CTICasesMyocardial Lipomas in Tuberous Sclerosis Complex

Imaging findings
Abdominal CT slices demonstrate multiple solid masses in both kidneys consistent with angiomyolipomas, confirming a clinical diagnosis of tuberous sclerosis. Thoracic CT shows multiple small, non-enhancing fatty masses throughout the myocardium, including the right ventricle and the lateral to anterolateral wall of the left ventricle. High-resolution chest CT also reveals scattered, thin-walled cysts characteristic of mild lymphangioleiomyomatosis.
Key takeaways
Cardiac fat deposits or lipomas are a recognized manifestation of tuberous sclerosis complex. These benign lesions typically behave like lipomas, containing pure fat without soft-tissue enhancement, and must be distinguished from other cardiac tumors or rhabdomyomas. Radiologists should routinely inspect the myocardium for these fatty lesions when imaging patients with known tuberous sclerosis.
