Abstract
RATIONALE
Mucinous cystic neoplasms (MCNs) are pancreatic mucin-producing cystic lesions with a distinctive ovarian-type stroma. The diagnosis is generally easy in typical cases; however, differential diagnosis is difficult in others such as in the case we report herein.
PATIENT CONCERNS
A 27-year-old woman with sudden onset of epigastric pain was referred to our hospital for suspected acute pancreatitis. Contrast-enhanced computed tomography revealed a 25-mm cystic lesion in the pancreas and a low density area with delayed enhancement at the right upper side of the cystic lesion.
DIAGNOSES
During its clinical course, the cystic lesion underwent various morphological changes. Eventually, it presented typical findings of MCNs, and could be accurately diagnosed.
INTERVENTIONS
Laparoscopic distal pancreatectomy was performed on the patient by preserving the spleen.
OUTCOMES
The patient revealed no symptoms till 1 year after the operation.
LESSONS
This case of MCN with intriguing short-term morphological changes was associated with recurrent pancreatitis. A combination of imaging modalities is essential for accurate diagnosis of MCNs, and follow-up with serial imaging might be useful for certain unusual lesions.
