Unlabelled: Imaging appearance of cyst-like changes is most frequently described in primary neuroendocrine lesions, especially pancreatic NETs.The imaging finding of a pseudocystic lesion of the liver puts in differential diagnosis many pathologies such as infectious diseases, simple biliary cysts up to biliary cystadenomas and eventually to primary or metastatic malignancies.Primary or metastatic hepatic malignancies with pseudocystic aspects are rare, and a pseudocystic aspect is reported only after neo-adjuvant treatment.Liver metastasis of untreated neuroendocrine tumors are usually solid and, to our knowledge, only two cases of neuroendocrine cystic hepatic metastases of ileal atypical carcinoids have been reported so far.We present a case of a 67 years old man with synchronous finding of an untreated hepatic pseudocystic lesion and an ileal mass histologically diagnosed as a well differentiated (G1) neuroendocrine tumor.

The relationship between spontaneous cystic degeneration and pseudocapillarization in sinusoids in the liver of aged Sprague-Dawley rats.

Cystic degeneration (CD) in the liver is a cyst-like lesion composed of one or more pseudocysts lacking lining cells, occurring spontaneously in rats older than 12 months, with a male predilection. In this study, 32 CDs were identified in 23 out of 104 non-treated, control male Sprague-Dawley rats from two combined chronic toxicity and carcinogenicity studies with agrochemicals. They were examined histologically, histochemically, and immunohistochemically to assess the pathogenesis and pathological significance of CD, focusing on pseudocapillarization in aged rat liver.

Hemosuccus pancreaticus (HP) is characterized by gastrointestinal bleeding from the papilla of Vater via the pancreatic duct. In this report, we describe a case of HP due to arterial perforation in a pancreatic pseudocyst and discuss the computed tomography (CT) findings and efficacy of stent graft placement. A 64-year-old man with a history of heavy alcohol use, situs inversus totalis, and total gastrectomy was hospitalized with hematochezia.

Hepatic artery pseudoaneurysm (HAP) is an uncommon yet critical complication of acute pancreatitis. This case delves into the unusual scenario of a two-month-old male infant with a familial history of pancreatitis who develops the condition himself. Despite initial treatment, the infant's symptoms worsened, unveiling a pancreatic pseudocyst (PCC) and an atypical pseudoaneurysm stemming from the hepatic artery, a rare complication in acute pancreatitis.

Objectives: To describe the MR features and prognosis of patients with an uncommon complication of primary sclerosing cholangitis (PSC) characterized by a spontaneous perforation of the common bile duct (CBD) resulting in a peri-biliary collection and a pseudo-cystic appearance of the CBD.
Methods: A single-center cohort of 263 patients with PSC who had at least two MRIs between 2003 and 2022 and a minimum follow-up of 1 year was retrospectively analyzed. MRI data (characteristics of CBD perforation and MR features of PSC) and clinical data were assessed.

Objective: We aimed to analyze the clinical presentation, imaging, histopathology, and surgical management of pediatric intraabdominal cysts, which are relatively common but diverse lesions that pose diagnostic challenges.
Materials And Methods: We conducted a retrospective analysis of pediatric intraabdominal cysts from 2010 to 2021 in a single tertiary center. We collected data on demographics, symptoms, radiological findings, surgical approaches, and histopathological diagnoses and compared them with the current literature.
