MDCT ANGIOGRAPHY OF THE THORACIC AORTA
HISTORY: Check-up and CXR found widening mediastinum. R/O mediastinal mass or
aortic aneurysm.
TECHNIQUES: Axial helical scan of the whole aorta with 2-mm slice thickness.
The scan phases included: plain, CTA and venous
FINDINGS:
CTA
Aorta: No aneurysm or dissection.
Aortic branches: No aneurysm or dissection.
Periaortic tissues: No periaortic/mediastinal hematoma, pericardial or pleural effusic
No contrast extravasation from the aortic lumen.
Pulmonary artery: The MPA, RPA and LPA measure 26 mm, 20 mm and 20 mm in
diameter, respectively.
CHEST
g parenchyma: Multiple non-calcified pulmonary nodules at posterior seg
(4mm,Im 96/295), lateral segment of RML (4 mm, Im 130/295), infer
of LUL (5mm, Im 1571295) and posterior basal segment of LLL
202/295).
Central airways: Normal.
Pleural cavity: No pneumothorax or effusion.
Heart: Borderline heart size. No pericardial effusion.
Mediastinum and hila: Multiple lymph node enlargement at right upper and lower
paratracheal, prevascular, subaortic and paraaortic regions, measuring up to
4.2x3.4x3.3 cm at right lower paratracheal region.
Chest wall and lower neck: Normal visualized thyroid gland. No axillary or
supracalvicular lymph node enlargement.
Visualized upper abdomen: Unremarkable.
Bony structures: No suspicious lytic or blastic lesion.
IMPRESSION:
- No dissection or aneurysm of thoracic aorta.
- Multiple mediastinal lymphadenopathy. Lymphoma should be considered, please
correlate with tissue diagnosis and clinical context. DDx included hematologic
malignancy, infection and metastasis.
Multiple non-calcified pulmonary nodules at RUL, RML, LUL and LLL, size 4-5 mm,
indeterminate nature.
