Computerized tomography in rhabdomyosarcoma of the head and neck

Rhabdomyosarcoma of the head and neck may be treated with surgery, radiotherapy and chemotherapy or a combination thereof. Precise delineation of the full extent of the tumor in the head and neck is essential. Routine radiographs with hypocycloidal tomography and CT are complementary in defining the full extent of the lesion. Tomography is superior to CT scanning in demonstrating fine bone detail. Demonstration of the soft tissue tumor and its extensions is better seen on CT. The ability to discriminate differences more accurately in densities allows computerized tomography to appreciate better the integrity of the bone margins such as the thin walls of the sinuses.
