Quizplus · Accepted Answer

The description suggests the presence of large conglomerate masses that are migrating asymmetrically towards the lung hilum.

Neither progressive systemic sclerosis nor adult respiratory distress syndrome is associated with this radiological pattern, and benign pneumoconiosis is a nonspecific term that does not describe the specific imaging findings described here.
