In the Western world, liver abscesses are predominantly of pyogenic origin and can present a wide range of ultrasonographic features, from a solid mass to a cystic cavity. Amoebic abscesses are endemic in tropical areas and typically round single lesions. Echinococcal cyst is diagnosed by ultrasound (US). Serology is particularly useful when pathognomonic US features are absent. Treatment is determined based on the WHO ultrasonographic classification, and puncture, aspiration, injection, re-aspiration (PAIR) is a US-guided therapeutic option...

BACKGROUND: Serotype K1 Klebsiella pneumoniae has emerged as an important community pathogen causing various infections, including liver abscesses. Although serotype K1 K. pneumoniae community isolates have been reported as susceptible to most classes of antimicrobial agents, a few cases of infection caused by extended-spectrum beta-lactamase (ESBL)-producing serotype K1 K. pneumoniae have recently been reported in Asian countries. We identified three ESBL-producing strains of serotype K1 K...

Tumefactive demyelinating lesions (TDLs) that may resemble brain neoplasms or abscesses are uncommon but noteworthy. A solid knowledge of how to distinguish TDLs from malignancy or infection is a key step to avoid unnecessary medical or surgical interventions. Almost all the intracranial demyelination diseases after liver transplantation (LT) refer to central pontine myelinolysis or extrapontine myelinolysis; TDLs after LT have never been reported. In 2005, a 45-year-old Chinese male underwent orthotopic LT due to "acute on chronic liver failure" in our hospital...

Bile leakage after duct-to-duct anastomosis in living-donor liver transplantation (LDLT) can mostly be managed by therapeutic endoscopic retrograde cholangiopancreatography. Following this, various complications such as biliary infection, pancreatitis, perforation, and bleeding can occur, and endoscopic sphincterotomy is primarily associated with post- endoscopic retrograde cholangiopancreatography bleeding; other causes have been published in case reports. In the present case, a plastic biliary stent used for treating liver abscesses and leakage at the bile duct anastomosis site after ABO-incompatible LDLT resulted in an intrahepatic artery pseudoaneurysm and hemobilia, which were managed by angiography and coil embolization...

BACKGROUND: Amoebic liver abscess is the most common extra intestinal manifestation of amoebiasis in tropical countries. It usually presents with right hypochondrial pain, fever and anorexia. Amoebic liver abscess has gained clinical significance due to the wide variety of clinical presentations which can cause diagnostic dilemmas and high mortality in untreated cases. CASE PRESENTATION: We report a case of a 63-year-old male with a history of anorexia for 3 weeks, fever for 4 days and examination findings of tender hepatomegaly with a liver span of 15 cm in the mid clavicular line and a firm irregular mass in the right iliac fossa...

Entamoeba histolytica is an enteric pathogen responsible for amoebic dysentery and liver abscess. It alternates between the host-restricted trophozoite form and the infective environmentally-stable cyst stage. Throughout its lifecycle E. histolytica experiences stress, in part, from host immune pressure. Conversion to cysts is presumed to be a stress-response. In other systems, stress induces phosphorylation of a serine residue on eukaryotic translation initiation factor-2α (eIF2α). This inhibits eIF2α activity resulting in a general decline in protein synthesis...

Pyogenic liver abscess (PLA) is a common intra-abdominal infection in adults. In this study, we aim to explore demographic and clinical characteristics of PLA focusing on Klebsiella pneumoniae (K. pneumoniae) induced PLA (KP-PLA) in mainland China. A retrospective review of medical records from all patients with KP-PLA admitted to a tertiary teaching hospital over a 21-year period (1994-2015) was performed. Among 296 PLA cases with confirmed culture-positive data, K. pneumoniae was revealed as the predominant pathogen (n = 189, 63...

We present the case of a 25-year-old male harboring multiple brain lesions mimicking tumor metastasis that were revealed to be caused by Echinococcus multilocularis. Cerebral echinococcosis with multiple lesions is rare and might be confused with a brain abscess, tuberculoma, or metastatic tumor disease. Brain magnetic resonance imaging and serological studies are helpful in the differential diagnosis. In case of E. multilocularis, cerebral invasion is the late stage of the disease that necessitates an aggressive treatment protocol...

Streptococcus intermedius is known to cause periodontitis and pyogenic infections in the brain and liver. Here we report the complete genome sequence of strain TYG1620 (genome size: 2,006,877 bp; GC content: 37.6%; 2,020 predicted ORFs) isolated from a brain abscess in an infant. Comparative genome analysis of S. intermedius genome sequences suggested that TYG1620 carries a notable type VII secretion system (T7SS), two long-repeat regions and 19 ORFs for cell-wall-anchored proteins (CWAPs). To elucidate genes responsible for the pathogenicity of TYG1620, transcriptome analysis was performed in a murine subcutaneous abscess model...

BACKGROUND: The relationship between chronic pancreatitis (CP) and subsequent pyogenic liver abscess (PLA) is not well understood. METHODS: We investigated the risk of PLA in patients with CP using inpatient claims data from the Taiwan National Health Insurance Program for the period 2000-2010, we identified 17,810 patients with chronic pancreatitis (CP group) and 71,240 patients without CP (non-CP group). Both cohorts were followed until a diagnosis of PLA, until they were censored from the study because of loss to follow-up, death, or termination of insurance, or until the study cut-off date of December 31, 2011...

Clostridial soft tissue infections are infrequent, but can be life-threatening when associated with certain underlying conditions, such as immunosuppression or malignancy. When bacteraemia occurs, it can be accompanied by haemolysis. Only surgical removal of the focus of infection and early onset of antibiotic therapy can prevent a very poor outcome. We describe the case of a man aged 65 years who presented with sepsis, haemolysis and rapid worsening. The identification of a gas-forming liver abscess, the early percutaneous drainage and the prompt initiation of antibiotic treatment were the key factors in the outcome of this patient...
