Fig 1. A 55-year-old woman presented with headache and vomiting with left lateral ventricular mass.
A, Axial nonenhanced CT image of the brain at the level of the atrium and body of the lateral ventricles shows a lobulated left ventricular mass with peripherally situated foci of calcification. There are focal areas of hyperattenuation and hypoattenuation in the lesion.
B, Axial contrast-enhanced CT image of the brain at the level of the body of the lateral ventricles reveals a lobulated left ventricular mass with intense but heterogenous enhancement with a central nonenhancing area.
C, Photomicrograph illustrates fascicular arrangement of spindle-shaped tumor cells (arrows) with attenuated intercellular collagen (hematoxylin-eosin, 400x).
D, Photomicrograph illustrates CD34 immunopositivity in the tumor, which is compatible with a diagnosis of solitary fibrous tumor (avidin peroxidase, 400x).
