Unusual clinical presentation of hodgkin lymphoma in a child: Both spinal cord compression and hydronephrosis

Background: Hodgkin lymphoma (HL) is predominantly a nodal disease with extranodal presentation being uncommon. Presentation with neurological symptoms is not uncommon in adult patients with HL. Subdiaphragmatic involvements are less common especially in childhood. In the literature, there has been no case which presented with both spinal cord compression and bilateral hydronephrosis in pediatric patients with HL. Observation: We report a 9-year-old boy diagnosed with HL who presented with bilateral hydronephrosis and epidural involvement. Conclusion: Differential diagnosis of abdominal mass in patients presenting with spinal cord compression and/or hydronephrosis should include HL. Retrograde J ureteral stenting is the treatment of choice for malignant ureteral obstruction.
