Seema Kembhavi, Sneha Deshpande and Sajid Qureshi

 Paediatric renal tumors are commonly encountered entities in clinical oncology, Wilms’ being the most common

histology. Other histological types include Rhabdoid tumor, Clear Cell Sarcoma, PNET, etc. Though CT/MRI scan is perfomed for staging, it cannot differentiate between the histological types. However, there are a few imaging features which indicate certain pathologies. Rhabdoid tumors of kidney are associated with subcapsular haemorrhage which leads to ‘Subcapsular fluid sign’. We present our case to acquaint the radiologists with this sign and recommend exercising caution while interpreting it.
