Untitled Deck Flashcards
What is the most common type of lung cancer? (Webb Thoracic Imaging: Pulmonary and Cardiovascular Radiology Third Edition, Sec. 2 Ch. 4 p. 336)
Adenocarcinoma
Which of the following malignancies will most likely present with calcific pulmonary metastases? (Webb Thoracic Imaging: Pulmonary and Cardiovascular Radiology Third Edition, Sec. 2 Ch. 5 p. 502)
Mucinous adenocarcinoma
Calcification of metastases occurs most commonly with osteogenic sarcoma, chondrosarcoma, synovial sarcoma, thyroid carcinoma, and mucinous adenocarcinoma (Fig. 5.5). Calcification may be dense, particularly with osteogenic sarcoma, mimicking a granuloma. Calcification may persist following successful chemotherapy despite resolution of the tumor.
Which type of tumor is most commonly associated with pleural metastases? (Webb Thoracic Imaging: Pulmonary and Cardiovascular Radiology Third Edition, Sec. 2 Ch. 5 p.540)
Adenocarcinoma
Mediastinal lymph node involvement is the most common thoracic abnormality in patients with Non-Hodgkin Lymphoma. Which compartment is most often involved (75%)? (Webb Thoracic Imaging: Pulmonary and Cardiovascular Radiology Third Edition, Sec. 2 Ch. 6 p.588)
Superior mediastinal
Most common form of emphysema characterized by airspace distention in the central portion of the lobule, with sparing of their more peripheral portions. This form affects the upper lobes more than the lower lobes. (Brant, 4th ed. p. 497)
Centrilobular emphysema
The most important plain radiographic finding seen in patients with emphysema (Brant, 4th ed. p. 499)
Absent or attenuated peripheral vascular markings
The most common etiologic factor for the development of emphysema (Brant, 4th ed. p. 498)
Smoking
In traumatic injuries of the trachea and main bronchi, which is the most commonly involved part? (Brant, 4th ed. p. 492)
proximal main bronchi
- The fractures gen- erally involve the proximal main bronchi (80%) or distal tra- chea (15%) within 2 cm of the tracheal carina
- Penetrating tracheal injuries usually involve the cervical trachea and result from gunshot or stab wounds to the neck.
It is the most common malignant mediastinal germ cell tumor (Webb Thoracic Imaging, 3rd ed, p690)
Seminoma
The most common foregut duplication cysts can be present in any part of the mediastinum, but is most commonly located where? (Webb Thoracic Imaging, 3rd ed, p777)
Subcarinal
True of intralobar pulmonary sequestration (Webb Thoracic Imaging, 3rd ed, p927)
Drainage via pulmonary veins in most
Does not have own pleura, Arterial supply - thoracic aorta, late childhood, Drainage vie pulmonary veins
What lobe is most commonly affected in congenital lobar overinflation? (Webb Thoracic Imaging, 3rd ed, p897)
Left upper lobe
Most commonly associated with the feeding vessel sign (Webb Thoracic Imaging, 3rd ed, p977)
Metastasis
The “feeding vessel sign” is present if a small pulmonary artery is seen leading directly to a nodule (Fig. 9.12). This appearance is most common with metastasis, infarct, and AVM. It is less common with primary lung carcinomas or benign lesions such as granuloma. If present, it should suggest the possibility of a vascular abnormality, but is nonspecific.
his drug is the most common cause of pulmonary toxicity related to chemotherapy: (Webb 3rd ed., p 1619)
Bleomycin
Radiation pneumonitis is most severe ______ following completion of treatment. (Webb 3rd ed., p 1624)
3-4 months
It is the most frequent thoracic manifestation of asbestosis. (Webb 3rd ed., p 1649)
Pleural disease
The tracheo-esophageal stripe represents the combined thickness of the tracheal and esophageal walls and intervening fat. It normally measures less than 5 mm. Thickening is most commonly seen in ___. (Brant, p. 329)
esophageal carcinoma
NOT esophagitis, esophageal varices
The interface of the right upper lobe (RUL) with the right lateral tracheal wall is called the right paratracheal stripe (Fig. 12.4A). This stripe should be uni- formly smooth and should not exceed 4 mm in width; thick- ening or nodularity reflects disease in any of the component tissues, including medial tracking pleural effusion. The left lateral wall is surrounded by mediastinal vessels and fat and is not normally visible radiographically. The posterior trachea can be visualized on the lateral chest (Fig. 12.4B). The pres- ence of air in the esophagus produces the tracheoesophageal stripe, which represents the combined thickness of the tracheal and esophageal walls and intervening fat. This stripe should measure less than 5 mm; thickening is most commonly seen with esophageal carcinoma.
This is the most common accessory lung fissure. (Brant, p. 331)
Inferior accessory fissure
All of the following refer to usual interstitial pneumonia, EXCEPT (Webb 3rd ed., p 1391)
a. Most common interstitial pneumonia
b. Spatial and temporal inhomogeneity
c. Subpleural sparing
d. Dense fibrosis, often with honeycombing
c
subpleural sparing is a feature of NSIP
Most likely cause of unilateral upper lobe bronchiectasis? (Webb 3rd ed, p. 1911-1912)
tuberculosis
