We report the case of a 21 years old male patient, with a history of asthma since the age of 8 months, without follow-up, presenting a severe respiratory distress appeared suddenly, associated with a right basithoracic pain, and moderate hemoptysis. The non-contrast CT-chest scan showed a basal ground-glass opacity of the right lung leading to suspicion of Covid 19s’ pneumonia. Laboratory tests reveal an elevated levels of D-dimers (D-D), a thrombocytopenia, a neutrophilic leukocytosis and a hyper eosinophilia. The molecular test RT-PCR is negative. With the persistence of the right-side basithoracic pain and the presence of a hyper eosinophilia and increased levels of D-Dimers. A thoracic CT angiography was indicated that shows a bilateral distal pulmonary embolism with a right-sided basal sub segmental ischemia. We discuss a fortuitous discovery of an idiopathic pulmonary embolism associated to peripheral basal ground-glass opacities similar to the radiological findings found in the case of a SARS-Cov-2 pneumonia.

Background: A saddle pulmonary embolism (PE) is a large embolism that straddles the bifurcation of the pulmonary trunk. This PE extends into the right and left pulmonary arteries. There is a greater incidence in males. Common features of a PE include dyspnea, tachypnea, cough, hemoptysis, pleuritic chest pain, tachycardia, hypotension, jugular venous distension, and severe cases Kussmaul sign. The Wells criteria for PE is used as the pretest probability. Diagnostics include D-dimer levels, CT pulmonary angiography (CTPA), ventilation/perfusion scintigraphy (V/Q scan), echocardiography, lower extremity venous ultrasound, chest x-ray, pulmonary angiography, and electrocardiography (ECG). Case description: We present a 65-year-old male that presented with a two-week history of dyspnea with non-radiating intermittent chest pressure. Initial V/Q scan showed a low probability for PE, but a subsequent non-contrast CT revealed that he indeed had a saddle PE.

During the first weeks of the SARS-CoV-2 pandemic in Honduras, a 66-year-old female patient was admitted to the ICU with a 5-day history of cough, fever, and respiratory distress. She had contact with a COVID-19 patient in previous days. The chest radiograph showed signs of bilateral ground-glass opacities (A). Since the RT-PCR was negative, a computed tomography angiography was done at day 7 to rule out a pulmonary embolism. This showed a diffuse, patchy, bilateral increase in density with ground-glass opacities, poorly defined edges, and slight predominance in subpleural regions (B and C). There was no evidence of a pulmonary thromboembolism. The swab test was repeated at day 7, resulting positive. In this case, the clinical and CT findings were highly suggestive before RT-PCR confirmed the diagnosis. This is the first COVID-19 case with a false negative PCR test in our hospital. She recovered fully.

BACKGROUND The computerised tomography (CT) characteristics of COVID-19 are reported and compared with the CT characteristics of other viruses to familiarise radiologists with potential CT trends and to determine the effectiveness of chest CT in the diagnosis and treatment of COVID-19. METHODS This was a hospital based descriptive study which involved the first 324 patients with a finding of severe acute respiratory syndrome (SARS-CoV-2) infection validated by real-time reverse transcription-polymerase chain reaction (RT – PCR). Monitoring patients (198 males, 126 females with a mean age of 46.50 years ± 8.96 [SD] and age range of 21 - 76 years) from April 2020 to July 2020. We correlated the image reports from the initial CT analysis with the findings of the laboratory studies and established possible CT patterns for viral infection. RESULTS The initial chest CT studies of the 324 SARS-CoV-2 patients showed that the disease affected all 'five lobes' in 248 (76.54 percent) patients, both 'lower lobes' in 49 (15.12 percent) patients, the right lower lobe in 23 patients (7.10 percent), and the left lower lobe and right middle lobe in 2 patients (0.62 percent). In 303 (93.52 percent) patients, the lesions were primarily peripheral and subpleural; and there were fewer lesions along the bronchovascular bundles. Two major patterns of SARS-CoV-2 lesions on CT images are GGO (ground - glass opacity) and consolidation. In 303 of the 324 patients (93.52 percent), CT showed single or multiple abnormal GGO or consolidation, or both. In the remaining 21 (6.48 percent) cases, neither GGO nor consolidation was observed on CT. Follow-up CT showed moderate or pronounced disease worsening in 12 out of 58 (20.69 percent) cases and follow-up CT showed improvement with the appearance of fibrosis and GGO resolution. CONCLUSIONS In conclusion, the use of a chest CT system in SARS-CoV-2 patients can accurately evaluate pneumonia. Most notably follow-up CT scans may help assess patients with SARS-CoV-2 pneumonia in their response to treatment. KEYWORDS SARS-CoV-2, Pneumonia, Chest Computed Tomography, Ground-Glass Opacities

Abstract Background To emphasize the importance of CT in the diagnosis of COVID-19 disease by comparing the thoracic CT findings of COVID-19 patients with positive RT-PCR results and patients with clinical suspicion of COVID-19 but with negative RT-PCR results. Results In our study, COVID-19 patients with positive RT-PCR results (RT-PCR (+) group) and patients with clinical suspicion of COVID-19 but negative RT-PCR results (RT-PCR (−) group) were compared in terms of CT findings. In CT images, ground-glass opacity and ground-glass opacity + patchy consolidation were the most common lesion patterns in both groups. No statistically significant differences in the rates and types of lesion patterns were observed between the two groups. In both groups, lesion distributions and distribution patterns were similarly frequent in the bilateral, peripheral, and lower lobe distributions. Among the 39 patients who underwent follow-up CT imaging in the first or second month, a regression in lesion number and density was detected in 18 patients from both groups. Consolidations were completely resorbed in 16 of these patients, and five patients had newly developed fibrotic changes. The follow-up CT examination of 16 patients was normal. Conclusions Due to the false-negative rate of RT-PCR tests caused by various reasons, clinically suspected COVID-19 patients with a contact history should be examined with CT scans, even if RT-PCR tests are negative. If the CT findings are positive, these patients should not be removed from isolation.

