Abstract:
The radiographic findings of perirenal amyloidosis have not previously been described. A patient with multiple myeloma and primary amyloidosis (AL) with secondary hydronephrosis as examined on plain film, retrograde ureteropyelography, computed tomography, and magnetic resonance imaging is presented. This case illustrates perirenal amyloidosis and demonstrates the utility of CT and MRI in patient management and surgical treatment.
Insights
Radiographic findings of perirenal amyloidosis, a rare complication of amyloid light-chain (AL) amyloidosis, are presented. This case highlights the diagnostic value of CT and MRI in managing secondary hydronephrosis.
Area of Science:
- Nephrology
- Radiology
- Oncology
Background:
- Perirenal amyloidosis is a rare condition.
- Amyloid light-chain (AL) amyloidosis is associated with multiple myeloma.
- Radiographic findings of perirenal amyloidosis have not been previously documented.
Observation:
- A patient with multiple myeloma and AL amyloidosis presented with secondary hydronephrosis.
- Radiographic examinations included plain film, retrograde ureteropyelography, computed tomography (CT), and magnetic resonance imaging (MRI).
Findings:
- The case illustrates the characteristic radiographic appearance of perirenal amyloidosis.
- CT and MRI were instrumental in visualizing the extent of perirenal involvement and secondary hydronephrosis.
Implications:
- This case expands the understanding of the radiographic manifestations of amyloidosis.
- CT and MRI are valuable tools for diagnosing and managing perirenal amyloidosis and associated complications.
- Improved diagnostic capabilities can aid in patient management and surgical treatment planning.
