[3] [12] A biopsy of the pancreas is not required for the diagnosis. [3] On imaging, pancreatic and bile duct dilatation, atrophy of the pancreas, multiple calcifications of the pancreas, and enlargement of pancreatic glands can be found. [12] On MRI scan, there is a low T1 signal due to inflammation, fibrosis, focal lesions, and calcifications.
It is usually solitary and found in the body or tail of the pancreas, and may be associated with von Hippel–Lindau syndrome. [2] In contrast to some of the other cyst-forming tumors of the pancreas (such as the intraductal papillary mucinous neoplasm and the pancreatic mucinous cystadenoma), serous cystic neoplasms are almost always entirely ...
Sclerosing polycystic adenosis (also abbreviated SPA) is a rare salivary gland tumor first described in 1996 by Dr. Brion Smith. [1] The major salivary glands, specifically the parotid gland (about 70% of cases) and the submandibular gland , are affected most commonly.
Chronic sclerosing sialadenitis is a chronic (long-lasting) inflammatory condition affecting the salivary gland. Relatively rare in occurrence, this condition is benign, but presents as hard, indurated and enlarged masses that are clinically indistinguishable from salivary gland neoplasms or tumors.
Autoimmune Pancreatitis; Other names: AIP: A. Axial CT image in the pancreatic parenchymal phase shows the typical enlarged, poorly enhancing gland. B. Coronal T2 Weighted MR image demonstrates low signal intensity in the pancreas due to the diffuse fibrosis in the gland.
Sclerosing polycystic sialadenitis histologically resembles sclerosing adenosis/fibrocystic change of breast tissue. It composes of acini and ductal elements embedded in dense sclerotic stroma, and has a characteristic finding of large acinar cells present with abundant eosinophilic cytoplasmic granules.
Cystic lesions of the pancreas are a group of pancreatic lesions characterized by a cystic appearance. They can be benign or malignant. [citation needed] Cystic lesions are found in 20.6% of all pancreatectomy specimens.
Salivary gland tumours, or neoplasms, are tumours that form in the tissues of salivary glands.The salivary glands are classified as major or minor.The major salivary glands consist of the parotid, submandibular, and sublingual glands.
