Giant Cystic Mediastinal Lymphangioma

Area of Science:

• Thoracic Surgery
• Diagnostic Imaging
• Vascular Malformations

Background:

• Cystic lymphangioma, a rare benign tumor originating from lymphatic vessels, predominantly affects pediatric populations.
• Mediastinal tumors, while diverse, necessitate thorough diagnostic evaluation to rule out various pathologies.
• Adult presentation of cystic lymphangioma is uncommon, often leading to incidental diagnosis.

Purpose of the Study:

• To report a rare case of a giant cystic mediastinal lymphangioma in a 36-year-old female.
• To emphasize the importance of diagnostic imaging in identifying mediastinal masses.
• To highlight the role of prompt surgical intervention in managing mediastinal lymphangiomas.

Main Methods:

• Case report of a 36-year-old female patient.
• Diagnostic workup included thoracic X-ray, computed tomography (CT), and nuclear magnetic resonance (NMR) imaging.
• Surgical consultation with the Cardio-Thoracic Surgery Department for lesion excision.

Main Results:

• A giant cystic mediastinal lymphangioma was incidentally discovered in an asymptomatic 36-year-old female.
• Imaging studies confirmed the presence and extent of the mediastinal mass.
• The patient was deemed a candidate for surgical excision.

Conclusions:

• Cystic lymphangiomas constitute a small percentage (0.7-4%) of mediastinal tumors, typically asymptomatic in adults and diagnosed incidentally.
• Comprehensive imaging, including CT and NMR, is vital for accurate diagnosis and surgical planning.
• Early diagnosis and surgical management are essential to prevent tumor growth and potential complications impacting surgical approach.
