Parotid metastasis from adrenal neuroblastoma.

Neuroblastomas are the most common extracranial solid malignancy in children. In contrast, salivary gland tumors are uncommon in children, accounting for only 1% of all pediatric neoplasms. Parotid metastases are rare; only two cases of parotid metastases from neuroblastomas have been reported with an emphasis on the pathology. We present a case of a parotid metastasis from a neuroblastoma with in-depth description and discussion of its ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) appearances.
