Specific sites include: The vast majority of neuroblastomas are sporadic; however, in rare instances, they may be associated with 1-4: Appearances are non-specific, typically demonstrating an intrathoracic soft-tissue mass or an intra-abdominal mass displacing adjacent organs. Immuno-stains are highly recommended to confirm diagnosis and to exclude other possibilities, Poorly differentiated malignant tumor with morphological features mostly consistent with poorly differentiated neuroblastoma, Q: What is the differential diagnosis? show answer, Neuroblastomas are the most common extra-cranial pediatric solid tumor. Neuroblastoma in the cervical region can provoke Horner’s syndrome, which involves miosis, ptosis hemifacial anhidrosis, and enophthalmos. bone.1,6,8 The incidence of cervical lymph node metastasis ranges from 20 to 30% and reaches 44% in stage C.2,6,8,17–19 Howell et al described a predictable pattern of metastases to the cervical lymph nodes, typically involving level II nodes Keywords olfactory neuroblastoma esthesio-neuroblastoma skull base imaging A vessel arises from the aorta to feed the mass (black arrow). 1,2 The vast majority of teratomas in newborns contain immature tissue components but are still considered benign. Imaging plays an important role in the diagnosis, staging, treatment planning, response evaluation and in follow-up of a case of Neuroblastoma. Microscopically, they form Homer Wright rosettes 3. Radiographics. Neuroblastomas are the most common extra-cranial pediatric solid tumor. Congenital neuroblastoma accounts for 5% of total neuroblastoma cases diagnosed annually, with the majority of cases diagnosed in the first month after birth. It was on November 8, 1895, that Wilhelm Conrad Rӧntgen discovered X-rays. Imaging studies (US, CT, MRI) showed solid masses with vascular displacement and narrowing; intraspinal extension was absent … Eighty percent of NB occur in the abdomen and 10–15% in the chest. 6. Clinical oncology. Often there are areas of necrosis that appear as regions of low echogenicity. 2. The International Day of Radiology (IDoR) takes place every year on November 8. Emergency radiology is a relatively new field within radiology. Primary Cervical Neuroblastoma is a very rare form of malignancy that arises in the cervical or neck region. The tumors typically occur in infants and very young children (mean age of presentation being ~22 months) with 95% of cases diagnosed before the age of 10 years. Neuroblastoma is the most frequent extracranial solid tumor in childhood, but it is seldom diagnosed prenatally. 1984;142 (4): 807-10. Neuroblastomas arise from the sympathetic nervous system 2,3: Intra-abdominal disease (two-thirds of cases) is more prevalent than intrathoracic disease. It is believed to arise from the olfactory epithelium lining the upper third of the nasal septum, the cribriform plates, and the superior turbinates. Typically with pain or a palpable mass and abdominal distension, although numerous other presentations may be encountered due to local mass effect. No calcification. It is most common for radiation to be used in children with high-risk neuroblastoma after stem cell transplant. Cervical Neuroblastoma.— Neuroblastoma of the head and neck frequently represents metastasis from neural crest sympathetic precursor cells in the adrenal gland. Farrelly C, Daneman A, Chan HS et-al. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Neuroblastoma 1. Clinical presentations (other than mass) included stridor and swallowing problems. Presentation of other localization is extremely rare. Neuroblastoma (NB) is one of the most common solid tumors of early childhood. However, a primary cervical location of neuroblastoma is present in 5% of cases (, 22). Calcification occurs in 80-90%.
