Gas-forming pyogenic liver abscess (GPLA) is rare and is associated with a high mortality rate. It is commonly associated with underlying diabetes mellitus (DM). Gas formation occurs as a result of mixed acid fermentation within the abscess by formic hydrogenlyase, an enzyme produced by certain bacteria. Presentations can be nonspecific leading to a delay in diagnosis. Management includes urgent drainage of the abscess. We report three cases of GPLA as a result of Klebsiella spp. and Escherichia coli infections. All three patients had DM and were very sick at presentation. Diagnosis was delayed in one patient and this likely contributed to his death. Hospitalisations were prolonged. These cases highlight the need to consider GPLA in diabetic patients presenting with fever, abdominal pain, nonspecific symptoms or septic shock.

Simultaneous Klebsiella pneumoniae and amoebic liver abscess is rarely reported in immunocompetent patients. A 47-year-old man was hospitalized with abdominal pain, fever, chills, and hypotension. Physical examination revealed right upper quadrant tenderness. Abdominal computed tomography showed an area of low attenuation with some liquefaction in the liver. Echo-guided aspiration revealed 30 mL of pus, which grew Klebsiella pneumoniae, and the same organism was isolated from the blood. Cytology examination of the pus showed scattered amoeba. The patient gradually improved over 1 month on treatment with cefmetazole and metronidazole, along with repeated drainage of the abscess. His amoebic indirect hemagglutination titer was 1:128, but no parasite ova or amoeba were found in the stool. He had no evidence of immunocompromise. Parasitic diseases may be a predisposing factor for bacterial infections, including pyogenic liver abscess. The possible coexistence of amoebae and bacteria in a liver abscess should not be discounted.

A 63-year-old woman was admitted for cholecystitis and underwent a laparoscopic cholecystectomy (LC). She experienced abdominal pain and hemobilia 11 days after the LC. Angiography was performed but it did not show any source of bleeding. Thereafter, at 27 days after LC, a repeat angiogram was performed which revealed a pseudoaneurysm (PA) arising from a cystic artery stump and an embolized PA sack. However, another PA arising from near the embolized PA and liver abscess was observed 4 days after embolization. The arterial collateral flow was evaluated by endovascular balloon occlusion of the right hepatic artery and it was embolized proximal and distal to the bleeding point. The embolization of the partial hepatic artery was effective for PA when packing the PA sack proved to be insufficient. In patients with liver cirrhosis or liver abscess who require an adequate arterial liver flow, it is important to evaluate the collateral arterial flow before hepatic artery embolization.

Pyogenic liver abscess is an unusual cause of fever and abdominal pain, but it is potentially fatal. It is rarely caused by a local event, but rather by hematogenous dissemination or biliary tract disease. We report an uncommon case of liver abscess caused by the migration of a fish bone through the gastrointestinal wall.

A 57-year-old man was admitted to our hospital because of dyspnea and right abdominal pain. Chest X-ray radiogram showed right massive pleural effusion. Ultrasonic echogram of abdomen showed a unilocular liver cyst. He was treated with intravenous infusion of meropenem, and percutaneous pleural and liver drainage were performed. At the time of drainage, we injected contrast medium into the liver cyst and confirmed a fistula connecting to the right pleural space. Initially we made a diagnosis of bacterial empyema and liver abscess, yet there was no response to the initial treatment. Cultures of pleural effusion and liver abscess were confirmed to be negative. A few days after admission, the patient stated that he was a homosexual. Liver amebiasis and its perforation became the most likely diagnosis, and metronidazole was administered. On admission day 21, tests for anti-amebic antibody were positive. Finally he fully recovered. We must be aware of the rare pulmonary manifestation of amebiasis. We report this case and review the literature.

We here present an interesting unusual case of upper abdominal pain. The patient was a 38-year-old man, who was admitted to our hospital complaining of right upper quadrant pain caused by a toothpick that perforated the anterior gastric wall and penetrated segment I of the liver. After endoscopic removal and an initially uneventful course, computed tomography revealed a perigastric abscess that was treated by repeated gastroscopic rinsing via an endoscopically placed catheter. After another three uneventful weeks, a liver abscess with minor tendency to constrict the portal vein was diagnosed, and a segment I liver resection together with abscess drainage was performed. The peculiarity of this case is the rarity of toothpick ingestion and gastric perforation in a young and healthy white Caucasian followed by development of a liver abscess after primary uneventful endoscopic removal. In light of this case, gastric perforation due to ingested foreign bodies such as toothpicks can be considered a rare cause of upper abdominal pain.

