“…Radiological features are different in influenza pneumonia compared with COVID-19 and pneumomediastinum is believed to be a much less frequent complication (or never occurs) in COVID-19 pneumonia. 31,32,35,37,57 By contrast, our case report indicates that it may occur, albeit this complication may have been favored by HFNC and other conditions.…”

“…Spontaneous pneumomediastinum is defined as air in the mediastinum without evident causes (eg, traumatic, iatrogenic, hollow organ perforation, gas‐producing infection surgery, or any other interventions) 8 . Numerous reports 24‐56 have demonstrated that several lung infections, mainly influenza, provoke pneumomediastinum.

“…Although pneumomediastinum was reported as a complication of several lung infections, 24‐56 it is possible that alterations induced by SARS‐CoV‐2 infection are more complex. For instance, SARS‐CoV‐2 infects both type I and II pneumocytes, and this may cause damage of the integrity of the alveolar membrane, which may lead to alveolar rupture 8 .…”

“…The 25 papers described larger cohorts of patients for a total of 2985 patients with rickettsial diseases, and among these patients, 487 (15.97%) suffered from pleural effusion. Only in 4 of these, molecular techniques were performed to achieve the etiological diagnosis [53][54][55]; the diagnosis was made by microscopic observation of morulae within the cytoplasm of polymorph-nucleate-cells only once [56]; in the other 23 case series, the diagnosis was made by serological assays [52,53,55,[57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73]. In the last 25 years in Europe, there was only one report of pleural effusion associated with a rickettsial disease.…”

Background: Motivated by a case finding of Mediterranean spotted fever (MSF) associated with atypical pneumonia and pleural effusion in which Rickettsia conorii subsp. israelensis was identified by molecular methods in the pleural fluid, we wanted to summarize the clinical presentations of rickettsiosis in Italy by systematic research and to make a systematic review of all the global cases of rickettsiosis associated with pleural effusion. Methods: For the literature search, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology was followed. We chose to select only the studies published in last 25 years and confirmed both with serological and molecular assays. Results: Human cases of rickettsiosis in Italy were reported in 48 papers describing 2831 patients with very different clinical presentations; the majority was MSF accounted to R. conorii and was reported in Sicily. Pleural effusion associated with infection with microorganisms belonging to Rickettsiales was described in 487 patients. It was rarely associated with microorganisms different from O. tsutsugamushi; also rarely, cases of scrub typhus were reported outside Southeast Asia and in the largest majority, the diagnosis was achieved with serology. Conclusions: MSF, especially when caused by R. conorii subsp. israelensis, may be a severe disease. A high index of suspicion is required to promptly start life-saving therapy. Pleural effusion and interstitial pneumonia may be part of the clinical picture of severe rickettsial disease and should not lead the physician away from this diagnosis

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by SFTS virus (SFTSV) which involves multiple organ systems, including lungs. However, there is limited data on lung involvement of SFTS. Therefore, the present study investigated the chest radiographic findings of SFTS, including computed tomography (CT), and compared these with those of scrub typhus, which is the most common tick-borne illness in South Korea and share risk factors and occur in similar settings. Medical records of patients with confirmed SFTS and scrub typhus in a tertiary hospital in Seoul (South Korea), between January 2014 and June 2018, were reviewed. Initial chest radiography and CT were reviewed by 2 experienced radiologists. A total of 39 patients with SFTS and 101 patients with scrub typhus were analyzed. All patients except 3 patients with scrub typhus in both groups received chest radiography. Cardiomegaly (90%) and patchy consolidation with ground glass opacity (GGO) pattern (31%) were more common in SFTS group than scrub typhus group (20%, P < .001 and 2%, P < .001, respectively). About half of each group received chest CT. Consolidation (29%) and pericardial effusion (24%) were more common in SFTS group than scrub typhus group (6%, P = .02 and 4%, P = .008, respectively). Interstitial thickening in chest radiography (58%) and chest CT (65%) was more frequent in scrub typhus group than SFTS group (18%, P < .001 and 19%, P < .001, respectively). Cardiomegaly with/without pericardial effusion and patchy consolidation with GGO pattern were more frequent in SFTS group, whereas interstitial thickening was more frequent in scrub typhus group. These findings will assist the early differentiation of SFTS from scrub typhus.
