We report a rare case of solid-cystic pancreatic tumour presenting as a spleno-renal angle mass in a 14-year-old girl. Transabdominal ultrasound showed a well-capsulated mass with irregular heterogeneous echogenic foci intermixed with small hypoechoic components in a bizarre pattern. The interactive roles of ultrasound in lesion localisation, characterisation, and guidance for percutaneous needle biopsy are described. Differentiating this rare, low grade malignant paediatric tumour from other lesions in the spleno-renal angle is essential for both surgical planning and prognosis.
