Neuroblastoma is the most common extracranial pediatric solid tumor and arises most often from the adrenal glands. However, this tumor can occur anywhere along the sympathetic nervous system. Its clinical presentation is variable and depends on the location and extent of the mass. We present the case of an infant who initially had a palpable mass on his back, later developed lower extremity weakness, and was subsequently diagnosed with a paraspinal neuroblastoma. MRI was key in visualizing compression of the lower thoracic spinal cord by the tumor, explaining the patient’s symptoms and necessitating tumor debulking. The course of the patient’s treatment was complicated by a tumoral hemorrhage that required emergent embolization by an interventional radiologist. This case highlights options for the management of neuroblastoma, including chemotherapy, embolization, and surgical resection, with an emphasis on interdisciplinary decision-making.
