Adenoid cystic carcinoma (ACC) is an infrequent cause of malignancy that accounts for 1% of all tumors of the oral and maxillofacial region. We present a 59-year-old woman with a past medical history of adenoid cystic carcinoma of the left salivary gland treated with radiation and thoracotomy due to lung metastasis. Years after the onset of diagnosis, she presented with nonspecific gastrointestinal symptoms. For this reason, an abdominal computed tomography (CT) scan was done, revealing a liver mass in the right lobe, involving segments eight and five, concerning for malignancy...

Lipomas of the digestive tract are rare benign tumours which, in most cases, are totally asymptomatic. Because of their localization within the intestinal wall, endoscopy may be completely negative so contrast-enhanced computed tomography (CT) is very important for detecting and typing these lesions. The case of a 49-year-old man with abdominal pain is presented. Colonoscopy and biopsy of a polypoid lesion on the right colonic flexure concluded for tubulovillous adenoma. The subsequent CT showed a polylobate lesion of 5 cm in diameter with predominant fat density causing luminal sub-stenosis...

INTRODUCTION: Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur. Thus, in the absence of guidelines, further and not always needed diagnostic procedures (colonoscopy, esophagogastroduodenoscopy or capsule endoscopy) are performed...

A 47-year-old female, with multiple comorbidities, presented with a cough of two months, loss of weight and appetite. She was treated for pneumonia. A chest X-ray showed bilateral reticulonodular opacities. She was noted to have a vague central abdominal mass and a systolic murmur over the mitral region. Ultrasonography and computed tomography of the abdomen showed an omental mass and loculated ascites. Oesophagoduedenoscopy showed antral gastritis and during colonoscopy the surgical team was unable to advance the scope beyond 40 cm due to external compression...

INTRODUCTION: Laparoscopic lateral pelvic lymph node dissection (LPLD) is technically challenging because of the complicated anatomy of the pelvic wall. To overcome this difficulty, we introduced preoperative 3-D simulation. The aim of the study is to investigate the usefulness of preoperative 3-D simulation for the safe conduct of laparoscopic LPLD for rectal cancer. METHODS: After undergoing colonoscopy, patients were brought to the radiology suite where multi-detector row CT was performed...

AIM: To evaluate if a single and/or combined (clinical, endoscopic and radiological) assessment could predict clinical outcomes in Crohn's disease (CD). METHODS: We prospectively evaluated 57 CD cases who underwent both a colonoscopy and a CT-enterography (CTE). Harvey-Bradshaw Index (HBi), SES-CD (and/or Rutgeerts score) and the radiological disease activity were defined to stratify patients according to clinical, endoscopic and radiological disease activity respectively...

RATIONALE: Diaphragmatic Hernia is rare as complication of Colonoscopy. Diaphragmatic hernia as a complication of colonoscopy has been reported only few cases. Additionally, it is often misdiagnosed as other disease by clinicians due to their lack of related knowledge, which delays diagnosis of Diaphragmatic hernia and thus exacerbates the prognosis. PATIENT CONCERNS: We report the case of a 66-year-old man with fecal occult blood. In the case, sudden epigastric pain after colonoscopy owing to diaphragmatic hernia in a left hemidiaphragm...

Gastrointestinal angiodysplasia represents the cause of 6% of lower gastrointestinal tract bleeding, particularly in the elderly. Because of the common presentation and age range of affected patients, often patients with occult or massive gastrointestinal bleedings are investigated with colonoscopy, in the suspect of colonic cancer. Other methods are capsule enteroscopy, angiography, double-contrast barium enema, computed tomography angiography, and radionuclide scanning. In this contribution, we describe a case of colonic angiodysplasia first suspected during computed tomography colonography performed after an incomplete colonoscopy in a patient with recent anemization...

