title: Rounded atelectasis shown by computerized tomography.
abstract: We have reported a rounded atelectasis in a 65-year-old man. On CT scan a pleural-based mass was associated with curved, ragged projections from the lower pole of the lesion. This phenomenon appears to be the counterpart of the so-called comet tail on regular tomography and, because of its clarity, may further facilitate the diagnosis of this entity.
