We report here a specific case of metastatic brain tumor orienting from rhabdomyosarcoma. An 11-year-old boy came to our hospital with complaints including headache, exophthalmos and tumors in the right frontal and left occipital region. 6 months previously subtotal removal of rhabdomyosarcoma in his right foot had been performed. CT scan demonstrated tumors in the right orbit, right frontal region and left occipital region. The tumors existed bilaterally in the skull and markedly enhanced by contrast medium. But the changes of the cranium were mild, only the dipole was slightly dilated. MRI showed that the tumors were extraaxial masses. Right external carotid angiogram revealed numerous tumor vessels fed by the meningeal artery. On April 3rd, biopsy was performed at the right frontal region. The tumor had spread in the epidural space but the cortical surface seemed to be intact. Histologically, the tumor consisted of small round cells and revealed multinuclear giant cells. It involved the skull bone, dura mater and subdural tissues. Accordingly the tumor was diagnosed as rhabdomyosarcoma. Although tumor increased rapidly, the intracranial region did not change remarkably. It was an interesting phenomenon. Eventually, rhabdomyosarcoma metastasized to the lung, and the patient died due to respiratory distress.
