An unusual imaging finding mimicking double contour sign following ultrasound-guided intra-articular knee injection of steroid: A case report

Agri. 2024 Jan;36(4):269-271. doi: 10.14744/agri.2022.10179.

Abstract

Examination of monosodium urate crystals in the synovial fluid remains the gold standard for the diagnosis of gout. On ultra-sound (US) examination, the double contour sign (DCS) is one of the most common imaging findings of gout. In this article, we present, for the first time, a unique imaging finding mimicking DCS after US-guided intra-articular knee injection of steroid and discuss it in light of the literature data.
