Rare pancreatic masses: a pictorial review of radiological concepts.

Non-ductal pancreatic neoplasm (NPN) represents a heterogeneous group of pancreatic masses, in which diagnosis and management remain challenging due to their overall rarity. Knowledge of their radiologic features is essential for differential diagnosis and to guide clinical decisions for optimal management. The purpose of this paper was to present radiological patterns of these rare pancreatic tumors, solid or predominantly solid, with emphasis in the differential diagnosis and surgical management.

Paracoccidioidomycosis in a liver transplant recipient.

Paracoccidioidomycosis is a granulomatous systemic mycosis that is endemic in Latin America; it is an extremely rare infection following solid organ transplantation. In this study, we describe the first report of disseminated paracoccidioidomycosis in a 3-year-old girl who underwent liver transplantation 2 years previously. The radiologic diagnosis and patient follow-up are described.

Synchronous resection of pancreatic serous cystadenocarcinoma and liver metastasis: First reported case and review of literature.

Cystic neoplasms account for approximately 10-20% of all pancreatic cysts and 1% of pancreatic cancers. Serous cystadenomas are considered benign tumors with almost no malignant potential, and thus the management is typically only observation with serial imaging. According to the current World Health Organization classification, cases with distant metastases are defined as serous cystadenocarcinomas.

Spontaneous combined rupture of a pelvicalyceal cyst into the collector system and retroperitoneal space during the acquisition of computed tomography scan images: a case report.

Introduction: Pelvicalyceal cysts are common findings in autopsies and can manifest with a variety of patterns. These cystic lesions are usually a benign entity with no clinical significance unless they enlarge enough to cause compression of the adjacent collecting system and consequently obstructive uropathy. Few cases of the spontaneous rupture of pelvicalyceal renal cysts have been published and to the best of our knowledge there is no report of a combined rupture to collector system and retroperitoneal space documented during a multiphase computed tomography.
