Question:

Which of the following is not a characteristic CT feature of BAC?
1. Air bronchograms.
2. Pseudocavitation.
3. Calcification.
4. Ground glass opacification.
5. CT angiogram sign.





Answer:

The correct answer for the question "Which of the following is not a characteristic CT feature of BAC?" is:

3. Calcification.



Explanation
Calcification is not a characteristic feature of BAC. [Early focal formerly BAC may have three appearances on CT: 1) pure ground glass opacification (GGO), appearing as hazy increase in attenuation without obscuration of bronchovascular markings; 2) solid, with complete obscuration of bronchovascular markings; 3) mixed, with both of the above components... Advanced disease may be unifocal or multifocal, with pseudocavitations and air-bronchograms. The CT angiogram sign may be present in contrast-enhanced CT...]

Abstract
We describe the case of late recurrence of a focus of invasive mucinous adenocarcinoma (formerly mucinous bronchioloalveolar carcinoma) following radiofrequency ablation, despite a negative positron emission tomography/computed tomography scan at 13 months following the ablation. A computed tomography scan performed at 24 months demonstrated unequivocal recurrence of the lesion. Combined positron emission tomography/computed tomography has been described as an adequate modality for the follow-up of thermally ablated pulmonary lesions. However, its utility in the follow-up of well-differentiated pulmonary adenocarcinoma may be limited. Lesion activity may be underestimated by an inherently low metabolic activity. Small lesions may also be susceptible to partial volume effect. Long-term imaging follow-up of well-differentiated pulmonary adenocarcinoma beyond two years after thermal ablation is prudent to avoid missing late recurrence.
