Abstract
Birth abnormalities affecting the lymphatic system include cystic lymphangiomas. They are rare in adults and typically happen in childhood. The cause of adult cystic hygroma (CH), which has a benign nature, is yet unknown. Seventy-five percent of lymphatic malformations have a CH as their primary site of origin in the head and neck area. We describe a 36-year-old female case of cervical cystic lymphangioma who complained of swelling on the left side of her neck for two years. There was no prior history of fever, trauma, weight loss, appetite loss, discharge, or swallowing difficulties. The doctor advised investigations like computed tomography neck, ultrasound sonography neck, etc., and was diagnosed with cystic lymphangioma. Early physiotherapy seems beneficial in preserving shoulder movement and minimizing pain in individuals. Cryotherapy is useful in treating patients with lymphangioma after surgery to reduce pain and swelling. This clinical case study demonstrates how patients with cystic lymphangiomas can benefit from physical treatment and regain their functional independence.
