Acute necrotizing eosinophilic myocarditis in a patient taking Garcinia cambogia extract successfully treated with high-dose corticosteroids.

A previously healthy 48-year-old woman was evaluated for lightheadedness and chest heaviness 2 weeks after starting the herbal supplement Garcinia cambogia. She was found to be hypotensive and had an elevated serum troponin level. The patient had a progressive clinical decline, ultimately experiencing fulminant heart failure and sustained ventricular arrhythmias, which required extracorporeal membrane oxygenation support.

Renal masses: quantitative assessment of enhancement with dynamic MR imaging.

Purpose: To establish a quantitative magnetic resonance (MR) imaging contrast enhancement criterion for distinguishing cysts from solid renal lesions.

Materials And Methods: Regions of interest were measured in 74 patients with renal lesions evaluated by means of dynamic contrast material-enhanced MR imaging with serial breath-hold spoiled gradient-echo acquisitions. Sensitivity for renal tumors and specificity for renal cysts were established by using percentage of enhancement thresholds that varied between 5% and 35%.
