“…This aspect is key to distinguishing SPE from other types of pulmonary embolism. The feeding vessel sign [5,6] has been reported in the literature as a characteristic of SPE. In our patient, we performed emergency CT imaging within 24 hours of acute onset, and feeding vessel signs were found.…”

This case report describes the presence of septic pulmonary embolism (SPE) in an older woman with diabetes whose initial manifestation was acute sepsis. She underwent computed tomography (CT) imaging, blood metagenomic next-generation sequencing (mNGS), and bronchoscopy, and was diagnosed with SPE secondary to Staphylococcus aureus-positive bacterial infection, combined with multidrug-resistant pulmonary tuberculosis and bronchial tuberculosis. In this case report, we focused on the clinical presentation and CT imaging features of SPE, and the application value of mNGS. This case study suggests that CT combined with mNGS has value in the timely diagnosis and management of SPE in patients with diabetes with severe pneumonia caused by mixed infection with multiple pathogenic pathogens.

“…Typical CT findings may include nodules and/or cavities located mostly in the area close to peripheral vessel terminations (a sign of feeding vessel; Fig. 2), infiltrates, wedge-shaped lesions adjacent to the pleura, pleural effusion, focal consolidation, and abscess [6][7][8]. The most critical factor for disease prognosis is to consider SPE and start broad-spectrum antibiotic therapy early [3][4][5].…”

Septic pulmonary embolism (SPE) is a rare lung disease that typically occurs when a thrombus containing microorganisms from a nonpulmonary infection focus settles in the pulmonary arteries via the hematogenous route and causes infarction and infection. Nonspecific symptoms such as fever, cough, and chest pain are manifested. SPE is associated with predisposing conditions such as infective endocarditis, intravenous drug addiction, venous catheter, tonsillitis, and tooth and pelvis infections. It has high morbidity and mortality, and the most important point that determines the prognosis is early diagnosis and broad-spectrum antibiotic therapy in the early phase. SPE should be considered when the primary focus of infection is accompanied by high fever and multiple nodules and/or cavitary lesions, which are signs of feeding vessels in the lungs. Here, we present a case of SPE with a hemodialysis catheter and clinical findings of sepsis, which was referred to our center with a preliminary diagnosis of tuberculosis.

“…The feeding vessel sign represents a vessel leading directly to the nodule [ 84 ]. Some studies have found that a “halo sign” and “feeding vessel sign” are more frequent in SPE secondary to Gram-negative bacteria, whereas the cavitation and bronchograms are more common in Gram-positive bacterial embolisms [ 29 ].…”

“…Some studies have found that a “halo sign” and “feeding vessel sign” are more frequent in SPE secondary to Gram-negative bacteria, whereas the cavitation and bronchograms are more common in Gram-positive bacterial embolisms [ 29 ]. The feeding vessel sign, which indicates the hematogenous nature of the nodules, is not specific for septic pulmonary embolism, as this image can be found in other diseases, such as bland pulmonary embolism and hematogenous metastasis [ 29 ], arteriovenous malformation, pulmonary vasculitis and pulmonary infarction [ 84 ]. Multi-detector CT is superior to the classical CT when we want to point up the feeding vessel sign [ 18 ].…”

Nontrombotic pulmonary embolism represents the embolization of different types of materials (cells, organisms, gas, foreign material) into pulmonary circulation. The disease is uncommon, and clinical presentation together with laboratory findings are nonspecific. Its pathology is usually misdiagnosed based on imaging findings as pulmonary thromboembolism, but the correct diagnosis is essential because different therapeutic approaches are required. In this context, knowledge of the risk factors associated with nontrombotic pulmonary embolism and specific clinical symptoms is fundamental. Our objective was to discuss the specific features of the most common etiologies of nontrombotic pulmonary embolism, gas, fat, amniotic fluid, sepsis and tumors, to provide assistance for a rapid and correct diagnosis. Because the most common etiologies are iatrogenic, knowledge of the risk factors could be an important tool for prevention or rapid treatment if the disease develops during different procedures. The diagnosis of nontrombotic pulmonary embolisms represent a laborious challenge, and endeavors should be made to prevent development and increase awareness of this disease.
