Medical Case Report Accurately Describes Pyogenic Liver Abscess Symptoms
“Introduction This case report examines the diagnostic progression, laboratory interpretation and clinical reasoning that led to the identification of a pyogenic liver abscess secondary to ascending cholangitis caused by choledocholithiasis in a 62‑year‑old male. In accordance with confidentiality and data protection standards, the patient is not named, age and sex alone do not constitute identifiable information under GMC Good Medical Practice or GDPR. The case demonstrates the importance of structured diagnostic reasoning in hepatobiliary disease, where overlapping symptoms can obscure the underlying pathology. By integrating clinical presentation with sequential laboratory and imaging investigations, the report highlights how biliary obstruction can progress to severe infection and hepatic abscess formation if not promptly recognised and treated. Patient Presentation The patient, a 62 year old male, presented with several weeks of right upper quadrant abdominal pain radiating to the right shoulder. He reported pale stools, pruritus, fatigue and intermittent fever. These symptoms strongly suggested impaired bile flow, as pale stools indicate reduced stercobilin due to diminished biliary excretion, while pruritus is commonly associated with cholestasis. On examination, the patient was hypotensive and tachycardic, with rebound tenderness in the right quadrant. The combination of abdominal pain, jaundice and fever raised immediate concern for biliary pathology, while the haemodynamic instability suggested progression to systemic infection or sepsis. The chronicity of symptoms, followed by acute deterioration, implied an evolving obstructive process with secondary infection. The initial clinical impression included the possibility of gallstone disease, particularly cholecystitis or choledocholithiasis, given the pain and pale stools. However, the severity of systemic features required a broad differential diagnosis and urgent investigation. Initial Differential Diagnosis The initial differential diagnosis included several hepatobiliary, pancreatic, cardiac and infectious conditions. Viral hepatitis was considered due to the presence of jaundice and RUQ discomfort, but the patient’s systemic instability and absence of prodromal viral symptoms made this less likely. Drug‑induced hepatitis was also considered; however, the patient reported no recent medication use, and drug‑induced liver injury typically presents with hepatocellular rather than cholestatic patterns. Acute pancreatitis was included in the differential due to the anatomical proximity of the pancreas to the biliary tree and the possibility of gallstone‑induced pancreatitis. However, pancreatitis usually presents with epigastric pain radiating to the back rather than the shoulder, and pale stools are less characteristic. Myocardial infarction was considered because cardiac ischaemia can present with atypical abdominal pain in older adults, but the presence of jaundice and pale stools made a cardiac cause unlikely. Simple acute cholecystitis was a plausible diagnosis, as it presents with RUQ pain, fever and leukocytosis. However, pale stools and pruritus are not typical features, and the degree of systemic instability suggested a more severe process. Acute cholangitis was strongly considered due to the classical Charcot’s triad of RUQ pain, jaundice and fever. The patient’s hypotension and tachycardia also suggested progression towards Reynolds’ pentad, indicating severe cholangitis with sepsis. Malignancy, including pancreatic cancer or cholangiocarcinoma, was included due to the patient’s age and the presence of obstructive jaundice. However, the acute deterioration and systemic inflammatory response were more consistent with infection than malignancy. At this stage, the working differential diagnosis prioritised acute cholangitis, choledocholithiasis, gallstone related obstruction, and possible hepatic abscess formation. To refine the differential and identify the source of sepsis, first‑line laboratory investigations were urgently required. Following the initial clinical assessment, a comprehensive panel of first‑line investigations was requested to refine the differential diagnosis and identify the source”
Summary
Medical literature confirms that pyogenic liver abscesses can develop as a complication of ascending cholangitis caused by biliary obstruction such as choledocholithiasis, and the described clinical features and risk factors match established knowledge. The claim that age and sex alone are non‑identifiable under GDPR and GMC guidance is not supported by the provided sources.

However, a normal abdominal sonogram does not necessarily rule out ascending cholangitis. Abdominal computed tomography (CT) can be performed as an adjunct to investigate co-existing pathologies such as hepatic/pancreatic tumors, metastasis, or hepatic abscess.[20] Dilated intrahepatic and extrahepatic ducts, as well as inflammation of the biliary tree, can be appreciated.

However, direct cholangiography can exacerbate the cholangitis leading to severe sepsis and should always be combined with therapeutic drainage procedure whenever biliary obstruction is demonstrated. Poor prognostic factors include old age, female sex, acute renal failure, concomitant medical problems, pH < 7.4, bilirubin > 90 μmol/L, albumin < 30 g/L, platelet count < 150 × 109/L, preexisting cirrhosis, presence of liver abscess and malignant biliary obstruction.

The majority of these abscesses are categorized as pyogenic or amoebic, although a minority are caused by parasites and fungi. Although the incidence of liver abscess is low, it is essential to early detect and manage these lesions, since there is a significant mortality risk in untreated patients.

Poor prognostic factors in the setting of acute cholangitis include old age, high fever, leukocytosis, hyperbilirubinemia and hypoalbuminemia[11]. Patients with comorbidities like cirrhosis, malignancy, liver abscess and coagulopathy also carry poor prognosis.
