Deposit of uric acid crystals, in the form of monosodium urate crystals, in people with longstanding hyperuricemia (high levels of uric acid in the blood)
US findings of interest were double contour sign, tophus, and snowstorm appearance.
2
A biopsy of the subcutaneous nodule showed a typical appearance of tophus.
3
This variability in signal intensity could be related to calcium within a tophus.
4
Gout was defined by synovial fluid or tophus aspirate microscopy by certified examiners in all patients.
5
All but one tophus showed homogeneous enhancement.
6
Methods: We performed a cross-sectional study of consecutive rheumatology clinic patients with ≥1 swollen joint or subcutaneous tophus.
7
A gouty tophus occasionally mimics an infectious or neoplastic process, and MR imaging may be obtained under these circumstances.
8
Sensitivity was higher among subjects with a disease duration of ≥2 years and among subjects with subcutaneous nodules on examination (suspected tophus).
9
Smooth, dark gray tophus predominates; it forms the bed of the Rio Pasig, and rising forms hillocks in the vicinity of the city of Binangonan.
