Abstract:
Two middle-aged-patients each presenting with a progressively enlarging mass in the first dorsal web space of their hands are reported. Magnetic resonance imaging (MRI) demonstrated the cause to be a hypertrophic first dorsal interosseous muscle, with normal T1, T2 and post-gadopentetate dimeglumine signal characteristics. The ability of MRI to diagnose anatomical variants of hand muscles is important in the clinical management of patients with these pseudotumours.Keywords: hand; magnetic resonance imaging; pseudotumours; soft tissue tumours
