The carpal boss: a review of different sonographic findings
1MD, Radiologist, Radimagem - Diagnóstico por Imagem, Porto Alegre, RS, Brazil.
Abstract:
Carpal boss is an uncommon condition whose incidence is underestimated and that is frequently confused with other causes of development of tumor-like lesions on the dorsum of the wrist. From the clinical point of view, the main obstacle to its recognition is the nonspecificity of symptoms, frequently attributed to dorsal ganglion cysts, since both conditions share a similar location on the dorsum of the wrist. The assessment by ultrasonography allows for a correct diagnosis and appropriate management, with better chances of resolution of the clinical complaint and lower probability of iatrogenic worsening of the lesion. The present review is aimed at describing the different sonographic findings of carpal boss.
