title: Spontaneous middle-lobe torsion.
abstract: Middle-lobe torsion is a well documented but rare entity that typically occurs following surgery, characteristically after right-upper lobectomy. It has also been described in the setting of pleural effusion, trauma, and neoplasm. We present a case of spontaneous middle-lobe torsion, occurring in the absence of the above risk factors, with emphasis on radiographic and CT findings.
