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).
