Objectives: After studying the article entitled “Sonographic Detection of a Gastrointestinal Stromal Tumor of the Stomach,” you will be able to:
Describe the sonographic features of a gastrointestinal stromal tumor
Correlate sonographic findings with other imaging modalities for the evaluation of a gastrointestinal stromal tumor
Describe the commonly found mesenchymal tumors of the gastrointestinal tract
Most commonly, if a gastrointestinal stromal tumor recurs, it will be within ________ years following resection. 1 to 2 2 to 4 3 to 5 6 to 8
The mean age at which gastrointestinal stromal tumors occur is ____ years. 40 63 70 82
Most often gastrointestinal stromal tumors are Benign and slow growing Benign but rapidly growing Malignant with minimal vascularity Malignant and rapidly growing
Approximately what percentage of gastrointestinal stromal tumors are found within the small intestine? 20% to 30% 30% to 40% 50% to 60% 60% to 70%
Typical modalities used to detect and diagnose gastrointestinal stromal tumors include Magnetic resonance imaging, plain film radiography, and sonography Computed tomography, sonography, and open surgical biopsy Computed tomography, magnetic resonance imaging, and plain film radiography Computed tomography, sonography, and fine-needle aspiration
Sonographically, gastrointestinal stromal tumors typically appear to be Well-circumscribed masses without vascularity Well-circumscribed masses predominantly hyperechoic Well-circumscribed masses with mixed gray-scale levels Hyperechoic masses with poorly defined margins
Most duodenal tumors are Mesenchymal Endothelial Epithelial Squamous cell
Gastrointestinal stromal tumors are found as asymptomatic masses in approximately what percentage of cases? 70% 50% 40% 20%
The tumor location with the best prognosis for successful treatment is in the Gastroesophageal junction Fundus of the stomach Antrum of the stomach Distal duodenum
Of malignancies associated with the gastrointestinal tract, gastrointestinal stromal tumors comprise <1% 2% to 3% 3% to 4% >5%
