Synovial Haemangioma of the Knee Joint: An Uncommon Condition with Typical MRI Findings

Abstract

Synovial haemangioma is a rare condition mostly affecting the knee joint. In cases of non-specific symptoms the diagnosis of a synovial haemangioma should also be kept in mind in order to avoid delay in diagnosis. Magnetic resonance imaging is the main diagnostic tool to evaluate patients with synovial haemangioma, showing characteristic patterns. A case report of synovial haemangioma of the knee is presented. Magnetic Resonance Imaging (MRI) demonstrated typical signal characteristics and enhancement pattern.
