MPNSTs (malignant peripheral nerve sheath tumors) are a highly malignant group of soft tissue sarcomas and carry a very poor prognosis. Metastasis to bilateral adrenal glands is very rare in such group of neoplasms. We discuss a case of 85-year-old man who was diagnosed with MPNST from prevertebral mass with metastases to bilateral adrenal glands and bone marrow from the beginning and role of serial 18F-FDG PET/CT scans in response assessment first to sunitinib (tyrosine kinase inhibitor) and then to liposomal doxorubicin.
