Cinematic rendering: a new imaging approach for ulcerative colitis

AbstractPurposeCinematic rendering (CR) is a new technique for visualizing volumetric three-dimensional data. The purpose of this study was to investigate the added value of CR to conventional computed tomography (CT) in the diagnosis and evaluation of ulcerative colitis (UC).Materials and methodsWe retrospectively evaluated the CT data of 48 patients (33 men, 15 women; mean age, 44.35  years) with a definitive diagnosis of UC. All patients underwent conventional CT and CR, and had colonoscopy results. Two radiologists independently reviewed the conventional CT images first without and then with CR. Then, the imaging value of CR was evaluated by both radiologists together. The re aders were blinded to the disease extent. The diagnostic performance of CR for both readers was assessed by receiver-operating characteristic (ROC) curve analysis.ResultsThere were 23 cases of mild to moderate UC and 25 cases of severe UC, which were divided into two groups. Both readers showed improved diagnostic performance with the addition of CR (the area under the ROC curve improved from 0.676 to 0.804,P = 0.0255, and from 0.679 to 0.826,P = 0.0049, for readers 1 and 2, respectively). Full view of the lesion and contrast enhancement was not significantly different between the two groups (P >  0.05). Increased mesenteric vascularity and the comb sign on CR were more clearly observed in the severe group (P

We present an indolent pancolonic MALT lymphoma occurring in a 39-year-old female with history of autoimmune hepatitis requiring liver transplant in 1997 and ulcerative colitis diagnosed in 2004. Random biopsies from a grossly unremarkable surveillance colonoscopy in 2015 revealed a dense monomorphic plasmacytoid infiltrate causing expansion of lamina propria without significant crypt infiltration or destruction. These cells were positive for CD79a and CD138 and showed lambda restriction; however, CD20, CD43, CD56, HHV8, and EBER were negative. A similar pancolonic infiltrate was identified in all prior colorectal biopsies...

Multifocal Colonic Wall Abscesses during Anti-Tumor Necrosis Factor (TNF)-α Therapy for a Patient with Ulcerative Colitis: A Very Rare Manifestation of Infectious Complications. Intern Med. 2017;56(10):1157-1161 Authors: Fukui T, Takahashi M, Okazaki T, Tomiyama T, Fukata N, Ando Y, Okazaki K Abstract A 24-year-old woman was transferred to our hospital under suspicion of an exacerbation of her known ulcerative colitis. Colonoscopy revealed an edematous swelling and multifocal discharge of pus throughout the descending colon, concurrent with active ulcerative colitis findings in the rectum and sig...

We present the case of a 63-year-old man with a LAMN type 1 lesion, diagnosed at routine colonoscopy for surveillance of ulcerative colitis. Because in earlier surveillance colonoscopies, this lesion was misinterpreted as fecal polution, for the first time, this case describes retrospectively a 3-year endoscopic follow-up of LAMN type 1, underlining the benign course of these kind of lesions compared to type 2 lesions with submucosal infiltration. Even though endoscopy and sonography are not accepted as method of choice to detect LAMN lesions, our case highlights their role regarding diagnosis of small lesions, as CT scan ...

We report a case of colitis-associated rectal cancer (CARC) accompanied by intrahepatic cholangiocarcinoma (ICC) based on UC and PSC. A 73-year-old man had suffered from UC for 19 years. During surveillance colonoscopy, a tumor was found in the rectum that was pathologically diagnosed as CARC from the resected specimen. Abdominal computed tomography also revealed a localized dilation of the intrahepatic bile duct, and endoscopic retrograde cholangiography revealed a band-like stricture. This remarkable tumor lesion was not observed in the hepatic duct. Left hepatectomy was performed because of the suspicion of possibl...

Authors: Mirioglu S, Cavus B, Iliaz R, Besisik F Abstract A 70-year-old man was admitted to our clinic with a history of rectal bleeding and constipation, his colonoscopy revealed varicosities and bluish nodular lesions of the rectum (Figure 1). Abdominal CT showed multiple nodular lesions beginning from the distal descending colon and extending to the rectum, calcifications suggesting phleboliths were also seen in these lesions. A contrast enhanced pelvic MRI demonstrated multiple tubular lesions showing hyperintensity on T2-weighted images and hypointensity on T1-weighted images, consistent with the affected area...

Background: The inflammatory burden influences therapeutic decisions in patients with ulcerative colitis (UC). We aimed to study which commonly used markers of disease activity correlate best with inflammatory burden in patients with UC using leukocyte scintigraphy (single-photon emission computed tomography [SPECT-CT]) as the gold standard. Methods: Patients with different severity of UC underwent colonoscopy with biopsies and leukocyte SPECT-CT scintigraphy. Serum C-reactive protein (CRP), fecal calprotectin, and clinical questionnaires were collected. The maximum uptake of technetium-labeled leukocytes was calculated a...

By Stacy Simon Many of the symptoms of colon cancer can also be caused by something that isn’t cancer, such as infection, hemorrhoids, irritable bowel syndrome, or inflammatory bowel disease. In most cases, people who have these symptoms do not have cancer. Still, if you have any of these problems, it is a sign that you should go to the doctor so the cause can be found and treated, if needed:A change in bowel habits, such as diarrhea, constipation, or narrowing of the stool, that lasts for more than a few daysA feeling that you need to have a bowel movement that is not relieved by doing soRectal bleedingDark stools, ...

A 70-year-old man with a 12-year history of ulcerative colitis (UC) underwent a colonoscopy including chromoendoscopy 1 year earlier. Mild proctosigmoiditis was observed with no malignant findings. Surveillance colonoscopy 12 months later revealed an elevated lesion 15 mm in diameter with a central depression in the sigmoid colon (A). CT scan revealed multiple metastatic lesions in the liver, yet no lesion was found on a CT scan performed 4 months before the last colonoscopy (B). Tumor biopsy specimens from both the colon and liver showed solid/nesting poorly differentiated cells with hyperchromatic nuclei and scanty ...
