We present scintigraphic images of a 17-year-old female patient with suspected osteosarcoma recurrence in the distal third of the right tibia, after five years of being under surveillance. To confirm recurrence, it was decided to carry out a scintigraphy and later a SPECT / CT using the Tc99m-sestamibi radiopharmaceutical. Images showed abnormal increase metabolic activity at the level of the right tibial plateau suggesting tumor activity. Histopathology confirmed the diagnosis of osteosarcoma.
