GI / GU Flashcards
Case 60
What type of ulcer suggests Crohn’s rather than Ulcerative Colitis?
Aphthous Ulcers
Case 9
What is clubbing of gastric folds?
Indicative of a malignant ulcer
- the termination of a fold swells in to a club like configuration
Case 30
What is Carmen meniscus sign and what does it indicate?
How is CMS best seen?
A large semilunar hypodense zone
- may be seen in ulcerated gastric adenoCA - flattened polypoid mass with a broad central ulceration - gastric mucosa adjacent to the polyp forms a smooth inner margin
Single contrast or biphasic study
Case 9
Define Hampton’s Line
Thin well defined lucency seen at the base of an ulcer
- An ulcer collar
- Indicative of benign gastric ulcer
Case 48
What is the moulage sign and what is it associated with?
Barium forms smooth, featureless elongated columns or clumps in the jejunum
- Seen on SBFT
- Associated with celiac dz
Case 49
What is the ringed esophagus associated with?
Eosinophilic Esophagitis
Case 51
Through what anatomic area does the hernial sac pass in a spigelian hernia?
Linea semilunaris
- Joins rectus and oblique muscles
- Possible congenital weakness at junction
Case 51
What is a Littre Hernia?
A hernia containing a meckel diverticulum
Case 54
What is Menetrier’s disease?
Rare disease characterized by gastric mucosal hypertrohpy
- Giant rugal folds
Case 56
How can radiating folds help determine whether a gastric ulcer is benign or malignant?
Likely benign if
- smooth radiating folds extend to the center of the edge of the crater
Case 15
What is pneumatosis intestinalis cystica?
Benign condition with subserosal blebs in the distal bowel
Case 38
Define bull’s eye lesion
Rounded filling defect with a barium collection at its center (ulceration)
Case 30
What is the Kirkland complex?
Concave luscent margin around the ulceration in ulcerated gastric cancer
Case 42
Describe Esophageal Intramural Pseudodiverticulosis
Barium filling of normal excretory ducts of the mucous glands of the esophagus, which are dilated by an underlying inflammatory process
- May result in benign strictures
- Slightly increased risk of adenoCA
Case 36
What is glycogenic acanthosis?
Benign condition of the esophagus with nodular swelling of the epithelium
- Occurs in elderly
- Not clinically important
What is Whipple’s Dz?
- Rare systemic infectious disease
- Bacterium Tropheryma whipplei
- Primarily malabsorption but may affect heart, brain, joints, skin, lungs eyes
- Weight loss, diarrhea, joint pain, and arthritis
- Significantly more common in men, 87%
- Can usually be cured with long-term antibiotic therapy
- Untreated, the disease is ultimately fatal
