Fixed Flexion Deformity of the Middle and Ring Fingers in Adult Caused by Intramuscular Hemangioma of the Forearm: A Case Report
Vilai P , Manop P Mail, Vanichanon C

Intramuscular hemangioma (IMH) of the upper extremity is extremely rare and mostly found in children. The authors presented a 39-year-old female with an unusual case of fixed flexion deformity of the middle finger and ring finger with deep forearm pain for three years. The patient was diagnosed with IMH of the flexor digitorum superficialis muscle. Excision of the IMH was performed and intra-operatively passive extension of PIP joints was achieved. After 12 months follow-up, the patient was satisfied with the outcomes with no recurrence of flexion contracture. IMH of the upper extremity is an uncommon disease, especially in adults. It should be considered in patient who presented with deep forearm pain and finger flexion deformity. Early investigation should be performed and surgical removal remains the treatment of choice. Furthermore, tendon transfer should be reserved in case of functional deficits.