Amebic colitis is common in developing countries, with its variable and non-specific symptoms. Amebomas occur rarely, resulting from the formation of annular granulation tissue, usually in the cecum and in the ascending colon. This report describes the case of a 59-year-old male who presented with abdominal pain. Radiological examination depicted concentric thickening of the cecal wall with mass formation and a cystic lesion in the liver. The endoscopy performed showed a growth in the ascending colon. Biopsy revealed extensive necrosis and inflammatory cells. The patient was referred to this hospital for surgical treatment with a provisional diagnosis of carcinoma of the colon. Peroperatively, a cecal mass was identified. However, suspected secondaries were not seen on the surface of the liver. Histological examination of the right hemicolectomy specimen revealed cecal and ascending colon amebomas. Trophozoites of Entamoeba histolytica were better recognized after periodic acid-Schiff staining. Treatment with Metronidazole for 2 weeks followed by diloxanide furoate for an additional 2 weeks was administered. The liver lesion resolved completely after 8 weeks. Colonic ameboma accompanied by amebic liver abscess may be misdiagnosed as metastatic colon cancer. A high index of suspicion is essential for diagnosis when dealing with colonic masses and liver lesions, especially in the tropics.

A 58-year-old male patient with an unresectable 10 cm liver lesion that was a histologically proven hepatocellular carcinoma (HCC) underwent transcatheter hepatic artery embolisation (TAE). 4 months later, the patient was referred for salvage radiotherapy owing to local recurrence. The HCC became an encapsulated tumour with central necrosis after radiotherapy. The patient enjoyed a normal lifestyle for 9 years, with local control achieved by radiotherapy, until a hepatogastric fistula developed. Although the hepatogastric fistula resolved with surgical drainage, the patient later died from septic shock. Hepatogastric fistula is a rare but serious complication after TAE and radiotherapy for HCC. Development of fever, abdominal pain and jaundice after an initial symptom-free interval should arouse suspicion of hepatogastric fistula formation from an encapsulated necrotic HCC or a ruptured liver abscess. Because the mortality is high, aspiration of a suspected necrotic lesion should be performed as soon as possible. Patients with risk factors, including liver cirrhosis and large lesions close to the adjacent gastrointestinal tract, are especially vulnerable. Gas formation within a necrotic liver tumour requires immediate drainage.

A 72-old-year Japanese man was incidentally found to have out liver dysfunction on serum examination and a cystic tumor in the liver. Dynamic computed tomography revealed a solitary cystic tumor 14 cm in diameter with multiple septa. The cyst wall was occasionally irregular with hyperarterial inflow. After admission, he suffered from fever and right upper abdominal pain. We suspected cystadenocarcinoma with intraluminal infection. Percutaneous transhepatic drainage was performed. However, neither cytologic examination nor culture test was positive. The cystic tumor had been decreasing in size, and hepatic resection performed. Macroscopically, the tumor was a gray-yellow solid tumor with a fine boundary between tumor and liver parenchyma, and the cystic lesion collapsed. Microscopically, the tumor consisted of hepatic infarction, degenerated Glisson's sheath, and chronic inflammation, and chronic liver abscess was diagnosed. Most cases of bacterial liver abscess can be diagnosed because progression is accompanied by typical signs. However, it is difficult to diagnose liver abscess in the chronic phase because chronic liver abscesses exhibit various features on imaging series without typical signs or symptoms. When atypical liver cyst is found, the possibility of liver abscess in chronic phase should be considered.

There are few studies reporting pyogenic liver abscess (PLA) caused by Streptococcus constellatus in the medical literature. S. constellatus is a comensal microorganism that belongs to the Streptococcus milleri's bacteria group and is not considered to be pathogenic for humans. We report the case of a 23-year-old man with a 15-days history of abdominal pain in the right flank followed by daily fever, chills, nausea, vomits, sialism and jaundice. Physical examination revealed moderate jaundice (2+/4+), abdominal distention, generalized pain and tender over the right flank with positive Blumberg's sign. Additionally, the liver was palpable 5 cm below the costal margin in the right midclavicular line. Abdominal Computerized Tomography showed multiple hypodense hepatic images suggestive of liver abscesses. The patient underwent surgical exploration of the abdomen through a sub-costal incision and, during operation ruptured abscess localized on the hepatic segment III was drained. Culture of the purulent material obtained at surgery yielded Streptococcus constellatus as the causative agent. Liver abscess is a potential life-threatening disease that must be treated as soon as possible with invasive approaches, if necessary, and bacteriological studies performed when possible, allowing isolation of causative agents and specific antibiotic therapy.
