Use of FDG-PET/CT for peritoneal carcinomatosis before hyperthermic intraperitoneal chemotherapy.

Background: Peritoneal carcinomatosis (PC) is associated with a very poor prognosis. Complete cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy has been shown to improve survival rates of PC. However, this treatment is beneficial for patients if the complete cytoreductive surgery is macroscopically completed before implementing hyperthermic intraperitoneal chemotherapy.

Uncommon breast tumor attenuation artifact on radionuclide ventriculography.

A 39-year-old woman with locally advanced left breast cancer (T4 N0 M0) underwent equilibrium radionuclide ventriculography for baseline assessment of left ventricular function before neoadjuvant chemotherapy. The left ventricular ejection fraction was 76% at 75 beats per minute, without localized wall motion abnormality. In the best septal left anterior oblique projection, a large photopenic "halo" surrounded the cardiac chambers, mimicking a pericardial effusion.
