The abdominal wall is a very rare site for endometrial cancer metastases. Its appearance generally indicates advanced cancer with poor prognosis. We report a case of a 55-year-old female who presented with an incisional hernia 4 years after abdominal panhysterectomy for endometrioid adenocarcinoma in 2009. Open hernia mesh repair was performed but on follow-up, she complained of pain and a swelling at the repair site. This was radiologically diagnosed as fibromatosis, but tru-cut biopsy confirmed presence of fibromatosis as well as a metastatic endometrial carcinoma...

Pancreatic metastasis from non-small cell lung cancer (NSCLC) is usually asymptomatic or presents with abdominal pain, acute pancreatitis, or jaundice. A lung primary is associated with worse survival compared to pancreatic metastases from other organs. Surgical treatment of solitary metastasis to the pancreas from NSCLC has been reviewed in several studies, one of which had a notable disease-free interval. To our knowledge, there are no prior reports of targeted therapy of pancreatic metastasis of NSCLC followed by a significant response...

BACKGROUND: The treatment of people with acute abdominal pain differs if they have acute pancreatitis. It is important to know the diagnostic accuracy of serum amylase, serum lipase, urinary trypsinogen-2, and urinary amylase for the diagnosis of acute pancreatitis, so that an informed decision can be made as to whether the person with abdominal pain has acute pancreatitis. There is currently no Cochrane review of the diagnostic test accuracy of serum amylase, serum lipase, urinary trypsinogen-2, and urinary amylase for the diagnosis of acute pancreatitis...

BACKGROUND: Alveolar echinococcosis is a potentially lethal zoonosis caused by larval forms of the tapeworm Echinococcus multilocularis. Humans are aberrant intermediate hosts who become infected by ingestion of egg-contaminated food or water or via physical contact with domestic or wild animals that carry the parasite in their small intestine. In humans, the disease usually affects the liver and can spread to other organs causing metastatic infiltration. In this report, we describe an advanced presentation of human alveolar echinococcosis mimicking metastatic malignancy...

BACKGROUND: Incisional hernia is one of the most frequent complications after abdominal surgery, with incidences up to 30%. A reliable biomarker for the prediction of this complication is lacking. Advanced glycosylation end products (AGEs), also known as non-enzymatic collagen crosslinks, are correlated with aging, smoking, hyperglycemia, hyperlipidemia and oxidative stress. In this study the accumulation of AGEs and the relation between AGEs and incisional hernia were investigated. MATERIALS AND METHODS: In an exploratory case-control study, 23 patients with incisional hernia after midline incision were compared with 17 patients without clinical or radiological signs of incisional hernia after midline incision, AGEs were measured using a Skin Auto Fluorescence (SAF)-reader...

Trauma refers to the destruction of tissues or organs by external forces and it is the most common cause of mortality and morbidity in children (1, 2). Injuries of the genitourinary tract may be the result of blunt (falls, sport injuries, motor vehicle accidents and sexual abuse) or penetrating (stab wounds, gun shots, falling onto sharp objects) injuries. The genitourinary tract is significantly injured in 2.9% of paediatric trauma patients 4.In the paediatric population, the kidney is the most affected organ in the genitourinary tract (>60% of all genitourinary tract injuries) 4...

The radiologist's role extends far beyond interpretation and reporting of medical imaging. In this manuscript, we describe the role of the Director of Prostate Imaging. We believe that this model can and should be implemented at other institutions, ultimately serving to improve the care for prostate cancer patients. Moreover, this model can be translated to support the development of an array of patient-centered service lines not only in abdominal imaging, but throughout radiology practices at large.

Giant pheochromocytomas are rare silent entities that do not present with the classical symptoms commonly seen in catecholamine-secreting tumors. In many cases they are accidentally discovered. The algorithm to diagnose a pheochromocytoma consists of biochemical evaluation and imaging of a retroperitoneal mass. The female patient in this case report presented with a palpable abdominal mass and was cured with surgical resection. She suffered no recurrence or complications on follow-up. The left retroperitoneal mass measured 27 × 18 × 12 cm and weighed 3,315 grams...
