Left adrenal neuroblastoma with normal-appearing urogram.

Area of Science:

• Pediatric oncology
• Diagnostic imaging
• Radiology

Background:

• Adrenal neuroblastomas are common pediatric malignancies.
• Intravenous urography is a standard diagnostic tool for adrenal masses.
• Typical presentations involve kidney displacement or contour distortion.

Purpose of the Study:

• To describe an unusual presentation of left adrenal neuroblastoma.
• To highlight imaging findings that may mimic other intra-abdominal tumors.
• To inform diagnostic strategies for pediatric adrenal masses.

Main Methods:

• Retrospective review of five pediatric cases.
• Analysis of intravenous urography findings.
• Comparison of displacement patterns with pancreatic tumors.

Main Results:

• Five children presented with left adrenal neuroblastoma.
• The neuroblastoma mass was located anterior to the kidney in all cases.
• Imaging demonstrated displacement vectors similar to pancreatic body or tail tumors.

Conclusions:

• Left adrenal neuroblastomas can present anteriorly, challenging typical diagnostic assumptions.
• Radiologists should consider adrenal neuroblastoma in the differential diagnosis of anteriorly located masses mimicking pancreatic tumors.
• Awareness of this atypical presentation can improve diagnostic accuracy in pediatric oncology.
