Abstract
Pancreatic ductal adenocarcinoma (PDAC) classically presents as a solitary mass on cross-sectional imaging. Diffuse-type PDAC is an unusual variant that accounts for 1%-5% of PDACs. Owing to its rarity, there are no established radiographic or endosonographic definitions. We report a unique case of diffuse-type PDAC presenting with imaging findings of 2 distinct masses in the pancreatic head and tail and with endoscopic ultrasound findings of diffuse gland enlargement mimicking autoimmune pancreatitis. The case illustrates the importance of sampling several areas of the pancreas when diffuse enlargement is present on endoscopic ultrasound and multiple masses are seen on cross-sectional imaging.

Synchronous Pancreatic Ductal Adenocarcinoma in the Head and Tail, a Double Trouble: A Case Report and Literature Review. Diagnostics (Basel) 2022; 12:diagnostics12112709. [PMID: 36359552 PMCID: PMC9689396 DOI: 10.3390/diagnostics12112709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Revised: 10/25/2022] [Accepted: 11/03/2022] [Indexed: 11/09/2022] Open
Abstract
Synchronous primary pancreatic ductal adenocarcinoma (PDAC) is very rare and can be formed either through multicentric carcinogenesis or intrapancreatic metastasis. We report the case of an 80-year-old man with a history of type 2 diabetes mellitus who presented with abdominal pain and weight loss. Laboratory tests showed elevated levels of blood glucose and CA 19-9, and Computed Tomography revealed two hypoenhancing lesions in the head and tail of the pancreas. Endoscopic ultrasound, which is the imaging method of choice for pancreatic cancer, was performed with a fine needle biopsy, and the cytological analysis diagnosed PDAC in both lesions. The patient underwent total pancreatectomy, and pathologic evaluation revealed synchronous primary PDAC with moderate to poor differentiation in the head and tail in the setting of IPMN (intraductal papillary mucinous neoplasia) and chronic pancreatitis. After his recovery from postoperative pulmonary embolism, the patient was discharged home with sufficient glycemic control. Multifocal PDAC occurs more often when precursor lesions, such as IPMN, pre-exist. The optimal treatment for multiple lesions spread all over the pancreas is total pancreatectomy. Diabetes mellitus is a serious complication of total pancreatectomy (new-onset or type 3c), but overall, long-term survival has been significantly improved.

Abstract
Pancreatic ductal adenocarcinomas (PDACs) occasionally have atypical and uncommon imaging presentations that can present a diagnostic dilemma and result in false interpretation. This article aimed to illustrate these CT and MR imaging findings, including isoattenuating PDAC, coexisting acute pancreatitis, PDAC with a cystic feature, groove PDAC, diffuse PDAC, hypointensity on diffusion-weighted imaging (DWI), multifocal PDAC, intratumoral calcification, and extrapancreatic invasion with a barely discernable mass. A subset of PDACs with atypical features are occasionally encountered during routine clinical practice. Knowledge of and attention to these atypical and uncommon variable imaging features may allow radiologists to avoid misinterpretation and a delayed diagnosis.

Abstract
We report a case of a pancreatic ductal adenocarcinoma (PDAC) presenting synchronously with a paraganglioma (PGL) in a Whipple reaction specimen. The patient was a 72-year-old female with a history of breast and vulvar cancer. The simultaneous occurrence of two synchronous tumours in the pancreas was striking. Due to the presence of PGL and multiple meta- and synchronous tumours, the patient was referred to genetic counselling. Tumour tissue from the vulvar carcinoma, the PDAC and the PGL was analysed by targeted next-generation sequencing (NGS) of 161 cancer-related genes and by whole exome sequencing (WES). Peripheral blood was also examined by NGS and WES. These genetic analyses revealed germline polymorphisms in AXIN2 (NM_004655.4:c 0.2272 G>A; p.Ala758Thr), BRCA2 (NM_000059.3:c.9976 A>T; p.Lys3326Ter), NCOR1 (NM_006311.4:c 0.6544 G>A; p.Ala2182Thr) and SPTA1 (NM_003126.3:c 0.373 G>A; p.Ala125Thr) and somatic mutations of KRAS (NM_033360.3;c 0.35 G>A; p.Gly12Asp) and TP53 (NM_000546.5; c.602delT; p.Leu201CysfsTer46) in the PDAC and of TP53 (NM_000546.5; c 0.733 G>A; p.Gly245Ser) and TERT (NM_198253.2; c.-124 C>T; promotor region) in the vulvar carcinoma. Breast carcinoma tissue was not available for genetic analysis. The results of the genetic analyses did not explain the presence of multiple tumours in this patient, despite a slightly increased risk of breast cancer associated with the identified BRCA2 polymorphism. To our knowledge, this is the first report of the synchronous occurrence of PDAC and PGL. This case emphasizes the importance of thorough macroscopic examination of pancreatic resection specimens, as coexisting neoplasms may otherwise be missed.

