CT colonoscopy

Christoph Kloth, Konstantin Nikolaou, Stephan Clasen
History and clinical findings: We present the case of a 63-year-old male patient free of complaints with oncological follow up examination after renal cell carcinoma (RCC) who presented extent air in the intestinal wall. Investigations and diagnosis: The computed tomography showed a pronounced pneumatosis intestinalis with punctum maximum in the part of left and less right colon flexure. Free air as a sign of perforation was not found. Treatment and course: Retrospectively, the pneumatosis intestinalis was found in fluctuating extent in several preliminary CT and MRI investigations...

We herein experienced a case with pseudo-Meigs' syndrome that developed both synchronous and metachronous metastases to the ovary from ascending colon cancer. A 57-year-old female visited a hospital for a 2-month history of abdominal distension and voiding difficulty. Massive pleural effusion on the right side and a small amount of left-sided pleural effusion were detected on CT. She underwent emergent laparotomy due to the severe symptom of abdominal distention. The tumor originated from the left ovary, and left-sided oophorectomy was performed...

Pneumatosis cystoides intestinalis (PCI) is an uncommon disease that generally lacks symptoms and is rarely associated with intussusception. A 29-year-old man visited our hospital for right upper abdominal pain. Computed tomography (CT) scan revealed multiple air-filled cysts along the intestinal wall and a pseudokidney sign in the transverse colon. A gastrographin enema examination showed a so-called crab finger appearance and multiple elevated translucency in the transverse colon. From these findings, the diagnosis of intussusception associated with PCI was made...

BACKGROUND: Perforation of the colon occurring during or shortly following colonoscopy or barium enema is a rare complication of collagenous colitis (CC). "Spontaneous" perforation in CC, in which no instigating factor is identified, is even less common, with only five cases reported to date. We report herein an additional case of spontaneous perforation in previously undiagnosed CC and review the clinical and pathological features of previously reported cases. CASE PRESENTATION: An 80 year old woman presented to the emergency department with abdominal pain preceded by approximately one month of frequent non-bloody diarrhea...

We report the case of a 53-year-old female patient who was transplanted with the liver of a 71-year-old male donor for advanced primary sclerosing cholangitis (PSC) and who additionally was diagnosed with a histologically non-classifiable colitis shortly before transplantation. Upon follow-up abdominal ultrasound 4 months after transplantation, a liver lesion measuring 16 × 23 mm was detected in the transplanted liver. This lesion had not been noticed immediately after transplantation and showed a pattern suspicious for malignancy in contrast-enhanced ultrasound...

Burkitt's lymphoma is a very aggressive type of B-cell NHL with replication approaching 100%. Primary gastrointestinal lymphoma is rare. In our case, a 24-year-old male initially presented with symptomatic anemia. He was initially evaluated with colonoscopy and EGD, both of which were unremarkable. A capsule endoscopy was then performed to further evaluate his significant anemia which revealed friable inflamed ulcerated mass in the jejunum. A push enteroscopy was then performed to obtain tissue from the jejunal mass...

PURPOSE: We evaluated all PET/CTs acquired for patients without a primary diagnosis of colorectal cancer, and compared results for those who had subsequent colonoscopy within 6 months, to assess the accuracy of FDG PET/CT for detection of incidental pre-malignant polyps and malignant colon cancers. MATERIALS AND METHODS: Medical records of 9,545 patients who underwent F-18 FDG PET/CT studies over 3.5 years were retrospectively reviewed. Due to pre-existing diagnosis of colorectal cancer, 818 patients were excluded...

We describe a rare case of an 81-year-old man who presented with severe epigastralgia. A chest radiograph showed massive free gas bilaterally in the diaphragmatic spaces. Computed tomography (CT) scan also showed massive free gas in the peritoneal cavity with portal venous gas. We used a wait-and-see approach and carefully considered surgery again when the time was appropriate. The patient received conservative therapy with fasting, an intravenous infusion of antibiotics, and nasogastric intubation. The patient soon recovered and was able to start eating meals 4 d after treatment; thus, surgical intervention was avoided...

BACKGROUND: We experience many cases of liver metastasis from colorectal cancer, but synchronous occurrence of intrahepatic cholangiocarcinoma (ICC) and liver metastasis from a rectal cancer is extremely rare. We herein report a case of ICC coinciding with a liver metastasis from a known rectal carcinoma. CASE PRESENTATION: A 68-year-old man was referred to our hospital for investigation of multiple liver tumors. Total colonoscopy and computed tomography (CT) revealed a rectal carcinoma, coinciding with liver metastasis...

CONTEXT: The vasoactive intestinal peptide-secreting neuroendocrine tumor (VIPoma) is a very rare pancreatic tumor. We report the first case of a patient with VIPoma that co-secreted dopamine and had pulmonary emboli. CASE DESCRIPTION: A 67-year-old woman presented with 2 months of watery diarrhea, severe generalized weakness,6.8 kg of weight loss, a facial rash, and hypokalemia. Colonoscopy did not reveal the cause of the chronic diarrhea. Initial biochemical testing showed markedly elevated serum vasoactive intestinal peptide (VIP) and pancreatic polypeptide...

BACKGROUND: Positron emission tomography/computed tomography (PET/CT) is an important modality in cancer imaging. With its increasing availability and use, it is not uncommon to detect incidental focal colorectal (18) F-FDG uptake which poses a diagnostic challenge, as they may be associated with malignant or pre-malignant colorectal lesions. The aim of our study is to determine the proportion of these findings which represents true pathology. METHODS: Patients with incidental focal colorectal (18) F-FDG uptake on PET/CT who subsequently underwent colonoscopy between January 2002 to September 2013 were identified from a prospective database in a tertiary referral centre...

INTRODUCTION An understanding of the volume of incoming referrals to a colorectal cancer (CRC) service is essential for adequate delivery of service. We hypothesised that the number of 2-week-wait (2WW) referrals has increased over recent years, with a concomitant increase in demand for endoscopic and imaging investigations. METHODS A retrospective review of all referrals from primary care with suspected malignancy to Barking, Havering and Redbridge NHS Trust (BHRNHST, London, UK) from 2009 to 2014 was undertaken...

The existing recommendations for fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) use in digestive cancers (excluding neuroendocrine tumours) are summarized in the present article. FDG-PET/CT is nowadays a routine imaging modality for digestive malignancies and its use is currently increasing. FDG-PET/CT is considered to be a crucial tool in pretherapeutic assessment of esophageal, localized pancreatic and anal cancer. It represents a key exam in suspicion of recurrence of colorectal cancer in case of elevated serum tumor markers...

CT colonography (CTC) is a minimally invasive radiological investigation of the colon. Robust evidence indicates that CTC is safe, well tolerated and highly accurate for the detection of colorectal cancer (CRC) and large polyps, which are the targets of screening. Randomised controlled trials were carried out in Europe to evaluate CTC as primary test for population screening of CRC in comparison with faecal immunochemical test (FIT), sigmoidoscopy and colonoscopy. Main outcomes were participation rate and detection rate...
