Chest computed tomographic findings of patients with COVID-19-related pneumonia

Background In December 2019, pneumonia cases of unknown cause were announced in Wuhan, China. The causative agent of pneumonia was identified as coronavirus 2 (SARS-CoV-2), and the disease was named coronavirus disease 2019 (COVID-19). Purpose To evaluate the usefulness of computed thoracic tomography (CT) and postero anterior (PA) thoracic radiography in patients with COVID-19. Material and Methods Between March and June 2020, the patients who arrived at our hospital with suspicion of COVID-19 were retrospectively analyzed. Thorax CT findings of the 281 patients (142 females and 139 males; age range 3–91 years) with positive PCR tests were evaluated. Lesions in the lung parenchyma were examined according to their number, localization, and distribution. PA chest radiograms were classified into two groups, positive and negative for the lung parenchymal lesions. Results Of the total 281 patients with PCR-positive COVID-19, CT examinations were normal in 107 (38.1%), and positive CT findings for pneumonia were found in 174 patients (61.9%). Bilateral involvement was observed in 100 (57.5%) of the 174 patients with positive CT findings, and unilateral involvement was observed in 74 (42.5%) of them. According to the localization of the lesions, peripheral subpleural distribution occurred in 160 of the 174 patients (91.9). The most common lesion was the ground glass opacities (GGO). In 77 of 281 PCR-positive patients (27.4), pulmonary lesions were found on PA chest radiograms. Conclusion The presence of bilateral posterior subpleural GGO, nodule, and consolidation in thoracic CT are significant in terms of COVID-19 pneumonia.

BACKGROUND: The therapeutic response to endobronchial tuberculosis is usually evaluated by bronchoscopy. Currently, there are no published studies investigating the use of computed tomography for the evaluation of therapeutic response in endobronchial tuberculosis.OBJECTIVE: A retrospective study was performed to evaluate the bronchoscopic and computed tomographic features of endobronchial tuberculosis before and after treatment. The aim of this study was to investigate the usefulness of computed tomography for the assessment of treatment.METHODS: The clinical, pathological and bronchoscopic features of endobronchial tuberculosis were evaluated in 55 patients. The age range of the patients was 21 to 52 years. Computed tomography and bronchoscopy were performed before and after treatment.RESULTS: Diagnosis of tuberculosis was confirmed by culture and histopathological examination. Bronchoscopic examination revealed 89 endobronchial lesions of various types in 55 patients. The exudative type was the most common. Follow-up bronchoscopy revealed that exudative-, ulcerative- and granular-type lesions healed completely. Computed tomography performed after treatment correlated well with the follow-up bronchoscopic findings.CONCLUSION: The results suggest that follow-up computed tomography is useful for the evaluation of therapeutic response and complications associated with endobronchial tuberculosis, and may replace bronchoscopy.

A 4-month old, male intact, mixed-breed dog was referred for sudden onset of regurgitation for two weeks. Thoracic radiographs revealed severe dilatation of esophagus with barium aspiration pneumonia. Idiopathic megaesophagus (IME) was diagnosed after serial laboratory, endoscopic and computed tomographic examinations. Symptomatic treatment including medication for pneumonia, feeding through percutaneous endoscopic gastrostomy (PEG) tube with upright feeding position was performed at first, but regurgitation persisted. Sildenafil (1[Formula: see text]mg/kg, PO, BID) was then administrated for two weeks and regurgitation remitted one day after. Sildenafil was then tapered to half dose (0.5[Formula: see text]mg/kg, PO, BID) for another two weeks. During following-up thoracic radiography on 10 days after sildenafil administration, the degree of esophagus dilation significantly reduced. The clinical sign was completely resolved without relapse for more than 300 days. Sildenafil was reported having inhibitory effect of canine gastric contraction without affecting gastric emptying time. This effect could ameliorate persisting regurgitation after using PEG feeding directly into the stomach while bypassing the esophagus.

Stent Stenosis

It is unclear whether cilostazol instead of aspirin in combination with clopidogrel could prevent in-stent thrombosis in patients with a history of gout undergoing vertebral artery origin stenting. Three men (age range, 58–74 years) were diagnosed with acute ischaemic stroke or transient ischaemic attack. Vertebral artery origin stenosis was visible by computed tomographic angiography or digital subtraction angiography. Four bare metal stents were placed in the vertebral artery origin. The patients were administered 100 mg cilostazol orally twice a day and 75 mg clopidogrel orally once a day perioperatively and 100 mg cilostazol orally twice day was administered indefinitely after 3 months. No in-stent stenosis was observed in all of these patients during a follow-up period up to 19 months. Cilostazol plus clopidogrel has the potential to become an alternative to standard dual antiplatelet therapy in vertebral artery origin stenting. A high-quality clinical trial is needed to verify these preliminary findings.

Abstract The relationship between the results of early operation for ruptured intracranial aneurysms (72 cases) and the preoperative computed tomographic (CT) findings was studied. There was a correlation among the surgical results, the development of symptomatic vasospasm, and high density on the preoperative CT scan, particularly the presence of a localized, thick layer in the subarachnoid space. However, no relationship was found between the occurrence of ventricular enlargement and the preoperative CT findings. Cisternal or ventricular drainage might contribute to an uncomplicated postoperative course for patients with severe subarachnoid clot shown on the preoperative CT scan.
