Neuroblastoma Masquerading as a Septic Hip Infection in a Three-Year-Old

Metastatic neuroblastoma to the bone and septic joint shares the same incidence in age and clinical symptomology. Here we discuss a three-year-old male who presented with anemia, persistent hip pain, and a refusal to bear weight. A thorough evaluation based on a broad differential diagnosis allowed for an expedient diagnosis of metastatic neuroblastoma. The timely diagnosis allowed for rapid enrolment in a children's oncology group (COG) clinical trial for advanced neuroblastoma. The patient tolerated the therapy without adverse events and remains in remission.
