This educational exhibit aims to illustrate the imaging characteristics of the most common retroperitoneal tumors in pediatric patients,
with emphasis on neuroblastomas. Furthermore,
the reader will be made aware of possible and often common differential diagnosis pitfalls.
the pediatric population is susceptible to malignancies. Neuroblastoma is the most common extracranial solid malignancy in children and the third most common malignancy of childhood,
with only leukemia and primary brain tumors being more common.
Because of its aggressive nature and late staging at presentation,
it accounts for approximately 15% of childhood cancer deaths.
Often presenting with nonspecific symptoms mimicking benign disease,
the importance of diagnostic imaging...
Findings and procedure details
in recent years,
survival rates for children with cancer increased,
imaging technologies available have evolved to include a wide array of modalities. Ultrasound is the first-line imaging modality in pediatrics,
particularly for patients presenting with a palpable abdominal mass,
therefore being the most common method of diagnosis. On ultrasound,
neuroblastomas are generally solid,
occasionally with small punctate echogenic areas.
the echogenicity on ultrasonography varies;...
Knowing the typical imaging appearance is necessary,
particularly regarding pediatric retroperitoneal masses. Multidisciplinary approach and multi-imaging strategies are essential in defining the correct diagnosis.
