Imaging Studies

CT scan detects an oval or round shaped, sharply marginated, homogenous lesion. Uptake of contrast medium by this tumefaction is highly variable and has limited diagnostic value. Computerized tomography should not be solely relied upon since it does not allow one to make a definitive diagnosis.

Ultrasound study can find a uniform high-echogenicity on A-scan. These reflections are secondary to the septae found within the lesion. Doppler flow study may reveal subdued blood flow within the angioma. [4]

Histologic Findings

Histopathologic study finds engorged vascular channels, which are tightly knit and separated by fibrous septae. These channels can have diameters measuring 1 mm and are lined by a single layer of endothelial cells.
