We report a colonic adenocarcinoma associated with diffuse submucosal deposition of a peculiar spheroid-type amyloid identified in the colon, terminal ileum, and appendix. A 65-year-old woman with past medical histories of hypertension, and chronic obstructive pulmonary disease, presented to the emergency room with cramping abdominal pain and nausea. A computed tomography (CT) scan of abdomen showed right colonic volvulus. Emergency right hemicolectomy was performed. The specimen showed colonic adenocarcinoma with focal submucosal invasion (pT1) arising from a villotubular adenoma...

An 84-year-old man with multiple comorbidities presented from a residential care home with a 1-month history of asthenia and moderate abdominal pain. On examination, he was found to have an irreducible right-sided inguinoscrotal hernia. Subsequent blood tests revealed a significant anaemia (haemoglobin 48 g/L), for which he was transfused. A CT scan of the abdomen and pelvis revealed a large caecal tumour, herniating through the right inguinal canal into the scrotum. The patient underwent an elective open right hemicolectomy with inguinal hernia defect repair, from which he recovered well...

INTRODUCTION: Fatty liver disease (FLD) is correlated with cardiovascular disease. Carotid intima-media thickness (CIMT) and coronary artery calcium score (CACS) can noninvasively identify subclinical atherosclerosis and predict risk for cardiovascular events. This study evaluated CIMT and CACS measurements to detect subclinical atherosclerosis in patients with and without FLD. METHODS: Patients who underwent carotid and abdominal ultrasounds as well as cardiac computed tomography (CT) scans were evaluated retrospectively...

BACKGROUND AND OBJECTIVE: There is evidence of association between aging and increase in the normal upper limit of the common bile duct (CBD) diameter. As aging is a documented risk factor for atherosclerosis, and the possible effect that atherosclerosis can have on the CBD diameter via affecting its smooth muscle contractility and blood flow, we decided to determine the association between CBD diameter and atherosclerosis in the abdominal aorta (AA). METHODS: A total of 99 asymptomatic patients (53 males and 46 females; age range of 18-88 years) without history of cholecystectomy who underwent abdominal contrast-enhanced CT scan were included...

Median arcuate ligament (MAL) syndrome is a rare and poorly known cause of abdominal pain. MAL narrows the celiac artery (CA), resulting in true distal aneurysms, including pancreaticoduodenal artery (PDA) aneurysms. These aneurysms often have an aggressive course, as rupture can result in hemorrhagic shock. CT scan appears to be the most effective investigation for the diagnosis of PDA aneurysms and may reveal possible celiac artery compression. In this series, we describe four cases of PDA aneurysm: two ruptured aneurysms treated by an endovascular procedure and two non-ruptured aneurysms treated by surgery...

Diffuse Large B-Cell Lymphoma (DLBCL) is the most common histological subtype of Non-Hodgkin's Lymphoma (NHL). Primary retroperitoneal DLBCL is uncommon and has seldom been reported. Extrinsic compression of the duodenum due to lesions originating from the retroperitoneum is also rare. We present a case of a 39-year-old man who presented with inability to tolerate oral intake, abdominal pain, an upper abdominal mass and postprandial bilious vomiting caused by a large DLBCL arising from the retroperitoneum causing extrinsic compression of the duodenum...

INTRODUCTION: Radiotherapy outcomes are influenced by treatment delivery geometric accuracy and organ-at-risk dose. The location of abdominal structures such as the liver, kidneys and tumour volumes can be strongly influenced by respiratory motion. This increases geometric uncertainty and dose to organs-at-risk. One common method of minimising respiratory motion is abdominal compression (AC). METHODS: Fifteen patients being treated for radiotherapy to upper abdominal tumours were analysed...
