case_images: String test result for Klebsiella pneumoniae. Stretching of K. pneumoniae colonies isolated from our patient's sample resulted in the formation of a string >5 mm in length, demonstrating the hypermucoviscosity phenotype.

case_images: Hypermucoviscous phenotype was confirmed by a positive string test: formation of viscous strings >= 5 mm in length when a standard bacteriologic loop was used to stretch the colony on agar plate Fig. (1).

case_images: Abdominal computed tomography (CT) scan with double contrast showed a 15 cm hypodense lesion with internal septa in the liver Fig. (2a), and a hypodense tumour-like lesion with narrowing of the gastric lumen Fig. (2b).

case_images: The latter was further investigated by endoscopy-ultrasound (EUS), which showed a 3-cm well-circumscribed hypoechoic submucosal mass suggestive of intramural gastric abscess Fig. (3a,b).  Chest x-ray, transthoracic echocardiography and abdominal Doppler ultrasound were normal.

case_images: All strains from different isolation sites were serotype K1 by PCR and had identical profile by PFGE Fig. (4).
