A case of cavernous lymphangioma causing shoulder pain

Cavernous lymphangioma is a rare congenital malformation that usually appears in the early childhood. The most common site is head and neck area, where approximately 75% of all lymphangiomas occur. We present a cavernous lymphangioma abutting brachial plexus and causing shoulder pain. A 28-year-old male patient presented with right shoulder pain for 2 months. Neck MRI revealed a lobulated multiseptated cystic mass at the anterior superior aspect of the right neck. Inferior, medial aspect of the mass was abutting brachial plexus. Surgical excision was performed, and pathologic result with immunohistochemical analysis confirmed the diagnosis cavernous lymphangioma.
