Serous cystadenoma of the pancreas is a type of pancreatic cystic neoplasm frequently found in clinical practice. Serous cystadenoma of the pancreas can have a varied morphological presentation on imaging examinations. Therefore, it is sometimes very challenging to differentiate serous cystadenoma of the pancreas from pancreatic malignancy. In this study, we present a case of serous cystadenoma of the pancreas showing focally elevated radiotracer uptake on 68 Ga-FAPI PET/CT. Considering potential future clinical use of 68 Ga-FAPI PET/CT in malignancy, awareness of the false-positive findings is important for the differential diagnosis and management of these lesions.

Serous cystadenoma (SCA) of the pancreas is a benign nonmucinous cystic pancreatic neoplasm and the second most common type of pancreatic cystic neoplasm. Conservative management is advocated in asymptomatic cases as they have indolent clinical behavior and risk for postoperative morbidity, making an exact diagnosis essential. Morphologically, serous cystadenoma has a prominent subepithelial capillary meshwork causing the aspirate to be paucicellular and nondiagnostic.

Objectives: To improve preoperative diagnostic accuracy of struma ovarii by retrospectively reviewing magnetic resonance (MR) findings. It is beneficial to choose the most appropriate surgical modality for the patient.
Methods: We retrospectively reviewed the clinical course and MR characteristics of 52 patients who were diagnosed postoperatively with struma ovarii, pathologically, from two institutions.

An asymptomatic 79-year old woman presented with a 40 mm pancreatic cystic lesion, located in the pancreatic body-tail and consistent with branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) without "high risk stigmata". During a 4-year follow-up period, imaging showed no mural nodules or main pancreatic duct dilation, and serum CEA and CA19.9 were within normal range.

Background: Müllerian cysts of the posterior mediastinum are rare, benign lesions typically discovered incidentally via routine medical exams.
Case Presentation: We present a distinctive case of a 49-year-old asymptomatic woman, illustrating a rare Müllerian cyst located in the posterior mediastinum with serous papillary cystadenoma-like features, a novel finding in the medical literature. Identified during a routine health screening in December 2020, a 20 mm cystic lesion adjacent to the T4-5 vertebral body was detected through chest CT and MRI, initially suggesting a neurogenic tumor.

Whereas pancreatic masses are often difficult to detect with transabdominal ultrasound, cross-sectional imaging features high sensitivity for the pancreatic tumors. However, increasing availability of magnetic resonance imaging (MRI) has led to a surge in the detection of benign or precancerous pancreatic lesions. The medical history is characteristic only for two entities.
