A Rare Anatomical Variation: Intrathoracic Liver Caudate Lobe: A Case Report.

We present a case with an intrathoracic caudate lobe in a 45-year-old woman who referred with a complaint of nonspecific chest pain. 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.
