Agenesis of Abdominal Organs: A Radiological Case Series

Abstract

 Aim of Study: To evaluate the radiological findings, clinical presentations, and compensatory mechanisms associated with congenital anomalies such as left liver lobe agenesis, dorsal pancreatic agenesis, gallbladder agenesis, and duplex collecting system with ectopic ureter insertion in adult patients. Introduction: Congenital anomalies of the liver, pancreas, and gallbladder are rare but clinically significant due to their variable presentations and impact on organ function. These anomalies are often undetected until adulthood and typically discovered incidentally during radiological evaluations. Case Descriptions: Case 1: A 35-year-old female with urinary incontinence was referred for radiological evaluation and had no significant medical history. Case 2: A 45-year-old female with recurrent diffuse abdominal pain for one year sought consultation. She had occasional abdominal discomfort but no other systemic symptoms. Case 3: A 40-year-old female with right upper quadrant pain, dyspepsia, and bloating presented with no prior surgeries, incisional scars, or family history of congenital anomalies. Physical examination revealed no jaundice or pallor. The patient exhibited mild tenderness in the right hypochondrium without any signs of guarding. Laboratory investigations, including liver function tests, were normal. Clinical Significance: This report highlights the clinical importance of recognizing rare congenital anomalies like left liver lobe agenesis, dorsal pancreatic agenesis, and gallbladder agenesis, which can mimic common conditions and complicate diagnosis. These anomalies, often detected incidentally, require careful imaging interpretation (CT, ultrasound) to avoid misdiagnosis and unnecessary procedures. Early detection and accurate imaging improve diagnosis and patient care. Conclusion: Advanced imaging techniques are essential for accurate diagnosis and management, aiding in differentiating congenital agenesis from other pathologies and understanding compen satory organ adaptations.
