Beaver tail liver is an anatomical liver variant presenting as elongated left lobe of liver which extends laterally to the spleen. It can present with symptoms or be detected accidentally. We present a case of a 2-year-old asymptomatic patient who was had an X-ray of the chest describing a shadow of unknown origin located left paracardial and the diagnosis of “beaver tail liver” was confirmed after a multi-slice computed tomography of thorax and abdomen was done. We give an overview of very sparse available literature on this anatomical variant while emphasizing the rarity of diagnosis in pediatric population and clinical importance of this variant.

Achromobacter xylosoxidans is an aerobic, Gram-negative rod with a broad intrinsic and acquired antimicrobial resistance, usually isolated in patients with cystic fibrosis (CF), immunodeficiencies, or those undergoing invasive procedures. We report a case of a previously healthy 14-year-old girl who was hospitalized in our institution due to a prolonged, progressive cough and exertional dyspnea, which started after a mild viral respiratory tract infection. To elucidate the cause of her symptoms, a bronchoscopy was finally performed, showing bilateral purulent bronchitis caused by A. xylosoxidans, isolated from bronchoalveolar lavage (BAL) sample. Since the patient had positive serological testing for coronavirus disease 2019 (COVID-19), we concluded that it was the initial viral infection, although of a mild clinical course, the one that created favorable conditions for proliferation and further inflammation caused by A. xylosoxidans.
