case_images: The right upper lobe tumor was a moderately differentiated lung adenocarcinoma, stage pT2a (see Figure 3).
case_images: Hematoxylin and Eosin, low-power 100x view of solitary fibrous tumor. Mesenchymal neoplasm comprised by spindled cells embedded within a collagen matrix. The tumor is fed by a mixture of small slit-like vessels and large ectatic vessels with a characteristic "staghorn" appearance.

case_images: fig10
case_images: The mitotic rate was significantly elevated at 13 mitotic figures per 10 high-power fields (see Figure 5). The tumor matrix was predominantly myxoid, and the cells were fed by a rich vascular network of small slit-like vessels and large ectatic branching vessels (see Figure 10).
case_images: Multiple views of the Gamma Knife treatment plan with 22 Gy prescribed to the periphery of the tumor cavity, and this correlates with the 50% isodose line (dose representations are overlayed on a brain MRI from the day of treatment).
