Abstract

Cavernous hemangiomas of the mediastinum are rare tumors that usually occur in young patents. We present a case of cavernous hemangioma in a 12-year-old girl. This case was seen as nonenhancing cystic mass on CT, mimicking lymphangioma. US demonstrated a hyperechoic mass, while MRI revealed a T2 high SI with delayed homogenous enhancement. US and MRI were found to be useful tools for the diagnosis of hemangiomas, seen as a cystic mass on a chest CT scan.

Fig. 1

Chest radiograph demonstrates bilateral superior mediastinal mass, prominent in right side.

Chest CT images of a 12-year-old girl with mediastinal hemangioma.

A. Precontrast CT scan reveals low attenuating mediastinal mass (mean 40 HU) without phlebolith, surrounding great vessels and trachea.
B. Postcontrast CT scan shows little enhancement of the mass and right pleural effusion.

Sonography shows hyperechoic mass (M) in posterior to thoracic great vessels.

Chest MRI images of a 12-year-old girl with mediastinal hemangioma.

A. Axial T1-weighted MRI shows heterogenous low to iso-intensity mass relatively hypointense to the skeletal muscle.
B. Axial T2-weighted MRI shows high-intensity mass with multiple structures of tubular signal voiding.
C. Axial dynamic enhanced T1-weighted MRI at 60 seconds reveals no enhancement of the mass.
D, E. Axial and coronal enhanced T1-weighted MRI after 60 minutes show diffuse, strong enhancement of the mass.

Histopathological features of mediastinal hemangioma.

A. The cut surface shows various sized spaces containing blood clots.
B. The tumor is composed of various sized blood vessels or irregular vascular spaces lined by endothelial cells (H & E, ×100).
