening.Of 18 patients with AIDS,chronic pyogenic osteomyelitis of femur was found in 1 case in which the X-ray films showed bony destruction,hyperostosis osteosclerosis,and periosteal reaction.Conclusion The X-ray and CT features of soft tissue and bone infections secondary to AIDS are characterized.The X-ray and CT are useful tools to early diagnose soft tissue and bone infections secondary to AIDS.

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 chest radiographic appearances of the non-tuberculous mycobacterial(NTM) pulmonary infection in patients with acquired immune deficiency syndrome (AIDS).Methods Ten patients with AIDS and NTM underwent chest X-ray radiography and 7 patients performed high-resolution CT (HRCT) scan. Chest radiographic features of NTM in patients with AIDS were retrospectively analyzed. Results The chest radiograph showed bilateral pulmonary involvement in 6 cases and single lung involvement in 4 cases (3 cases in the right, 1 case in the left). Patchy air space consolidation (6 cases), large consolidation (5 cases), cavitation (5 cases), small nodules (3 cases),military nodules (2 cases), linear opacity ( 1 cases) were demonstrated on radiography. On HRCT, air space consolidation (7 cases), small nodules (6 cases), large consolidation (5 cases) with cavitation and cylindric bronchiectasis after the absorption of consolidation, enlarged hilar and mediastinal lymph nodes (4 cases), ground-glass opacities (3 cases), military nodules and "tree-in-bud" sign (2 case), pleural effusion ( 1 case), pericardial effusion ( 1 case) and fibrotic band ( 1 case) were found. Conclusion The most common radiographic appearances of NTM in patients with AIDS are bilateral small nodules, large consolidation with cavitation and cylindric bronchiectasis, enlarged hilar and mediastinal lymph nodes.

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.
