Hypermucoviscous Klebsiella pneumoniae liver abscess requiring liver resection

Description 

A 41-year-old healthy woman from China presented to her local hospital with a 4-day history of fevers, malaise and epigastric pain. On examination, she had localised right upper quadrant abdominal pain on palpation. Laboratory investigations showed leukocytosis (13.8x10⁹/L), thrombocytopaenia (82x10⁹/L) and elevated alanine transaminase (184 U/L). An abdominal CT scan revealed a 10x8x9 cm multiloculated collection within the right liver lobe, with a second nodular septated collection under the left subcapsular region (figure 1). Her blood cultures returned positive for Klebsiella pneumoniae, resistant to ampicillin and susceptible to cefazolin, ciprofloxacin and meropenem. She was admitted to hospital and started on ceftriaxone.
