|Title : Case 626|
Age / Sex : 74 / F
Chief complaint : Left hip pain
Answer: Dialysis-related amyloidosis
Findings: Multiple bone erosions in both femoral head and neck. Low signal mass-like material in both femoral head and hip joint (left>right).
Differential Diagnosis: Tenosynovial giant cell tumor, gout, AVN
Discussion: Deposition of β2-microglobulin in joint of patients undergoing long-term hemodialysis. Conventional radiograph will show cystic radiolucencies with sclerotic rim, without matrix calcifications, commonly in hips, wrists, shoulders, knees, spine. MRI will show mass of low signal intensity, with variable T2 signal as result of combination of amyloid deposits and fluid collection.
