Abstract

Background: The cystic hygroma is a benign lymphatic malformation, a rare but potentially serious in its character and its evolutionary trend dissecans. The head and neck region constitutes the favorite seat (75%). If the diagnosis is usually easy, the therapeutic management remains controversial.
Aim: To analyze clinical and paraclinical characteristics of cystic hygroma and to discuss the various therapeutic methods.
Methods: We report a retrospective study about 25 cases of head and neck cystic hygroma collected during a period of 11 years (1998- 2008) in the ENT department of the hospital The Rabta Tunis.
Results: The average age of our patients was 18 years and 5 months. All patients consulted for a neck mass. It was localized in the submandibular region in 7 cases, 3 cases in parotid region, jugulocarotid artery in 3 cases and affecting the posterior triangle in 12 cases. Cervical ultrasound was performed in 22 cases (88%) evoking the diagnosis of cystic hygroma in 16 cases (72%). CT was performed in 10 cases finding hypodense aspect in 8 cases. MRI was carried out in 9 cases. It showed the aspect hyperintense T2, hypointense T1 in 7 cases. Surgical excision was performed in 22 cases and sclerotherapy in 3 patients. During the evolution, a recurrence was observed for each treatment modality.
Conclusion: Surgery is treatment of choice of cystic hygroma. Sclerotherapy may be indicated as an alternative to surgery in localized and diffuse macrocystic forms.
