title: Thoracic malignant peripheral nerve sheath tumour mimicking a pleural tumour: a rare pedunculated appearance.
abstract: A malignant peripheral nerve sheath tumour (MPNST) generally occurs in adults and often in patients with neurofibromatosis-1 (NF-1). We present a rare case of a huge thoracic MPNST arising from the intercostal nerve in a 12-year-old girl without NF-1. In addition to the unusual occurrence in a child without NF-1, MRI demonstrated a unique pedunculated appearance mimicking a pleural tumour. In this report, we present the CT and MRI findings of our case, together with the histopathological findings, and review previous reports.
