CTICasesThymoma
Imaging findings
Chest CT shows diffuse, thin-walled, spherical pulmonary cysts and multiple low-attenuation retroperitoneal masses representing lymphangioleiomyomas, alongside a large, solid, lobulated anterior mediastinal mass. Histopathology of the anterior mediastinal mass confirmed a thymoma.
Key takeaways
Lymphangioleiomyomatosis is a rare cystic lung disease affecting females, often associated with renal angiomyolipomas and retroperitoneal lymphangioleiomyomas. The co-occurrence of a thymoma in the anterior mediastinum represents a coincidental collision of two distinct neoplastic processes.
