CUEVAS BAILON, Mario A.; ACOSTA FORERO, Manuel; RAMIREZ BUSTOS, Angie  and  WONG AGUILAR, Rosalba. Imaging diagnosis of liver and lung abscesses due to viridans streptococci. Case presentation. Rev. Fac. Med. (Méx.) [online]. 2023, vol.66, n.1, pp.39-46.  Epub May 12, 2023. ISSN 2448-4865.  https://doi.org/10.22201/fm.24484865e.2023.66.1.05.

Streptococcus viridans is more commonly known as an infectious agent in endocarditis, however, little is known about its infectious potential in other organs or systems, where it has shown high mortality. The recognition of Streptococcus viridans as an abscess-producing agent in other locations, such as the liver or lungs, will allow timely diagnosis using different imaging methods, reducing serious consequences for the patient and hospitalization times.

We present the case of a 33-year-old male patient with no chronic degenerative history, who started symptoms 7 months prior to admission, with intermittent fever, fatigue, asthenia, anorexia and weight loss, on physical examination he presented pain at the medium and deep palpation in the right hypochondrium, in the laboratory panel I present striking neutrophilia, in the tomography of the thorax and abdomen a cavernous lesion in the lung and complicated hepatic cysts are shown, to which percutaneous drainage guided by ultrasound is performed, with sending of cultured samples with a positive result for Streptococcus viridans. Thus, allowing treatment to be provided to the patient, thereby achieving remission of the disease.

Keywords : Liver abscess; lung abscess; streptococcal infections; residual abscess; cavitary lung injury; Streptococcus viridans.
