Intraneural hemangioma of a digital nerve is very rare. Only three cases have been reported in the literature. We present a case of a 39-year-old male who had a soft tissue mass in the region of the right palm. The mass had been present for at least 5 years and gradually increased in size, causing him discomfort. MR imaging revealed a subcutaneous lesion that was isointense with the muscle on T1-weighted images and partially hyperintense on T2-weighted images. Morphologically, the lesion demonstrated tubular structures suggesting feeding or draining vessels. Therefore, we diagnosed the tumor as hemangioma and planned to perform resection. In the operation, the mass was found to involve a digital nerve. We performed en bloc resection of the hemangioma with the digital nerve, and reconstructed with sural nerve grafts to bridge the gap in the nerve. At 15 months after this operation, the patient remains free of recurrence. The recovery of sensory perception is very good and he has no pain. In cases of hemangioma around peripheral nerves, we should consider the possibility of peripheral nerves involvement in the differential diagnosis.
