Clinical presentations and imaging findings of neuroblastoma beyond abdominal mass and a review of imaging algorithm.

ABSTRACT

Neuroblastoma is one of the most common malignant neoplasms in childhood. The most common clinical presentation of this tumour is abdominal mass. However, affected children may have various clinical presentations as a result of disseminated metastatic disease or associated paraneoplastic syndromes at the time of diagnosis. In this article we have outlined the imaging findings in seven patients with "extra-abdominal" presentation of neuroblastoma and the pitfalls in making the correct diagnosis. The purpose of this pictorial review is to alert the general radiologist to the possible presentations of this common childhood malignancy to derive early detection and diagnosis.
