The prevalence of accessory ossicles and sesamoids is widely variable.[1,4,5] These bones are normal variants and remain asymptomatic, usually overlooked or misdiagnosed.[1,6] These ossicles and sesamoids are involved in various diseases, including fractures, dislocations, degenerative changes. Others include osteonecrosis, osteoarthritis, osteochondral lesion, avascular necrosis, and impingement syndromes.
Solid pseudo-papillary epithelial neoplasm (SPEN), also known Hamoudi tumors or Franz tumors, are rare pancreatic neoplasm which are almost always seen in young women predominately of non-Caucasian descent with only a small minority of cases diagnosed in men [1]. The first published description of an SPN was by Frantz in 1959[2]. . It is a rare tumor comprising of less than 3 percent of all pancreatic tumor. It is seen most often in the region of tail of pancreas. This tumor is mostly asymptomatic and usually detected when it reaches large size. These are tumors with low malignant potential and rarely vascular invasion and metastatic disease can be seen in aggressive cases. Here we report two cases, one each of benign SPEN and malignant SPEN with contrasting imaging findings and polar outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
