Abstract:
We report a case of left upper lobe torsion in a patient who had a pneumothorax as a complication of subclavian venous access for an elective neurosurgical operation. Despite appropriate management of the pneumothorax, the patient's chest radiograph did not improve. Computed tomography of the chest was concerning for left upper lobe torsion. Fiberoptic bronchoscopy revealed near complete obstruction of the left upper lobe bronchus. Review of computed tomography imaging before and after bronchoscopy and subsequent thoracotomy confirmed lobar torsion. Consideration of lobar torsion in the differential diagnosis of patients with persistently abnormal chest imaging despite appropriate management after complications of routine procedures is important for early recognition and intervention of a potentially life-threatening problem.

Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Pneumothorax-II
Clinical Manifestations:
Torsion of Noncircular Members
Torsional Pendulum
As long as the rigid body's angular displacement is small, its oscillation can be modeled as a linear angular oscillation. The amplitude of the oscillation is an angle. The role of mass is played...
Bending and Torsional Moments
The reaction developed in a structural element when subjected to an external force causes the element to bend. When a structural element bends upwards, it creates compressive normal forces on the top and tensile normal forces on the bottom, resulting in a couple that determines the bending...
