Revision as of 15:10, 15 April 2022
Background
- Arises from primitive ganglion cells of sympathetic nervous system
- Synthesize and secrete catecholamines
- Most common neoplasm in 1st yr of life
- May arise anywhere along sympathetic nervous system
- Adrenal gland (40%)
- Abdomen (25%)
- Chest (15%)
- Mets are most common in lymph nodes, bone marrow, cortical bone, dura, orbits, liver, and skin
Clinical Features
- Depends on location
- Abdominal mass
- 2/3 of primary neuroblastoma arise in the abdomen
- Abdominal pain or constipation
- Proptosis or periorbital ecchymoses
- Horner syndrome: mitosis, ptosis, anhidrosis
- Paraspinal mass
- Spinal cord compression, which can cause localized back pain or weakness
- Systemic symptoms, bone pain, anemia
- Abdominal mass
- Opsoclonus-myoclonus: rapid, dancing eye movements, rhythmic jerking of trunk or limbs, and/or ataxia
- paraneoplastic syndrome highly associated with neuroblastoma
- Neutropenia/pancytopenia suggests bone marrow involvement
Differential Diagnosis
- Wilms' tumor
- Hepatoblastoma
- Lymphoma
- Other adrenal gland tumor
Evaluation
- Catecholamines; VMA and HVA of serum and urine
- CT or MRI
- Although US is often the initial radiologic study of choice for abdominal mass, you need to look at the primary tumor site and possible nodes on CT or MRI
- CXR
- Biopsy for definitive diagnosis
Management
- Admission for tumor biopsy and further workup
