CTICasesAnterior mediastinal complex cystic mass in leukemia
Imaging findings
Chest CT shows a complex, multi-loculated cystic anterior mediastinal mass with internal septations and coursing vessels, which developed a new solid nodular component when the patient's leukemia worsened. Histopathology showed a squamous-lined cyst with leukemic tumor infiltration.
Key takeaways
Anterior mediastinal cysts can occur in patients with leukemia or lymphoma. Development of a solid component or thickening within a pre-existing cyst indicates active leukemic or lymphomatous infiltration.
