An incidental finding

Mediastinal Haemangioma with Pericardial Effusion: A Rare Entity

“…The incidence is equal in males and females. 1 It is frequently contained in a compartment but may infiltrate adjacent structures. Most occur in the anterior mediastinum and a few in the posterior mediastinum.…”

“…Most occur in the anterior mediastinum and a few in the posterior mediastinum. 1 According to a study of 18 cases of mediastinal haemangioma, 14 were located in the anterior mediastinum and four in the posterior mediastinum. 2 They are classified according to the size of their vascular spaces into capillaries, cavernous or venous haemangioma.…”

“…2 They are classified according to the size of their vascular spaces into capillaries, cavernous or venous haemangioma. 1 It is usually asymptomatic in half of the patients but may present with cough, dysponea, chest pain, stridor or hoarseness of voice in others. Associated lesions in the mediastinum, skin, spleen, liver and kidneys have been recognised.…”

Hemangioma in the posterior mediastinum

“…It shows any of the four types of enhancement after intravenous contrast such as minimal heterogeneous (most common), classical peripheral or central puddling of contrast (common in hepatic hemangioma), homogenous enhancement, and nonenhancement. [9] Nonspecific punctate calcification may be seen which is also seen in teratoma or cartilaginous tumors.…”

“…Delayed images may reveal large draining vein. [9] Low density areas representing fat may be seen in CT scan. MRI of these tumors is often hypointense on T1W1 with few high signal foci due to methemoglobin formation or fat.…”
