Typical imaging findings for neuroblastoma include:

Neuroblastoma, a common malignancy in childhood, particularly arises from neural crest cells and is often found in the adrenal glands or sympathetic ganglia. One of the hallmark features on imaging, such as ultrasound, CT, or MRI, is the presence of calcifications. These can appear as small, punctate densities within the mass due to the presence of differentiated cells and deposition of calcium in areas of necrosis or as a result of tumor maturation.

Hemorrhages may also be observed in neuroblastoma due to its aggressive nature, where the tumor can invade surrounding tissues and outgrow its blood supply, leading to areas of infarction and subsequent hemorrhage. Therefore, the combination of calcifications and hemorrhages is typically seen on imaging studies and supports the diagnosis of neuroblastoma.

While solid masses with cystic necrosis can occur in various tumors, in the context of neuroblastoma, calcifications are particularly characteristic. The presence of lytic bone lesions, while seen in some malignancies, is not a standard finding for neuroblastoma. Enlarged liver alone would not capture the broader range of findings associated with this tumor type, which is more commonly noted to metastasize to the liver rather than just being enlarged due
