Dural Metastasis in Spinal Canal Diagnosed on F-18 Fluorodeoxyglucose Positron Emission Tomography Contrast-Enhanced Computed Tomography Scan in Treated Case of Osteogenic Sarcoma of the Left Femur.

We describe a rare case of osteogenic sarcoma of the right femur; who 2 years after the treatment of primary site developed dural metastasis. Surveillance imaging for unusual pattern of metastasis may lead to earlier detection and treatment decision-making, which may improve survival and quality of life.

Myeloid Sarcoma of the Prostatic Tissue Diagnosed on 18F-FDG PET/CT in Treated Case of Acute Myeloid Leukemia.

Myeloid sarcoma is a rare extramedullary manifestation of acute myeloid leukemia (AML) that often presents during remission or disease relapse. The most common site of relapse being, however, many rare sites has been reported in the existing literature.
