![]() In which the ends correspond to small bowel loops retracted by the mass. This mass resembles sometimes to bicycle handlebars, Usually near the primary tumor (Figure 22). Mesenteric metastases are typically presented as contours heterogeneous spiculated mass (due to intense desmoplastic reaction), Such as metastases or mesenteric lymph nodes. The most common form of detection is through their secondary findings, Therefore they are not usually detectable with conventional CT or MRI techniques.ĬT and MR enterography or enteroclysis have demonstrated a high sensitivity (100% and 86-94% respectively) and specificity (96.2% and 95-98%). Or hypervascular parietal concentric or asymmetrical thickening. Overall the sensitivity increases with increasing tumor size and specificity decreases with lesions with atypical features.ģ0% of NETs in gastrointestinal tract are located in the ileum, The sensitivity and specificity of CT and MRI in the NET is comparable (93% and 88%),īut MRI is more sensitive in liver metastases detection and CT in pancreatic head tumors. The use of ultrasound contrast may be considered in certain cases. In the initial diagnosis of NETs CT or entero CT is used,įor staging and monitoring of disease CT or MRI and scintigraphy with somatostatin receptors, The most common form of detection is through its secondary findings or mesenteric lymph nodes metastases. NETs settle more often in the digestive tract, ![]() With an incidence of 1.6-2 new cases per 100,000 people per year. NETs represent between 1.2 -1.5% of all gastrointestinal malignancies, ![]()