BACKGROUND: Carcinoembryonic antigen (CEA) is a glycoprotein, which is present in the foetal colon, some benign conditions and different malignancies, particularly in colon adenocarcinoma. We focused this study on non-melanoma skin cancer (NMSC). NMSC is a common malignancy and it is an important source of morbidity and death in the world. In this study we evaluated whether CEA level increases in NMSC. PATIENTS AND METHODS: A total of 566 patients with non-melanoma skin cancer (NMSC) were enrolled; 286 patients with NMSC showed CEA levels above normal values, and 280 showed CEA levels below normal values...

BACKGROUND: CT colonography is highly sensitive for colorectal cancer, but interval or post-imaging colorectal cancer rates (diagnosis of cancer after initial negative CT colonography) are unknown, as are their underlying causes. We did a systematic review and meta-analysis of post-CT colonography and post-imaging colorectal cancer rates and causes to address this gap in understanding. METHODS: We systematically searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials...

A 16-year-old woman identified with colonic distention using chest X-rays visited our hospital. Although abdominal computed tomography (CT), colonoscopy, and barium enema study indicated suspected duplication of the sigmoid colon, the exact portion of communication between the normal colon and the duplicated colon could not be determined. The patient was released, but followed up due to the lack of symptoms. After 7 months, she was urgently re-hospitalized due to the complaint of abdominal pain. Her abdominal CT revealed the wall thickness and distention of the duplication as well as voluminous stool containing barium...

INTRODUCTION: Pancreatic cancer is the fourth major cause of cancer-related deaths. About 50% of the patients are diagnosed with advanced disease. Metastatic disease to the colon is a very rare entity with only 5 cases described in english literature. CASE PRESENTATION: Male, 60 years-old, presents to a surgical consult with the diagnosis of an adenocarcinoma of the sigmoid colon. The physical exam revealed a periumbilical nodule with suspicious features. The staging CT-scan showed a mass in the tail of the pancreas involving the spleen and left kidney, thickening of the sigmoid colon, multiple mesenteric masses and trabecular changes in the ischium, suggesting metastatic disease...

CT colonography (CTC) has demonstrated equivalent accuracy to optical colonoscopy in the detection of clinically relevant polyps and tumors but this is only possible when technique is optimized. The two most important features of a high-quality CTC are a well-prepared colon and a distended colon. This article will discuss the dietary, bowel preparation, and fecal/fluid tagging options to best prepare the colon. Strategies to optimally distend the colon will also be discussed. CT scan techniques including patient positioning and radiation dose optimization will be reviewed...

An 81-year-old patient with significant cardiac comorbidities, a history of sigmoid resection 6 years ago, and iliac bypass surgery 19 years ago presented with mild hematochezia for the previous 3 days. While hemodynamically stable at first, he developed massive bleeding during preparation for colonoscopy and underwent a short course of cardiopulmonary resuscitation. Colonoscopy revealed no active bleeding but a protuberance of the colonic wall and a coagulation clot. In ultrasonography immediately after endoscopy, a large aneurysm was diagnosed and diagnosis of an iliaco-colonic fistula was assumed...

Systemic lupus erythematosus may rarely present initially with gastroenteric features labelled as lupus enteritis, that may lead to serious complications, if it remains undiagnosed for a long period of time. It is difficult to diagnose because the clinical picture of lupus enteritis mimics gastroenteritis. The diagnosis is made on radiological findings, rather than histopathology, and supported by autoimmune profile. Here is a case of a 40-year lady who presented with diarrhea and vomiting that was unresponsive to treatment with intravenous antibiotics...

A 30-year-old woman was admittedto the hospital because of fecal occult bloodpositivity . Endoscopic colonoscopy indicated pressure on the right side of the rectum from the wall. Abdominal contrast CT and pelvic MRI revealed a cystic lesion with a maximum diameter of 5 cm on the pre-coccyx andthe right side of rectum. There was no continuity between the tumor andthe uterus/ovary. We diagnoseda pararectal tumor andremovedit via a sacral approach. The cyst was diagnosed as an epidermoid cyst. She was discharged on the 5th postoperative day...
