Figure 2From: Solitary fibrous tumors of the soft tissues: imaging features with histopathologic correlationsUnenhanced CT (A) demonstrates a deep soft tissue mass in the left paravertebral area (asterisk). The mass is isodense compared to muscle. No bone erosion is observed. At 30 s post-contrast infusion (B) the lesion exhibits mild heterogeneous enhancement while at 90 s post-contrast infusion (C) the lesion shows more intense homogeneous and prolonged enhancement.Back to article page
