Invasive pyogenic spondylitis with retropharyngeal and hepatic abscesses caused by hypermucoviscous klebsiella pneumoniae: A radiologic case report

Hypermucoviscous Klebsiella pneumoniae (HmKP) is an emerging pathogen with strong invasive potential, particularly in immunocompromised patients. We present the case of an 84-year-old man with type 2 diabetes mellitus who developed systemic infection including liver abscess, retropharyngeal abscess, and cervical pyogenic spondylitis caused by HmKP. Despite clinical improvement with appropriate antibiotics, follow-up MRI demonstrated vertebral collapse. This case highlights the necessity of radiological follow-up in patients with HmKP infections.