Abstract Introduction Corona virus disease (COVID-19) pandemic can cause myriad of ocular manifestations. We report a case of unilateral multi focal central serous retinopathy, post COVID-19 infection in an Asian Indian female. Case presentation A 42-year-old female presented to us with unilateral blurring, in the right eye (OD), 12 days after COVID-19 infection. She had fever, chills, shortness of breath and cough with tiredness and was COVID- RT PCR positive. She was administered intravenous and oral antibiotics with injection heparin/remdesivir, during her 7 day stay at the hospital. She was also on steroid inhalers. She had no systemic history of note. On ocular evaluation, her corrected distance visual acuity was 20/40 in OD and 20/20 in left eye (OS). Anterior segment was normal. Anterior vitreous was clear. Fundus examination of the OD showed central serous retinopathy (CSCR) with OS being normal. Conclusion CSCR can occur post COVID-19 due to steroid administration and physicians administering it should be aware of this and refer the patients to an ophthalmologist earlier.

Abstract Background To evaluate the diagnostic performance of chest CT in differentiating coronavirus disease 2019 (COVID-19) and non-COVID-19 causes of ground-glass opacities (GGO). Results A total of 80 patients (49 males and 31 females, 46.48 ± 16.09 years) confirmed with COVID-19 by RT-PCR and who underwent chest CT scan within 2 weeks of symptoms, and 100 patients (55 males and 45 females, 48.94 ± 18.97 years) presented with GGO on chest CT were enrolled in the study. Three radiologists reviewed all CT chest exams after removal of all identifying data from the images. They expressed the result as positive or negative for COVID-19 and recorded the other pulmonary CT features with mention of laterality, lobar affection, and distribution pattern. The clinical data and laboratory findings were recorded. Chest CT offered diagnostic accuracy ranging from 59 to 77.2% in differentiating COVID-19- from non-COVID-19-associated GGO with sensitivity from 76.25 to 90% and specificity from 45 to 67%. The specificity was lower when differentiating COVID-19 from non-COVID-19 viral pneumonias (30.5–61.1%) and higher (53.1–70.3%) after exclusion of viral pneumonia from the non-COVID-19 group. Patients with COVID-19 were more likely to have lesions in lower lobes (p = 0.005), peripheral distribution (p < 0.001), isolated ground-glass opacity (p = 0.043), subpleural bands (p = 0.048), reverse halo sign (p = 0.005), and vascular thickening (p = 0.013) but less likely to have pulmonary nodules (p < 0.001), traction bronchiectasis (p = 0.005), pleural effusion (p < 0.001), and lymphadenopathy (p < 0.001). Conclusions Chest CT offered reasonable sensitivity when differentiating COVID-19- from non-COVID-19-associated GGO with low specificity when differentiating COVID-19 from other viral pneumonias and moderate specificity when differentiating COVID-19 from other causes of GGO.

Abstract Background Catamenial pneumothorax is characterized by spontaneous recurring pneumothorax during menstruation, which is a common clinical manifestation of thoracic endometriosis syndrome. There are still controversies about its pathogenesis. Case presentation A 43-year-old woman with a history of endometriosis came to our hospital due to recurring pneumothorax during menstruation. Uniportal Video-assisted Thoracoscopic Surgery (VATS) exploration was performed on the eve of menstruating. We thoroughly explored the diaphragm, visceral and parietal pleura: The lung surface was scattered with yellowish-brown implants; no bullae were found; multiple diaphragmatic defects were found on the dome. And surprisingly, we caught a fascinating phenomenon: Bubbles were slipping into pleural cavity through diaphragmatic defects. We excised the diaphragmatic lesions and wedge resected the right upper lung lesion; cleared the deposits and flushed the thoracic cavity with pure iodophor. Diaphragmatic lesions confirmed the presence of endometriosis, and interestingly enough, microscopically, endometrial cells were shedding with impending menses. After a series of intraoperative operations and postoperative endocrine therapy, the disease did not recur after a period of follow-up. Conclusion We have witnessed the typical signs of catamenial pneumothorax at the accurate timing: Not only observed the process of gas migration macroscopically, but also obtained pathological evidence of diaphragmatic periodic perforation microscopically, which is especially precious and confirms the existing theory that retrograde menstruation leads to diaphragmatic endometriosis, and the diaphragmatic fenestration is obtained due to the periodic activities of ectopic endometrium.

A 13-year-old female patient with refractory primary congenital glaucoma (PCG) in the right eye who had a history of multiple glaucoma operations underwent ab interno 180-degree trabeculectomy with the Kahook Dual Blade (KDB) targeting the nasal and inferior angles. On postoperative day 1, the intraocular pressure (IOP) of the right eye reduced from 43 to 15 mmHg while on medical therapy. The patient maintained this IOP level throughout the 6-month follow-up. Ab interno KDB trabeculectomy targeting both nasal and inferior angles may be an effective and safe procedure for the treatment of PCG even in eyes with a history of previously failed glaucoma procedures.
