Laboratory Studies
- Immunohistochemical staining is positive for factor VIII.
Imaging Studies
- Neuroimaging studies can be of great assistance in establishing the diagnosis.
- Ultrasonography shows a lesion with irregular contour and low-to-medium internal reflectivity.
- CT scan reveals a poorly circumscribed mass with no bony erosion. The lesion usually enhances with intravenous contrast.
- Magnetic resonance imaging (MRI) reveals a lesion that is hypointense to fat on T1-weighted scans and hyperintense to fat on T2-weighted scans.
- A well-circumscribed lobular pattern with prolonged parenchymal staining is seen with angiography. Involuting lesions tend to have less tissue staining.
Histologic Findings
Pathological findings include proliferation of a single layer of endothelial cells and pericytes. Endothelial cells of the basement membrane characteristically have large amounts of endoplasmic reticulum. The small vascular spaces lead to the formation of a high-flow lesion.