Abstract
OBJECTIVE To determine the prevalence of multiple solid pancreatic lesions on dynamic enhanced CT performed for suspected pancreatic diseases, and to identify CT features of non-malignancies. METHODS We investigated 8096 consecutive patients who underwent dynamic enhanced CT pancreas protocol at a tertiary center over 40 months. The final clinical /pathological diagnosis served as reference standard. The diagnostic accuracy of dynamic enhanced CT for non-malignancies was calculated. A univariate and multivariate analysis was conducted to identify features that predict non-malignancies. RESULTS Multiple solid pancreatic lesions were identified in 121 patients. The prevalence of non-malignancies was 19.8% (24/121). The most common non-malignancy was autoimmune pancreatitis (n = 21; 17.4%). Common lesions with malignant potential included neuroendocrine neoplasia (n = 62; 51.2%), ductal adenocarcinoma (n = 15; 12.4%), metastasis (n = 9; 7.4%), and lymphoma (n = 7; 5.8%). Dynamic enhanced CT had a sensitivity of 79.2% and a specificity of 92.8% for diagnosing non-malignancies. Elevated serum IgG4 level (p < 0.001), hypo-enhancement in arterial phase (p = 0.001), hyper-enhancement in equilibrium phase (p = 0.009) and location in both proximal and distal pancreas (p = 0.036) were predictors of non-malignancies, whereas pancreatic duct morphology and vascular invasion status were not. CONCLUSION Multiple solid pancreatic lesions were rare, with a wide spectrum. Dynamic enhanced CT provides clues for identifying non-malignancies.

Abstract
Background Only a limited number of multiple synchronous primary malignancies of the pancreas have been reported in the medical literature. We report a case of two solid malignant tumors of the pancreas diagnosed preoperatively. Case presentation We describe a 65-year-old Sri Lankan woman who presented with progressive obstructive jaundice. Initial contrast-enhanced computed tomography imaging detected a malignant tumor at the tail of her pancreas. A second tumor of the pancreatic head was detected with integrated imaging using multidetector computed tomography and multimodal magnetic resonance imaging. She underwent total pancreaticoduodenectomy and splenectomy. Gross examination of the specimen confirmed the presence of two separate tumors. Histology of the ampullary tumor showed pancreatic-type adenocarcinoma and the tumor in the tail of her pancreas showed a colloid-type adenocarcinoma. Conclusion The possibility of multiple primary malignant solid tumors of different types with malignant potential has to be considered even without background pathology when managing multiple tumors in the pancreas.

Endoscopic Ultrasound Fine-Needle Aspiration Diagnosis of Synchronous Primary Pancreatic Adenocarcinoma and Effects on Staging and Resectability. Clin Gastroenterol Hepatol 2017; 15:299-302.e4.

Abstract
Synchronous primary pancreatic adenocarcinoma, defined as the simultaneous presence of 2 or more newly identified and anatomically separate primary adenocarcinomas within the pancreas, is reported rarely. We compared endoscopic ultrasound (EUS) and computed tomography (CT) and magnetic resonance imaging (MRI) findings from patients with synchronous primary pancreatic adenocarcinoma and their effects on cancer staging and treatment. We performed a retrospective analysis of the EUS database at the Mayo Clinic, from September 2008 through May 2016, to collect EUS, CT, MRI, and clinical data from patients with synchronous primary pancreatic adenocarcinoma. EUS and separate fine-needle aspiration of both tumors detected synchronous primary pancreatic adenocarcinoma in 11 patients (70.9 ± 10.4 y; 64% men). Of the 22 cancers, CT (n = 9) and MRI (n = 2) detected 9 (41%) cancers; in only 2 patients did CT detect both cancers. EUS increased cancer stage for 7 of the 11 (64%) patients and changed the status from resectable to unresectable for 3 of the 9 (33%) patients, compared with CT or MRI. EUS findings altered the likely extent of surgical resection for 3 patients. Synchronous primary pancreatic adenocarcinoma is reported rarely and may be undetected by CT or MRI; this could account for the false presumption of early tumor recurrence, rather than actual residual second tumor, leading to incomplete resection.
