Head CT scan 27 h after thrombolysis shows hypodense lesions in the left basal ganglia and corona radiata without evidence of hemorrhage (a). CT scan of the chest and the heart with contrast shows a large filling defect in the left atrium (b).

A follow-up CT scan revealed hypodense lesions in the left basal ganglia and corona radiata without evidence of hemorrhage (fig. 1a). This finding was confirmed with a CT scan of the chest and the heart (fig. 1b).
A photomicrograph of the 8.0 x 4.7 x 3.7 cm cardiac tumor removed at the operation (a). Microscopically, polygonal and spindle cells were arranged in a single cord or in nests and embedded in the myxoid stroma (HE) (b). The tumor cells show immunoreactivity to calretinin (immunohistochemical stain, anti-calretinin) (c).

There was also a cystic degeneration in the central portion (fig. 2a). In a high-power field, polygonal and spindle-shaped tumor cells were arranged in a single cord or in nests within the myxoid stroma with some capillary-sized vessels (fig. 2b). The tumor cells were calretinin positive and CD31 negative, which differentiate them from endothelial cells of the granulation tissue or endocardial cells (fig. 2c).
