Abstract

An intraneural hemangioma is an extremely rare condition. We report here on an intraneural hemangioma of the ulnar nerve. Microscopic exploration and excision of the lesion resulted in complete relief of the patient's symptoms.

Keywords: intraneural hemangioma, ulnar nerve, microscopic excision

Figures and Tables

Figure 1

Plain radiographs of the left wrist of a 58-year-old woman show numerous irregular shaped phleboliths.

Figure 2

Enhanced computed tomographs demonstrate an oval shaped mass with enhanced vessels and calcifications adjacent to the ulnar artery.

Figure 3

Clinical photographs.(A) A well capsulated cystic mass divides ulnar nerve into halfs and deviates ulnar artery radially. (B) Removed specimen. (C) The cystic mass is 2×1.5×1.5 cm in proximal-distal, mediolateral and anterioposteriorly respectively.

Figure 4

Low-power (A: PAS stain, ×40) and medium-power histologic examinations (B: PAS stain, ×100) reveal large dilated vascular proliferation and capillary-like spaces. (C) Immunohistochemical staining of S-100 protein does not demonstrate any normal neural tissue component in the mass (×100).
