title: Paraesophageal omental hernia mimics pleural lipomatous tumor.
abstract: Paraesophageal omental herniation (POH) is uncommon. CT scan and MRI are complementary in diagnosis. We present a posterior mediastinal mass in a 43 year old male with a history of myxoid liposarcoma raising the suspicion of latent secondary tumor. Subsequently, at thoracotomy he was found to have a POH. Differential diagnosis, work-up and surgical approach are discussed.
