RESUMO
Abstract We describe a very unusual case of a 49-year-old man with tophaceous gout involving and infiltrating the base of the anterior cruciate ligament of the left knee. To our knowledge, such a case has never been reported in the literature, although gout is well known and widely studied. Magnetic resonance imaging findings and differential diagnosis were analyzed before arthroscopy. Tophaceous gout was suspected at arthroscopy and confirmed on pathologic examination. Treatment consisted of partial removal of the tumor by arthroscopy, conserving the anterior cruciate ligament.
