ANSWER: LEFT PARASPINAL GANGLIONEUROMA

Ganglioneuromas are derived from the primordial neural crest cells that form the sympathetic nervous system. They most commonly arise in the paravertebral sympathetic chains of the posterior mediastinum or retroperitoneum.

Ganglioneuromas tend to occur in the paediatric population (Median age-7yrs). 

Well-defined solid masses 

20% lesions demonstrate calcifications, typically fine and speckled.

Contrast enhancement ranges from none to heterogeneous enhancement.

Treatment consists of complete surgical resection.

P.S – Hydronephrosis in this case was due to mass effect on the ureter.
