Churg-Strauss syndrome is a rare systemic disease primarily characterized by
hypereosinophilia, asthma and vasculitis. The lung is the organ most frequently
involved. In the present report, the authors describe a relatively rare finding in
this disease - the presence of a pulmonary nodule -, while recalling the main
radiological findings and the most relevant differential diagnoses.
The authors report a case of a 48 year-old female patient with moderate abdominal
pain and bulging in the abdomen. Physical examination demonstrated the presence of a
palpable abdominal mass. Computed tomography showed a heterogeneously enhancing
retroperitoneal mass in close contact with the inferior vena cava. En bloc resection
of the mass and of the attached vena cava segment was performed. Histological
analysis revealed leiomyosarcoma.
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.
