“…A similar sonographic characteristic described as the "fluid rim sign" was reported in a case report of musculoskeletal aspergillosis [14]. For hepatosplenic mycotic abscesses the "wheel within wheel" appearance is described as a specific finding on ultrasound [14].…”

“…A publication on endobronchial ultrasound from 2016 reports a "central annular image in an ill-defined hypoechoic paraoesophageal lesion" as possibly sonographic characteristic of pulmonary aspergillosis [13]. A similar sonographic characteristic described as the "fluid rim sign" was reported in a case report of musculoskeletal aspergillosis [14]. For hepatosplenic mycotic abscesses the "wheel within wheel" appearance is described as a specific finding on ultrasound [14].…”

Purpose Pulmonary aspergilloma affects immunocompromised patients but is also a recurrent condition in patients previously treated for pulmonary tuberculosis. Methods and Results We report the case of a 45-year-old patient with a history of cured pulmonary tuberculosis 15 years earlier in whom we visualized pulmonary aspergilloma by transthoracic lung sonography. Sonography of pulmonary aspergilloma demonstrated an oval cavity with hypoechoic contents and an irregular border, measuring a diameter of 4.7 cm; inside the lesion, a roundish structure with an anechoic rim was discernable. Conclusions The sonographic findings corresponded to chest X-ray and computed tomography imaging in this patient and to previously reported sonographic characteristics of mycotic abscesses in other organs. Lung ultrasound may be a tool to identify pulmonary aspergilloma, especially as a point-of-care imaging tool and where other imaging modalities are inaccessible.

“…Human diseases associated with gas-producing A. fumigatus, such as emphysematous renal tract disease, have been described before [31]. In addition, A. fumigatus-specific shadowing using sonography was also traceable in a soft tissue infection with appearance of a necrotic core surrounded by air [32]. Finally, sonographic investigation of patients infected with A. fumigatus also showed gas infiltrative shadows (own observation) which have also been described as transient radiographic shadows in the lung by X-ray [33].…”
