Renal tumoural calcinosis: Extensive and multifocal form

Area of Science:

• Nephrology
• Radiology
• Nuclear Medicine

Background:

• Renal tumoural calcinosis is a rare condition characterized by calcium deposition in tissues, often associated with chronic kidney disease.
• The incidence of renal tumoural calcinosis is increasing, linked to improved life expectancy in patients undergoing dialysis.
• Accurate detection and assessment of osseous involvement are crucial for patient management.

Purpose of the Study:

• To highlight the utility of whole body skeletal scintigraphy in diagnosing renal tumoural calcinosis.
• To present an illustrative case of extensive renal tumoural calcinosis detected via bone scan.

Main Methods:

• Whole body skeletal scintigraphy utilizing Technetium-99m methylene diphosphonate (99mTc-MDP) was performed.
• The imaging technique is known for its high sensitivity in detecting sites of abnormal bone metabolism and calcification.

Main Results:

• Skeletal scintigraphy with 99mTc-MDP demonstrated widespread osseous involvement consistent with extensive renal tumoural calcinosis.
• The bone scan effectively identified multiple sites of calcification throughout the skeleton.

Conclusions:

• Whole body skeletal scintigraphy with 99mTc-MDP is a sensitive and valuable tool for detecting and evaluating the extent of renal tumoural calcinosis.
• This imaging modality aids in the diagnosis and management of patients with this rare condition.
