Middle Lobe Torsion after Unilateral Lung Transplant

Abstract

Lobar torsion is well documented after pneumonectomy, but is very rare after lung transplant.  To the best of our knowledge, this is the twelfth reported case of lobar torsion after lung transplant.  In our case, bronchoscopies and chest radiographs were inconclusive; however, CT scan clearly demonstrated findings consistent with right middle lobe torsion.   We review the literature and discuss the epidemiology, clinical presentation, imaging features, and treatment considerations for this condition. We also propose that if a clinical picture could be secondary to torsion and bronchoscopies and chest x ray are inconclusive that a CT scan should be obtained as soon as possible since early recognition increases the likelihood of being able to successfully detorse the lung and avoid lobectomy.
