  Introduction: Cystic hygromas (lymphangioma) are benign and common developmental anomalies of vasculolymphatic origin.They can arise anywhere along the lymphatic system. However, they are usually located in the neck region and in most cases (80-90%) appear by the age of 2. Most mediastinal cystic hygromas are extensions of cervical lesions, and cystic hygroma confined solely to the mediastinum is rarely encountered. Enlargement of cystic lesions is common and may compress the adjacent organs, causing respiratory distress, feeding difficulties,or vascular compromise.

  Case Report: Herein we report a case of a male child with a cystic mass in the left side of the neck with an extension to mediastinum.This article highlights the clinical and paraclinical findings and management of these cases.

  Conclusion: It is highly recommended that in cases of cervical cystic hygromas evaluation of mediastinum be done to investigate the extension of the cyst. In addition, surgical resection of tumor via cervical incision could be considered.
