Intraspinal lymphangioma: 2 case reports and literature review

Abstract

Background Lymphangioma of the soft tissue is not uncommon. However, as far as the authors know, intraspinal lymphangioma is clinically rare and very few cases have been reported previously. Methods Two patients who had backache and acratia of the lower limbs and difficulty in relieving themselves were examined by plain radiography and magnetic resonance imaging before surgery. Treatment consisted of the usual technique of surgical resection of the tumor microscopically. Histological examination of the resected material confirmed the diagnosis. Postoperative follow-up assessment was performed by magnetic resonance imaging. Results Intraspinal lymphangioma is very rare clinically and its cause remains controversial. Magnetic resonance imaging can obtain precise position fixing, but it is hard to make preoperative qualitative determination. The most effective treatment of intraspinal lymphangioma is to excise it totally. Conclusions The clinical appearance of intraspinal lymphangioma has no character. Magnetic resonance imaging is important in diagnosing it. The most effective treatment of intraspinal lymphangioma is to excise it totally. Further observation is recommended because of the possibility of local recurrence.
