Mucosa-associated lymphoid tissue (MALT) lymphoma is predominantly found in the stomach. Rarely, it is found in the proximal colon and even less so in the sigmoid colon. We present a rare case of primary sigmoid colon MALT lymphoma in a patient with concomitant Helicobacter pylori and hepatitis C infection. We also review current imaging, staging, and therapeutic modalities. To our knowledge, t...

a 78-year-old woman with a history of colon cancer with metastasis to the liver was presented to our emergency department because of bilateral groin pain and difficulty in walking, which had gradually increased during the previous 5 days. the pain was of sudden onset, radiating to the back, without aggravating or relieving factors. it was associated with constipation, dysuria and vaginal discha...

Colonoscope looping in the sigmoid colon is ...

BACKGROUND We have previously recognized segmental sigmoid polyps as an indicator of a fistula from Crohn's ileitis to the sigmoid or the proximal rectum. In the course of this study, we realized that many patients with this fistula had no sigmoid polyps, but the sigmoid was the site of marked inflammation and early or late stricture formation. Furthermore, in some patients with a stricture, th...

Background: Sigmoid volvulus is a rare complication in pregnancy. The clinical presentation is similar to that of non-pregnant volvulus, although the symptoms can be masked by the enlarged uterus and physiological changes during pregnancy and it can be challenged and delayed in diagnosis and treatment. Delay in diagnosis can also lead to ischemia, necrosis and perforation of the intestine, whic...

The separation of a filament and sigmoid is observed during an X1.4 flare on July 12, 2012 in solar active region 11520, but the corresponding magnetic field change not clear. We construct data-constrained magnetohydrodynamic simulation filament-sigmoid system with flux rope insertion method eruption code, which produces evolution that may explain low-lying high-lying hot channel (sigmoid). ini...

the most common metastatic sites for colorectal carcinomas include the liver, lungs, brain, bones and peritoneal surfaces. in this report, a case of sigmoid colon carcinoma presented with cervical lymphadenopathy was detected with the help of pet/ct. a 57 year-old male presented with a complaint of swelling on the left side of his neck. ultrasonographic examination of the neck revealed three hy...

Fractures of the distal radius are among the most common injuries of the upper extremity, though treatment has traditionally focused on restoration of the radiocarpal joint and late sequelae may persist. X-ray imaging underestimates sigmoid notch involvement following distal radius fractures. No classification system exists for disruption patterns of the sigmoid notch of the radius associated w...

A conformity bias is, in cultural evolutionary terms, an individual-level tendency to disproportionately copy the majority. Collectively, at population-level, this individual behaviour results in a characteristic sigmoidal relationship between the frequency of the behaviour in the population and the probability to copy it (“the sigmoid”). In two recent papers (Acerbi et al. 2016, van Leeuwen et...

BACKGROUND The optimal treatment of acute complicated diverticulitis is a matter of debate and has undergone significant changes. Currently, the main focus of surgical treatment concepts is on controlling the emergency situation triggered by acute complicated sigmoid diverticulitis through interventional and minimally invasive measures. METHODS This article presents the current data and recom...
