SWE allows the elastic properties of the calcaneal tendon to be evaluated quantitatively in vivo, but interobserver reproducibility is questionable. It confirms the tendinous elastographic anisotropy and stiffness augmentation of stretched tendon.
The CT scan can play a role in diagnosing malignant ascites. We confirm the usefulness of the indirect signs composed of distribution of ascites fluid, thickening and enhancement of the parietal peritoneum, and loss of mobility of the bowel loops in the ascites.
We report the case of a 27-year-old woman referred to our department for the characterization of a 7 × 6-cm left ischio-anal fossa mass by Ga-DOTATOC PET/CT. Several diagnoses were previously mentioned, in particular, myxoid sarcoma but also pelvic paraganglioma. Urinary methoxylated derivates and blood chromogranin A tests were negative. PET/CT showed a high Ga-DOTATOC uptake of the mass that was strongly consistent with paraganglioma diagnosis. Histopathological analysis surprisingly revealed a solitary fibrous tumor without aggressive criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
