Osseous metastasis in medulloblastoma: MRI findings in an unusual case

Osseous metastasis in medulloblastoma: MRI findings in an unusual case

An 11-year-old boy with a history of medulloblastoma developed blastic osseous metastases. The metastases were detected by noting diffuse areas of low signal intensity within the calvarium on T1-weighted and T2-weighted magnetic resonance (MR) scans of the brain. The MR appearance of osseous metasta...

Zusammenfassung:An 11-year-old boy with a history of medulloblastoma developed blastic osseous metastases. The metastases were detected by noting diffuse areas of low signal intensity within the calvarium on T1-weighted and T2-weighted magnetic resonance (MR) scans of the brain. The MR appearance of osseous metastases in medulloblastoma has not been reported previously. Extraneural metastases in medulloblastoma are relatively rare. The literature is briefly reviewed.
