Abstract
Hemangiomas are benign neoplasms of endothelial cells origin, rarely found in hand region. Authors report a 62-year-old female with capillary hemangioma of right index finger causing a neuropathic symptom via nerve compression. A space-occupying vascular lesion surrounding the radial digital nerve was revealed in magnetic resonance imaging (MRI), which was removed under microscopic assist. The digital nerve was decompressed consequently. The mass was firmly attached to both the digital nerve and digital artery, requiring a meticulous microscopic dissection to preserve the nerve and artery. Compression neuropathy caused by space-occupying lesions is rare and its diagnosis is often difficult. A microscopic surgical approach can be used to successfully relieve neuropathic pain after proper diagnosis established by diagnostic tools such as MRI as in this case.
