Jun 8, 2009 S. R. Different Patterns of Colonic Tumors in Barium Studies S. Rad Selected Cases from the Personal File Tabriz Med. Sc. University

Jun 8, 2009 S. R. According to the appearance of the tumors in barium studies they are categorized in different types. Followings are some examples for each type.

Jun 8, 2009 S. R. Polypoid or Fungating types: They produce bulky mass invading some part of the colonic lumen and are demonstrated as the genuine filling defects. They stand usually in the places where there is enough room for them to expand such as rectum and cœcum.

Jun 8, 2009 S. R. Filling defect shows the intraluminal part of the tumor Tumor mass may not be seen in barium study but in the CT, US or MR scans

Jun 8, 2009 S. R. Barium studies delineate only the intra-luminal component of the tumor and to see the whole extent of the tumor we have to implement cross-sectional imaging.

Jun 8, 2009 S. R. Extraluminal component of the tumors may be small like carcinomas or large and bulky such as in sarcomas or lymphomas.

Jun 8, 2009 S. R. Polypoid tumor with intussusceptions

Jun 8, 2009 S. R. Fecal impaction in the ascending colon was noticed in the preliminary scout film we usually take before barium enema. To follow …

Jun 8, 2009 S. R. … Fecal impaction ( on the right) did not allowed barium filling, so we did barium meal ( on the left) and bulky tumor was shown in this film.

Jun 8, 2009 S. R. Barium was expelled and this film was taken after that.

Jun 8, 2009 S. R. Metastatic gall-bladder carcinoma in the colon.

Jun 8, 2009 S. R. Metastatic urinary bladder carcinoma.

Jun 8, 2009 S. R. Annular Constricting types: They show usually the shortest filling defects among colon tumors. Initially they invade unilaterally the lumen to become annular around it and produce typical apple core pattern.

Jun 8, 2009 S. R. Apple core pattern and typical shouldering of the margins

Jun 8, 2009 S. R. Dilatation of the proximal segment after a while. Apple core pattern

Jun 8, 2009 S. R. Acute marginal angles or shouldering sign may disappear proximally because of its dilatation

Jun 8, 2009 S. R. Once again double contrast doesn’t show the tumor but the meal did it from the pother way

Jun 8, 2009 S. R. Infiltrating or scirrhous types: They are having more or less long segment without clear-cut margins with the neighborhood and are very alike inflammatory processes and are sometimes hard to discriminate.

Jun 8, 2009 S. R. Ulcerating types: Characteristic meniscus sign is the milestone for diagnosis of these types and they don’t differ from the malignant ulcers in the other parts of the gastro-intestinal tract concerning the overall configuration.

Jun 8, 2009 S. R. Meniscus Ulcer

Jun 8, 2009 S. R. Mural and submucosal types: They appear as the external compression effects on the barium column unless they invade lumen in some way. All sarcomas behave in this manner.

Jun 8, 2009 S. R. Fibrosarcoma of the hip

Jun 8, 2009 S. R. Lymphatic mass

Jun 8, 2009 S. R. Tumor itself is not seen Tethering caused by adhesion Ragged and smooth contour

Jun 8, 2009 S. R. Adhesion of the mass to the colonic wall

Jun 8, 2009 S. R. Metastatic Hepatoma Gall-bladder tumor invading colon

Jun 8, 2009 S. R. Metastatic hepatoma

Jun 8, 2009 S. R. Metastatic breast carcinoma

Jun 8, 2009 S. R. Mixed types: They share all appropriate characters explained for the unique types and are diagnosed easily because of detailed analytic interpretation.

Jun 8, 2009 S. R. Ileo-rectostomy following total colectomy

Jun 8, 2009 S. R. Entero-colostomy after hemicolectomy

Jun 8, 2009 S. R. For hepatic metastasis we use CT scanning or Ultrasonography and occasionally chest x-ray for rectal tumor in cloacogenic type.

Jun 8, 2009 S. R. Conclusion Diagnosis of the tumors in the colon is usually straight forward if the fluoroscopy is implemented. In fact detection of the tumors is made by searching every corner of the colon and spot-films are the first step to register them during the examination. The only difficulty remains in discrimination of the infiltrative carcinoma and inflammatory processes. This will demand a bit of experience of course.

Jun 8, 2009 S. R. Thanks for your attention
