Radiological studies in children with Burkitt
Area of Science:
- Pediatric Oncology
- Radiology
- Urologic Imaging
Background:
- Burkitt's lymphoma is an aggressive B-cell non-Hodgkin lymphoma.
- Genitourinary involvement is common in pediatric Burkitt's lymphoma.
- Accurate staging of genitourinary disease is crucial for treatment planning.
Purpose of the Study:
- To retrospectively analyze radiological findings in the genitourinary tract of children with Burkitt's lymphoma.
- To evaluate the effectiveness of different imaging modalities in detecting genitourinary abnormalities.
- To recommend optimal imaging strategies for this patient population.
Main Methods:
- Retrospective analysis of radiological studies in 18 children with biopsy-proven Burkitt's lymphoma.
- Genitourinary tract evaluation in 15 children using excretory urography, sonography, computerized tomography, and/or gallium citrate scintigraphy.
- Correlation of imaging findings with tumor involvement.
Main Results:
- Genitourinary abnormalities were detected in 9 out of 15 evaluated children.
- Tumor-related changes included renal/ureteral displacement (4), hydronephrosis (3), and intraparenchymal masses (4).
- Gonadal involvement was observed in 3 children (2 boys, 1 girl).
Conclusions:
- Excretory urography has been a traditional choice for genitourinary evaluation.
- Ultrasound and computerized tomography offer more direct visualization of renal and retroperitoneal tumor deposits.
- Pre-chemotherapy imaging should include ultrasound and/or computerized tomography for comprehensive assessment.
Abstract:
The radiological studies of 18 children with biopsy proved Burkitt's lymphoma were analyzed retrospectively. Before therapy the genitourinary tract was evaluated in 15 children by excretory urography, sonography, computerized tomography and/or gallium citrate scintigraphy. Genitourinary abnormalities were detected in 9 children. Changes due to tumor included renal or ureteral displacement in 4 children, hydronephrosis in 3 and intraparenchymal masses in 4. Extrinsic compression of the bladder causing no compromise of function was seen in only 2 children. Gonadal involvement occurred in 2 boys and 1 girl. The modality of choice for evaluating the genitourinary tract in patients with Burkitt's lymphoma has been excretory urography. Since ultrasound and computerized tomography provide more direct information about tumor deposits within the kidney and retroperitoneum, either should be performed in this population before initiation of chemotherapy.
