Lymphangiomas are benign collections of blind-ended lymphatic and vascular channels. Lesions typically occur in the soft tissues of the head and neck, although any region of the body can be affected. Involvement of the spine is very rare. A complete resection is generally curative. On rare occasions, these tumors are complicated by infection or hemorrhage. The authors present an unusual case of a hemorrhagic lymphangioma in a 1-year-old male child. The lesion originated in the mediastinum and extended into the cervicothoracic epidural space via a neural foramen. This resulted in an acute epidural hematoma and quadriparesis. Emergency decompression resulted in full neurological recovery. This may be the first report of a lymphangioma resulting in an acute epidural hematoma and quadriparesis.
