Abstract
We here report a case of pancreatic duct rupture associated with high-grade pancreatic intraepithelial neoplasia treated by radical resection. A 71-year-old man presented to our hospital because of abdominal bloating. Diagnoses of early-stage pancreatic body cancer with pancreatic duct rupture, pancreatic ascites, and formation of a pseudocyst were made on the basis of blood tests, multidetector dynamic computed tomography, endoscopic ultrasonography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography. After achieving control of the ascites by placement of a pancreatic duct stent and aspiration of the pseudocyst, distal pancreatectomy with D2 lymph node dissection was performed. Intraoperative cytologic examination of the ascites was negative. The pathological diagnosis was high-grade pancreatic intraepithelial neoplasia in the pancreatic body. The branched pancreatic duct was occluded and dilated by acute inflammation around the pancreatic neoplasm, the inflammation being in the region of the dilated branched pancreatic duct and having caused its rupture. To the best of our knowledge, this is the first published report of pancreatic duct rupture associated with high-grade pancreatic intraepithelial neoplasia.

Needle tract seeding and abscess associated with pancreatic fistula after endoscopic ultrasound-guided fine-needle aspiration. Clin J Gastroenterol 2020; 13:1322-1330. [PMID: 32720220 DOI: 10.1007/s12328-020-01188-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Accepted: 07/17/2020] [Indexed: 02/07/2023]
Abstract
We present the first report of needle tract seeding with simultaneous abscess associated with pancreatic fistula occurring after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic ductal adenocarcinoma (PDA). A 72-year-old woman complained of fever 18 days after EUS-FNA for PDA of the pancreatic tail with a retention cyst. An abscess associated with pancreatic fistula containing necrotic debris formed in the EUS-FNA needle tract was successfully treated with endoscopic drainage and antibiotics. Distal pancreatectomy with partial gastrectomy was performed after neoadjuvant chemotherapy. Complete resection was achieved but peritoneal lavage cytology was positive for cancer. Pathology of the resected specimen revealed cancer cells invading the gastric submucosa at the EUS-FNA puncture site from the serosal side. The lining of the retention cyst was free of cancer cells. Liver metastases and peritoneal carcinomatosis were seen 3 months after surgery. While needle tract seeding has recently received attention as a complication of EUS-FNA, endoscopists should also be alerted to the possibility of abscess associated with pancreatic fistula after EUS-FNA for PDA.

The usefulness of (18)F-FDG PET/MRI fusion image in diagnosing pancreatic tumor: comparison with (18)F-FDG PET/CT. Ann Nucl Med 2013; 27:554-63. [PMID: 23580090 DOI: 10.1007/s12149-013-0719-3] [Citation(s) in RCA: 55] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2012] [Accepted: 03/17/2013] [Indexed: 12/17/2022]
Abstract
PURPOSE This study aimed at demonstrating the feasibility of retrospectively fused (18)F FDG-PET and MRI (PET/MRI fusion image) in diagnosing pancreatic tumor, in particular differentiating malignant tumor from benign lesions. In addition, we evaluated additional findings characterizing pancreatic lesions by FDG-PET/MRI fusion image. METHODS We analyzed retrospectively 119 patients: 96 cancers and 23 benign lesions. FDG-PET/MRI fusion images (PET/T1 WI or PET/T2WI) were made by dedicated software using 1.5 Tesla (T) MRI image and FDG-PET images. These images were interpreted by two well-trained radiologists without knowledge of clinical information and compared with FDG-PET/CT images. We compared the differential diagnostic capability between PET/CT and FDG-PET/MRI fusion image. In addition, we evaluated additional findings such as tumor structure and tumor invasion. RESULTS FDG-PET/MRI fusion image significantly improved accuracy compared with that of PET/CT (96.6 vs. 86.6 %). As additional finding, dilatation of main pancreatic duct was noted in 65.9 % of solid types and in 22.6 % of cystic types, on PET/MRI-T2 fusion image. Similarly, encasement of adjacent vessels was noted in 43.1 % of solid types and in 6.5 % of cystic types. Particularly in cystic types, intra-tumor structures such as mural nodule (35.4 %) or intra-cystic septum (74.2 %) were detected additionally. Besides, PET/MRI-T2 fusion image could detect extra benign cystic lesions (9.1 % in solid type and 9.7 % in cystic type) that were not noted by PET/CT. CONCLUSIONS In diagnosing pancreatic lesions, FDG-PET/MRI fusion image was useful in differentiating pancreatic cancer from benign lesions. Furthermore, it was helpful in evaluating relationship between lesions and surrounding tissues as well as in detecting extra benign cysts.
