title: A case of a migrating pleural lipoma: the beginning of a thoracolith?
abstract: Lipomas can be encountered almost anywhere in the body, yet they are rare in the pleural space of the thorax. However, they have been typically described as pleural-based fatty masses. We present a rare case of a pleural lipoma that changed its location on follow-up images. Migration and rotation of the lesion were investigated using chest computed tomography. A pathologic examination demonstrated extensive calcification and fat necrosis. The findings in this case support a mechanism of development of thoracolith.
