Magnetic resonance features and cranial nerve involvement in pediatric head and neck rhabdomyosarcomas

ConclusionCranial nerve involvement is frequent in pediatric head and neck RMS and occurs secondary to “geographic” invasion due to direct extension through skull base foramina or cavernous sinus. These tumors never showed distant perineural metastatic disease as is seen in cases of adult head and neck carcinomas. This implies a different biological interaction between the nerves and these tumors in comparison to adult H&N tumors.
