Positron emission tomography can identify malignant pleural mesothelioma and appears to be a useful noninvasive staging modality for patients being considered for aggressive combined modality therapy.
About one-quarter of cohort completed the entire six-dose treatment. Advancing soft tissue disease was the primary reason for cessation of therapy. The adverse events were mild and manageable. A decline in serum alkaline phosphatase was more common than a decline in PSA.
A 46-year-old woman with advanced ovarian carcinoma had progressive dyspnea and was evaluated with ventilation and perfusion lung imaging. A characteristic pattern of multiple branching perfusion defects of a segmental nature on the perfusion scan suggested tumor microembolism and lymphangitic carcinomatosis. However, in this case, this pattern was associated with pulmonary thromboembolism and was documented by the post mortem examination. Pulmonary thromboembolism should be included among the differential diagnoses in a patient with clinical symptoms and a perfusion scan that reveals multiple branching perfusion defects.
A 55-year-old woman had recurrent bouts of low substernal and epigastric pain radiating into the interscapular region. A hepatobiliary scan initially showed what was believed to be a dilated common bile duct and nonvisualization of the gallbladder. A delayed image obtained after having the patient move about revealed the presence of a filled gallbladder and normal common bile duct. The combination of recurrent pain with this scintigraphic picture may be representative of a floating gallbladder or an incomplete torsion with spontaneous detorsion. This case is presented to describe the scintigraphic appearance of a mobile gallbladder that may be prone to volvulus and to emphasize the importance of obtaining decubitus or oblique views at the end of a hepatobiliary study in selected cases of unusual findings.
An adult female patient presenting with a cystic abdominal mass and intermittent fever, was found at surgery to have a large cyst of the left adrenal gland. The imaging findings and pathology of this uncommon entity are discussed.
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.
