Pancreatic Cystic Neoplasms: Diagnostic Challenges and Management Pathways Through Case-based Insights

Mucinous cystic neoplasms (MCNs) are rare pancreatic lesions that often go undiagnosed due to their asymptomatic nature. Though typically benign, they can harbor malignant potential, making early detection and treatment essential. This case report presents a 32-year-old female with intermittent epigastric pain, who was found to have a cystic lesion in the pancreatic tail, diagnosed as an MCN through endoscopic ultrasound and fine-needle aspiration. The patient underwent a spleen-sparing distal pancreatectomy, which was complicated by a peri-pancreatic abscess that required drainage. This case highlights the importance of distinguishing MCNs from other pancreatic cystic lesions, as misdiagnosis or delayed intervention can lead to adverse outcomes. It underscores the need for vigilant diagnostic imaging and individualized treatment strategies, particularly in young patients, to avoid unnecessary morbidity and ensure optimal outcomes. The report contributes to the growing understanding of MCNs, emphasizing early diagnosis, tailored surgical management, and the significance of postoperative care.
