14) When the thymus extends into the lower neck or retrocaval region, its texture should be identical to that of the normal thymus located in the anterior mediastinum
In the unsuccessful cases, the glands were located in the lower part of the anterior mediastinum
, below the innominate vein, and could not be retrieved through a transcervical thymectomy because the glands were not inside the thymus or because of leakage of the thymic tissue during the procedure.
Interquartile ranges of perfusion parameters for subtypes of anterior mediastinum
lesions BF BV PS Thymic hyperplasia 33.
Nearly all benign teratomas have been observed to develop in the anterior mediastinum
This mass was found in the anterior mediastinum
and the result of frozen section was in favor of adenoma.
In adults 65% of lesions arise in anterior mediastinum
, 10% in middle mediastinum and 25% in posterior mediastinum.
Subsequent contrast-enhanced computed tomography (CECT) of the chest revealed homogenous enlargement in the anterior mediastinum
, and the thymoma was highly suspected accordingly.
Because, they had epicenter or major component in anterior mediastinum
1 Thymomas and germ cell tumours are most common lesions in anterior mediastinum
while lymphomas, mediastinal cysts, and neurogenic neoplasms are the most common primary middle and posterior mediastinal tumours.
An irregular mass (7x3x3 cm) was found in the anterior mediastinum
arising from the thymus.
CT of the thorax revealed a 4 x 7-cm mass lesion adjacent to the anterior mediastinum
that could not be separated from the aorta and pulmonary trunk (figure 3, B).
The chest CTA was negative for pulmonary emboli but incidentally demonstrated a homogenous 5 cm mass in the anterior mediastinum
(Figures 1 and 2).
