Case Discussion

Routine erect PA and lateral chest radiographs were ordered, although had no chest-related complaints or a history of cardiopulmonary disease. Radiographs were normal, except for an old malaligned right mid-clavicular fracture and right lateral osteophytes in several consecutive thoracic vertebrae. Incidental finding of left horizontal fissure.

Non-contrast-enhanced CT (NECT) performed previously for protracted chest pain and fatigue revealed no chest pathology, but demonstrates left horizontal fissure nicely.
