Diagnosis With Brief Discussion

Diagnosis
Venous hemangioma
Radiologic Findings
1. Chest X-ray: Bulging opacity is noted in the right paratracheal area and left pericardial area
2. Chest CT: Low attenuating lesion involving middle and anterior mediastinum. This lesion encases arch vessels, aortic arch and pericardium. However, there’s no definite evidence of vascular obstruction or post obstructive dilatation. And it show homogenously low attenuation without definite enhancement.
3. Chest MR: Mediastinal mass shows bright high signal intensity on T2WIs and some dark signal intensity component is noted in the left side of the mass lesion. However there’s no enhancement on T1 contrast enhanced MR image, even the low SI component on T2WIs.
 Differential diagnosis: lymphangioma, capillary hemangioma
4. Bilateral mediastinal VATS excision:
• Tortous and dilated blood vessels
• Consistent with Venous Hemangioma
Brief Review
Mediastinal hemangiomas are rare vascular tumors, less than 0.5% of all the masses found in the mediastinum. It is composed of large interconnecting vascular spaces lined with flat endothelial cells, and the vascular spaces are filled with blood. And over 90% of these tumors are cavernous or capillary hemangiomas. And venous hamangiomas are extremely rare, approximately 1% of all mediastinal hemangioma.
The tumors are categorized according to the size of their vascular spaces as capillary, cavernous and venous hemangiomas.
