CTICasesTuberous Sclerosis Complex Thoracic Manifestations
Imaging findings
Chest CT in a young patient with angiomyolipomas shows the classic thoracic findings of tuberous sclerosis: fatty foci in the heart, lymphangioleiomyomatosis (LAM) cysts, and numerous ground-glass nodules from multifocal micronodular pneumocyte hyperplasia (type II pneumocyte hyperplasia) that have been stable for years.
Key takeaways
Tuberous sclerosis complex produces a recognizable thoracic constellation of cardiac fatty foci, LAM, and multifocal micronodular pneumocyte hyperplasia (stable ground-glass nodules). The LAM in TSC tends to be less severe than sporadic LAM in this presenter's experience, and recognizing the full spectrum in a patient with angiomyolipomas supports the diagnosis.
