摘要: OBJECTIVE. Stromal tumors are an important cause of occult gastrointestinal bleeding in patients who middle aged or older. This study evaluated the size at which stromal become symptomatic and necrotic examined role limitations multidetector CT detecting tumors.MATERIALS AND METHODS. Two hundred seventy-one with were retrospectively studied to examine symptomatic, necrotic, malignant tumors. Next, five asymptomatic family members germline c-kit mutations prospectively screened evaluate CT.RESULTS. In this retrospective study, two thirds had symptoms signs that correlated tumor size. larger than 3 cm accompanied by necrosis, whereas finding was rare for those smaller cm. prospective screening, IV infusion contrast material showed gastrointes...
