Abstract

Pancreatic exocrine carcinoma (PEC) is a lethal malignancy with high mortality rates because of its aggressive nature and frequent late-stage diagnosis. When histopathological diagnosis becomes unfeasible because of patient deterioration, clinicians must rely on clinical, biochemical, and radiological findings. This case report describes a 78-year-old woman with aggressive PEC visualized through ¹⁸F-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT). The imaging revealed an intensely hypermetabolic head mass, hepatic superscan, and hypermetabolic abdominal lymphadenopathy. Despite strong clinical indicators suggesting stage IV PEC, rapid disease progression and patient demise precluded histopathological confirmation, emphasizing the poor prognosis associated with hepatic superscan in this context.
