Metastatic neuroblastoma presenting as refusal to use the left upper extremity in a six-year-old girl

Casey Grover, Elizabeth Crawford

Neuroblastoma is the most common extracranial neoplasm in children, commonly presenting at an advanced stage. Despite the high prevalence of metastatic disease with neuroblastoma, metastases to the central nervous system are rare and predominantly involve the spinal cord. We present a case of neuroblastoma with metastases to the brain presenting as refusal to move the left arm. The lesion initially appeared to be both a subdural and epidural hematoma on computed tomography of the head, but upon magnetic resonance imaging, was found to represent metastatic neuroblastoma. In pediatric patients with systemic symptoms and neurologic deficits, metastatic disease, such as neuroblastoma, should be included in the differential diagnosis and appropriate imaging should be obtained.
