She denied previous history of trauma or surgery. Computed tomography (CT) pulmonary angiography showed a paravertebral, soft tissue mass which raised suspicion of a pleural tumor. In the coronal plane, the mass was protruding to the abdomen and had similar density with liver. Magnetic resonance imaging confirmed the diagnosis.
