Solitary necrotic nodules of the liver: cross-sectional imaging findings and follow-up in nine patients.
OBJECTIVE. The purpose of our study was to retrospectively evaluate the sonographic, CT, and MRI findings (number, diameter, lobar location, depth from the hepatic capsule, and appearance of lesions) in a series of nine patients with pathologically proven solitary necrotic nodules of the liver and the natural evolution at follow-up in four of the nine patients.CONCLUSION. Solitary necrotic nodules are usually small, solitary lesions, mainly located under the liver capsule of the right lobe. They are hypoechoic on sonography, hypoattenuating on CT, have low signal intensity on both T1- and T2-weighted MRI with lack of enhancement after IV contrast administration, and at follow-up have a tend…
Italian survey of second tumors in patients with diagnosis of GIST (gastrointestinal stromal tumor).
11032 Background: GISTs are the most common mesenchymal tumors of the digestive tract. As of recent, new links are being made between GISTS and secondary malignancies. However, whether the coexistence of GISTs with other tumors is stochastic, or the result of related pathogenetic mechanisms is still unknown. Methods: We retrospectively reviewed clinical and molecular features from all GIST patients with second tumors treated in seven Italian GIST reference centers. Qualitative variables were compared using the Fisher exact test. Results: Clinical data of 184 patients with diagnosis of GIST were evaluated. Median age at diagnosis was 66 years, KIT exon 11 resulted the most frequent mutation…
