Acute cholangitis is a critical medical condition requiring prompt intervention. This case report explores the complexities and uncertainties encountered in clinical decision-making when faced with a patient presenting with symptoms suggestive of acute cholangitis. We emphasise the importance of considering individual circumstances and factors in the diagnostic process. A 38-year-old woman with a history of Crohn's colitis presented with abdominal pain, jaundice and leukocytosis. Initial evaluation raised suspicions of acute cholangitis, but unexpected findings of blast cells in the peripheral smear led to a diagnosis of B-lymphoblastic leukaemia with BCR-ABL1 fusion. Treatment with steroids and chemotherapy resulted in the resolution of liver abnormalities. This case underscores the necessity of comprehensive assessments for obstructive jaundice and highlights the potential diagnostic challenges posed by underlying haematologic malignancies. It also raises awareness about drug-induced liver injury, and emphasises the importance of complete blood counts and differentials in the initial workup. Healthcare providers should be vigilant in considering alternative diagnoses when faced with obstructive jaundice, as misdiagnosis can lead to invasive procedures with potential adverse events.
Learning points: This case highlights the significance of conducting a thorough initial assessment when a patient presents with symptoms suggestive of liver involvement, such as abdominal pain, jaundice and leukocytosis. In this case, the patient's initial symptoms were initially attributed to potential cholangitis due to her clinical presentation, but a peripheral smear unexpectedly revealed blast cells, leading to a diagnosis of B-lymphoblastic leukaemia.The case demonstrates that haematologic malignancies can manifest with various patterns of hepatic involvement, and their presentation can be diverse. In this instance, obstructive jaundice was caused by leukaemic infiltration of the liver, which is a rare initial presentation of acute lymphoblastic leukaemia (ALL).This demonstrates the diagnostic challenges in identifying rare conditions such as leukaemic infiltration of the liver, emphasising the importance of appropriate investigations and consultation with specialists.
